1 WHAT IS AU PIC18F SERIAL BOOTLOADER?
Au PIC18F Serial Bootloaders are low cost yet high reliable solutions for upgrading PIC18F Microcontroller (MCU) firmware via RS232 interfaces. They are suitable for any target boards/products equipped with Microchip® PIC18F microcontrollers and RS232 interfaces.
With the Au PIC18F bootloader program embedded in the PIC18F MCU, new application firmware code can be upgraded into PIC18F MCU in-field without bringing the device back to manufacturer’s facility. The application firmware code is downloaded via a PC RS232 interface. So there is no need to open/damage products original package/enclosure.
2 TWO SOLUTIONS
There are two solutions available for Au PIC18F serial bootloader: non-encrypted solution and encrypted solution.
• Non-encrypted solution uses regular "Hex" format files for firmware upgrade; it can be used for products with no requirements of intellectual property (IP) protection.
• Encrypted solution uses encrypted algorithm in a proprietary "Aud" format to prevent the PIC18F firmware from directly exposure to third parties. The unique dynamic encryption algorithm makes firmware-hack mission impossible. The encryption feature helps preventing the firmware intellectual property from being copied/miss-used by un-authorized third parties.
With Au Group Electronics developed encryption technology, for any encrypted solution:
1. Each encrypted firmware code (*.aud file) is unique;
2. Each encrypted firmware code (*.aud file) is traceable with a unique digital watermark;
3. Each firmware-downloading process is unique.
All these three features provide a good protection of Intellectual Property (IP).
MCU resources used for both solutions are listed in Table 1-1. Please note, EEPROM is reserved for software trigger feature.

Au Group Electronics is proud to announce the following Au Group Electronics developed products are maintained and protected by PIC18F Encrypted Serial Bootloader: six editions of J1939 Simulators, J1939 Data Centers, J1939 Message Centers, J1939 Interpreters, etc. Au Group Electronics also provide/design other PIC family bootloaders with or without encryption features, e.g. dsPIC30Fs, dsPIC33Fs, etc.
In this user manual, we will use Au J1939 Simulator Gen II as an example to demonstrate how easy an Au PIC18F Serial Bootloader can be applied to a product (Chapter 1.7).
Note: Microchip, PIC18F, PICkit 2, and ICD2 are trademark of Microchip Inc.

The Microchip PICkit2 is a USB based ICSP (In Circuit Serial Programming) programmer. Since its first release, Microchip has opened all resource of PICkit2 to the public, which includes all software source code and hardware schematics. With this open-architecture, DIY fans and experts can add hardware features, fix bugs, or modify the source code for operation systems other than Microsoft Windows, e.g. Linux.

PICkit2, MPLAB, ICD2, ICD3, RealICE and PICkit 2 programmer are trademarks of Microchip Technology Inc.

Note: This documents reflect only personal opinions and experiences, it shall not be used for any other purpose other than open-source/education purpose.

Fundamental Design of Microchip PICkit 2

1.1 USB Power Supply and Connection
PICkit 2 is a USB powered device, it gets all the power from PC USB +5V power supply. In default, USB Mini-B connector (Figure 1-a) is used. However, other types of USB connectors can also be used, e.g. USB Type B connector (Figure 1-b).

The USB specification provides a 5 V supply on a single wire from which connected USB devices may draw power. The specification provides for no more than 5.25 V and no less than 4.75 V (5 V±5%) between the positive and negative bus power lines.

A USB "unit load" is defined as 100mA in USB 2.0, and was raised to 150mA in USB 3.0. A maximum of 5 unit loads can be drawn from a port in USB 2.0, and was raised to 6 in USB 3.0. There are two types of devices: low-power and high-power. Low-power devices draw at most 1 unit load, with minimum operating voltage of 4.4V in USB 2.0, and 4V in USB 3.0. High-power devices draw the maximum number of unit loads supported by the standard. All devices default as low-power but the device's software may request high-power as long as the power is available on the providing bus.

The PICkit 2 is a low-power device. Its USB current limit is set at 100mA. When the total current for both target and the PICkit 2 programmer exceeds this current limit, the USB port may turn off. In this case, the target need be powered externally.

Since PICKit 2 itself can draw electrical current as high as 75mA, the current draw for the application circuit should be limited to 25mA if PICkit 2 programmer supplies power. It is always a good practice to use external power when programming hi-performance/power-hungry chipsets, such as: dsPIC30Fs (they normally consume high current when running at high speed).

When a PICkit 2 is used to power application circuit, ensure that the application circuit does not slow the Vdd rise-time to longer than 500 us.

The +5V USB power supply is connected to capacitor C5 and C6 internally (Figure 2-a) for local voltage stability control. A 2.7Kohm resistor R34 was added after the PICKit 2 "red button" revision. R34 is used to bleed capacitor C5 and C6 when a USB connection is off. This helps improving the PICkit 2 HID-recognition performance when it is re-connected to PC in a very short interval.

PIC18F2550 (USB microcontroller) is the soul of the PICkit 2. Two pins (D+ and D-) of PIC18F2550 are used to connect to USB Data+ and Data- from PC (Figure 2-b). All PC application program communicate with PIC18F2550 via these USB D+/D- connection.

An internal 3.3V regulator is used to power the internal transceiver. A 0.47uF capacitor C7 (Figure 2-b) is used to stabilize the 3.3V supply. For PICkit 2 DIY (Do-It-Yourself), the "USB Voltage Regulator" configuration bit for PIC18F2550 must be set as "Enabled" (Figure 3).

1.2 PIC18F2550 ICSP Connection
Like any other PIC microcontroller, the PIC18F2550 is able to be re-programmed even when it is soldered on the printed circuit board. The 5-pin ICSP connection is illustrated in figure 4-a and figure 4-b. This design provides the reprogramming and recovering capability on the chipset whenever there is anything messed up with the PICkit 2 firmware. To reprogram or recover the PIC18F2550 in the PICkit 2, another functional PIC programmer, such as PICkit 2, ICD2, ICD3, RealICE, etc. is needed. It is always a good practice to have at least two PIC programmers, e.g. one ICD2 and one PICkit 2, or two PICKit 2.

PIC18F2550 ICSP Pins

1.3 PICkit 2 ICSP VPP Boost voltage Generation and Control Mechanism
As a universal PIC programmer, the VPP signal generation circuit on PICkit 2 must cover all PIC microcontrollers. The VPP voltage requirement varies from 3.3V (dsPIC33F) to 13V (PIC18F); the VPP electrical current specification is normally less than 10mA. PICkit 2 itself runs at 5 volt. Thus, an on-board switch mode boost circuit (Figure 5) is used to generate any voltage higher than target voltage ("+V_TGT" and "VDD_TGT_OUTPUT" (Figure 6-b)).

To stabilize the power supply of the switch mode boost circuit and damp the possible power noise sending back to the main power supply, C13 and C14 is used, and they should be placed as close as possible to inductor L1. The PIC18F2550 controls the switch frequency and dwell time of Q4 (both MMBT2222 (600mA) and MMBT3904 (200mA) can be used.). For DIY user, the capacity for inductor L1 should be at least 10mA. When Q4 is on, electric current flow through L1 and Q4, energy is stored in L1. When Q4 is turned off, a high voltage is generated at pin 2 of L1. The Schottky diode D3 will be on when the induced voltage is higher than the voltage on capacitor C15, electric current will keep flowing through L1 and D3. This will charge the capacitor and raise its voltage to desired VPP voltage. Resistor R22 and R24 generate a feedback signal which is send back to PIC18F2550. With "VPP_FEEDBACK" signal, the PIC18F2550 can then precisely adjust switch frequency and dwell time on Q4. This feedback boost circuit mechanism can generate a voltage higher than "VDD_TGT_OUTPUT". A large value and high voltage rated capacitor should be used as C15. R22 and R24 should use 1% or better accuracy resistor. A Schottky type diode must be used at D3 to secure low voltage drop and power consuming.

R23, R25, R27, Q7 and Q6 are used as ON/OFF switch of VPP. When "VPP_ON" is set high logic by PIC18F2550, Q7 will be on, which will then turn on Q6, the voltage on C15 will appear on PICkit 2 ICSP VPP Pin. When a low logic is send to Q7 by PIC18F2550, Q7 and Q6 will be turned off. This in turn cut off the VPP supply to external circuit. When Q6 and Q8 are both off, the PICkit 2 ICSP VPP Pin is floating. The PIC18F2550 can turn on Q8 and it will clamp PICkit 2 ICSP VPP Pin to ground. This has been used in PICkit 2 self test procedure. The overall VPP control procedure makes it possible to turn on and turn off VPP at any time.

1.4 PICkit 2 ICSP Vdd Generation and Isolation Mechanism
PICkit 2 can provide Vdd to power external circuit or isolate the internal generated Vdd from the external Vdd when external Vdd is detected.

On Figure 6-a, the PIC18F2550 will control the PWM dwell time of "VDD_TGT_ADJ" output, which is integrated by capacitor C8 and resistor R4. A reference voltage is generated at the negative input (U2-pin-3) of a rail to rail operational amplifier U2. R5 and R6 is used to generate voltage feedback to positive input of U2. R7 is used to generate a small electric load and bleed the capacitor (e.g. C11 and C12) when power is turned off. MOSFET Q1 is controlled by U2 in switch mode. When "+V_TGT" is lower than the voltage PIC18F2550 set, feedback voltage on U2-pin-1 is less than voltage on U2-pin-3, the output on U2-pin-4 is Low, MOSFET Q1 will turn on, the "+V_TGT" will increase. When "+V_TGT" increased to high enough to trigger U2-pin-4 to output a High logic, Q1 will be off. When Q1 is off, the "+V_TGT" will stop rising.

Overall, The PIC18F2550 set a target voltage at U2-pin3 by outputting a PWM wave, then the hardware loop of R5, R6, U2-pin-1, U2-pin-4 and Q1 automatically adjust and generate a stable output of "+V_TGT" at all load. This step-down circuit can output a 2.5V to 5V "+V_TGT" for internal and external circuits. For DIY user, U2 must be a rail-to-rail type operational amplifier; and Q1 must be a MOSFET to keep a very low voltage drop.

Capacitor C11 and C12 (Figure 6-b) is used to stable the "+V_TGT" for transient response. U6-Q2 (P) is used to turn on/off "+V_TGT" and isolate "+V_TGT" from "VDD_TGT_OUTPUT". When "VDD_TGT_P" output from PIC18F2550 is High (default), U6-Q2 (P) is off, no internally generated "+V_TGT" will be output to "VDD_TGT_OUTPUT". When "VDD_TGT_P" output from PIC18F2550 changes to Low, U6-Q2 (P) is on, PICKit 2 supplies Vdd to external circuits.

For protection purpose, D4 is also used to isolate internal generated Vdd with external circuit Vdd. This protection mechanism is implemented just in case anyone turns on external power supply while PICkit 2 is supplying power to external circuit. A high current Schottky type diode must be used at D4. Due to the voltage drop on D4, the maximum Vdd after D4 is around 4.8~4.9V when USB supply is 5V. Use other type of diode or small current Schottky type diode at D4 will lead to higher voltage drop. This is critical for some PIC chipset which requires a minimum Vdd 4.6V for good ICSP programming practice (an alternative approach is: always use external Vdd for those PIC chipset).

R12, R13, U6-Q1 (N) and R26 are used to detect external power supply. When the "VDD_TGT_N" output from PIC18F2550 is High logic, U6-Q1 (N) is turned on, the "VDD_TGT_FB" input to PIC18F2550 will read Low if there is no external Vdd exist, otherwise, the "VDD_TGT_FB" will read High. Every time, before connecting PICKit 2 internal Vdd to external circuit, PICkit 2 will automatically detect if external Vdd exist or not, if it does or when status is changed, a warning will be displayed.

Diode D1 and Resistor R17 generate a clamping voltage reference for PICKit 2 PGD PGC and AUX signal. Resistor R17 creates some electric load and make sure there is enough electric current flow through D1. D1 will generate some voltage drop across pin 1 and pin 2, this will compensate the Vbe voltage drop on Q2, Q3 and Q5 (MMBT3906) (Figure 7-a, 7-b, 7-c).

1.5 PICkit 2 ICSP PGD, PGC, AUX Signal Generation and Voltage Clamping Mechanism
Per ICSP definition, the PGC is an output only signal, PGD is a bi-direction signal. The AUX is not used for ICSP, but can be used as bi-direction signal too. Theoretically those three pins can all be used as bi-directional function. However, due to the fact the PIC18F2550 pin RA2 (PGD) and pin RA3 (PGC) are TTL type I/O, pin RA4 (AUX) are ST type I/O. When Vdd is less than 3.6V, any operation involved with RA4 will not function correctly when TTL type input/output logic is needed. This has post some Vdd limit to some 3.3V only 11LC, 24LC EEPROM devices. Au Group Electronics developed 3-in-1 and 2-in-1 mini-labs include level-shift circuits to overcome this design limit.

Besides Programming EEPROMs and PICs, PICKit 2 can also be used as many other purpose, e.g. a Logic Tool, a UART Tool, etc.

As we have seen, the PIC18F2550 itself is working with a +5V supply, it can work directly with any +5V capable target PIC chips.

However there are more and more target PIC chips don't support +5V supply anymore, e.g. some of them can only work with voltage/signal at 3.3V, 2.7V etc.

It is a challenge job to have these PIC chips covered by PICkit 2. This technical challenge has been solved by some simple voltage level clamping technology as shown on Figure 7-a, 7-b, 7-c.

On figure 6-b, a voltage reference "CLAMP_REFERENCE" is generated by diode D1 and Resistor R17. It has been used to control the base (pin 2) on PNP transistor Q2, Q3, and Q5 (MMBT3906, Figure 7-a, 7-b, 7-c). Whenever a PIC18F2550 output a high logic (at pin AUX, ICSPCLK, ICSPDAT), and ICSP Vdd is not +5V, the Q2, Q3 and Q5 will kick-in and clamp the output voltage to Vdd level. Due to the fact there is always a voltage drop Vbe between base and emitter of transistor MMBT3906, a diode D1 is used in figure 6-b to compensate this voltage drop.

Resistors R10, R14 and R19 are used to limit the current draw from the PIC18F2550. Due to the fact VOH will drop when IOH increase (Figure 8), pin AUX (RA4), pin ICSPCLK (RA3) and pin ICSPDAT (RA2) will all be working within its safe zone.

1.6 PICkit 2 Human Machine Interface
One push button (Figure 9-a) and three LEDs (Figure 9-b) are used in PICkit 2 as human machine interface. A 10K resistor R32 is used as pull-up, when there is no push button action, a logic High will send to PIC18F2550. When the "Program" push button SW1 is pushed, a logic Low will send to PIC18F2550. The push button is used to force PIC18F2550 enter bootloader mode at power-up, or trigger chip programming after power-up. The "POWER" LED will be constantly lit when PICkit 2 is power up. The "TARGET" LED will lit when PICKit 2 supply Vdd to external circuits. The "BUSY" LED will lit when PICkit2 is communicating with PC or programming a chip. Resistors R1, R2, and R3 are used to limit the current to LEDs. For DIY user, it depends the LED type you are using, any resistor between 300 ohm to 1.5K ohm should work. Using smaller value resistor, you got brighter LED but the PICKit 2 will consume more electric current.

1.7 PICkit 2 I2C EEPROM for Programmer-To-Go (PTG) feature
PICkit 2 supports 128K byte of I2C EEPROM and 256K byte of EEPROM. Default is 128K byte of EEPROM, customer can upgrade to 256K byte of EEPROM by replace the 2 pieces of 24LC512 chipsets with 24LC1025. There is some hardware change on pin A2 between 24LC512 and 24LC1025. For DIY user, Figure 10 illustrates a hardware design to be compatible with both 24LC512 and 24LC1025. With 24LC512 on board, R38 and R39 provide pull-down connection. With 24LC1025 on board, R40 and R41 provide pull up connection. 24LC512 and 24LC1025 are exclusive, same it true for the pull-up (R40 and R41) and pull down (R38 and R39) resistors.

R8 and R9 provide pull up for I2C bus. PIC18F2550 store data to I2C EEPROM by SCL and SDA connection. With the on board EEPROM, the PICKit 2 can program PIC microcontrollers without a PC.

1.8 PICkit 2 ICSP interface
Two types of ICSP interfaces are used in Microchip programmers: RJ12 6p6c connector (Figure 11-a), and 6-pin female header (0.100" spacing) (Figure 11-b). Functionally, they are identical and each has its own pros and cons. The error-proof RJ12 connector using spring contacts to compensate the worn out on pins, it is relatively expensive and takes more space on circuit board. The 6-pin female header takes less circuit board space, but there is limit compensation for pin/contact worn out and there is no mechanism to prevent backwards connection. The RJ12 connector is used in ICD2, ICD3, and RealICE. The 6-pin female header is used in PICKit 2 and PICkit 3. For DIY user, either 6-pin female header or RJ12 connector can be used. For high quality purpose, the RJ12 connector is recommended.

Pogo pin technology (Figure 11-C) can be used to extend the connector life for RJ12 connector and 6-pin header, it is highly recommended for heavy duty usage or manufacturing environment.

The ICSP signal definition on programmer side between the RJ12 6p6c connector and the 6pin female header is opposite. This situation can be easily solved by using different ICSP cables. For ICD2, ICD3, and RealICE, a RJ12 standard cable (Figure 12) is normally used. To be compatible with any circuit board developed for ICD2, a RJ12 reverse cable (Figure 12) can be used with Au Group Electronics developed BB0703 product family.

How to manually update BB0703(PICkit 2) Operating system?

2009-04-23T22:38:00.017-04:00

Author: Chaonan Chen, Huihui Duan, Au Group Electronics

There is very few opportunity ever since the PICkit 2 V2.4x release for a PICkit 2 losing a OS. However it still happens from time to time even in a very very small possibility. When this is happening the PICKit 2 will blink the red LED indicating there is no functioning OS. To get the PICKit 2 back to normal, a new PICkit 2 OS needs be manually downloaded into the PIC18F2550 chipset.

The following tutorial is a step by step guide on how to manually upgrade the PICKit 2 OS. It also answers the following frequent asked question.

Question Asked:
What does it mean when the Busy LED (on PICKit 2) flashes once per second without pushing and holding the button while BB0703 is connected to a USB? How do I correct this?
Answers from Au Group Electronics:
The Busy LED blinking means the unit is in the bootloader mode. For a normal unit, pushing and holding the button while connect BB0703 with USB will manually force the BB0703 (PICkit 2) entering bootloader mode.
To bring the BB0703 (PICkit 2) back to normal programming mode, PICkit 2 Operating System needs to be downloaded from the “PICkit 2 programmer” software. Here is the step by step instruction:
Step 1. Disconnect BB0703 with PC if it was connected before.
Step 2. Open PICkit 2 application software.
Step 3. Connect BB0703 with PC.
Step 4. On "PICKit 2 programmer software", select "Tools-->Check Communication"
"The PICKit 2 has no Operating system. Use the Tools menu to download an OS." will display (figure 1) and the software will be locked up.

Step 5. Disconnect BB0703, this will unfrozen the software.
Step 6. Connect BB0703 back to PC, then click "Tools-->Download PICkit 2 Operating System" (Figure 2)

Step 7. Select the file name "PK2V023200" (assuming V2.61 is used. for other V2.xx, file name should be similar), click OPEN (figure 3)

It will then automatically download the OS into BB0703 (PICKit 2), wait the unit finish the downloading process.

Step 8. Click "Tools-->Check Communication", now it should back to normal mode.

In the V2.5x and V2.6x firmware, there is a self-test safety check feature, if something found wrong on firmware and configuration bits, the unit will be forced entering the bootloader mode thereafter.

A few searches on Microchip Forum provides more background information as the following link.

It is a good practice to leave the unit on the USB port whenever possible.

Au Group Electronics
Author: Chaonan Chen, Huihui Duan, Au Group Electronics

This application note use a dsPIC30F2010 (28-pin SDIP package) demonstrate step by step operation on how to use Au Group Electronics "3-in-1 mini-Lab" and "BB0703" to burn program/code into the dsPIC30F microcontroller.
What you need:
Major devices that were used in this application note and their Au Group Electronics part # are listed in table 1.

There are two methods to load hex file into target chipset: programming with a PC or Programmer-to-Go. This application note will show both methods.
Program dsPIC30F2010 with a PC:
If hex file has not been burned into BB003 (PICkit 2) programmer, a PC is needed. The hardware setup of Programming with a PC would be similar like figure 1.

Step 1. Connect 3-in-1 mini-lab, BB0703 with a PC by RJ12 6Pin reverse cable and type B USB cable.
Step 2. Place a piece of dsPIC30F2010 into the 3-in-1 mini-Lab DIP ZIF socket
Note: Only place one chip at a time. E.g. either put a SOIC packaged chipset in SOIC-ZIF socket; or put a DIP packaged chipset in DIP-ZIF socket. Make sure Pin 1 of dsPIC30F2010 agrees with the 1st-pin-mark on circuit board.
Step 3. Use 9 pieces of female jumper wires to connect J1-x to JZ-x on 3-in-1 mini Lab. The position of both ends of the female jump wires are color coded in Table 2.
Note: J1 (J1-1, J1-2, J1-3) are the extension pin headers for RJ12 6P6C connector
JZ-x (JZ-1 to JZ-6) are the extension pin headers for SOIC and DIP ZIF socket.

ICSP signal on J1 and dsPIC30F2010 are illustrated in figure 2 for reference

Step 4. Double click shortcut of “PICKit 2 V2.6” to open a "PICkit 2 Programmer", Make sure “PICkit 2 connected, and it’s displayed in the message window, and PIC Device (dsPIC30F2010) found, as shown in figure 3.

For programming multiple chipsets, Programmer-to-Go will be another convenient and productive solution. It will be demonstrated at the following steps.
Programmer-to-Go (Programming without a PC)
Step 1. Refer to BB0703 (PICkit 2) PTG application note for how to import and download hex file into BB0703 (PICkit 2). After that, PC is not needed for programming microcontroller.
Step 2. Connect the BB0703 with 3-in-1 mini-Lab using a RJ12 reverse cable.
Step 3. Power up BB0703 with +9 V DC supply, as shown in figure 8. The "Target" LED will blink indicating it's ready to program target chip.

Step 4. Load dsPIC30F2010 into ZIF socket.
Step 5. Press "Program" button on BB0703 (PICkit 2), "Busy" LED will be constant on,
Step 6. Wait a few seconds/minutes, until "Busy" LED is off and "Target" LED blink again, which means the hex file has been burned into the target chipset successfully.
Step 7. Repeat steps 4-6 for programming another dsPIC30F2010 chipset

3-in-1 mini-Lab Application Note for dsPIC33FJ64GP802

2009-03-19T16:09:00.024-04:00

Au Group Electronics
Author: Chaonan Chen, Huihui Duan, Au Group Electronics

This application note uses a dsPIC33FJ64GP802 (28-pin SOIC SMD package) demonstrating step by step operation on how to use Au Group Electronics "3-in-1 mini-Lab" and "BB0703 programmer" to burn program/code into a dsPIC33F microcontroller.

(Note: Experiences found that the VDD level on BB0703 (PICkit 2) is very critical for programming dsPIC33F family microcontrollers, without set it correctly might result in program/erase/blank-check failure. Due to design/engineering tolerance, it is noticeable that the actual VDD voltage on each individual BB0703 (PICkit 2) devices can vary up to 0.1V while programming.)

What you need:

Major devices that were used in this application note are displayed in figure 1, Au Group Electronics part # of the devices that applied in this application note are listed in table 1.

There are two methods to load hex file into target chipset: programming with a PC or Programmer-to-Go. This application note will show both methods.

Program dsPIC33FJ64GP with a PC:

If hex file has not been loaded into BB0703 (PICkit 2) programmer, a PC is needed.

Step 1. Connect 3-in-1 mini-lab, BB0703 together with a PC by a "RJ12 6Pin reverse cable" and a "type B USB cable".

Step 2. Place a piece of dsPIC33FJ64GP802 into the 3-in-1 mini-Lab SOIC ZIF socket

Note: Only place one chip at a time. E.g. either put a SOIC packaged chipset in the SOIC-ZIF socket; or put a DIP packaged chipset in the DIP-ZIF socket. Make sure Pin 1 of dsPIC33FJ64GP agrees with the 1st-pin-mark on circuit board.

Step 3. Use female jumper wires to connect "J1-x" to "JZ-x" on the 3-in-1 mini Lab. The position of both ends of the female jump wires are color coded in figure 2.

Note: J1 (J1-1, J1-2, J1-3) are the extension pin headers for RJ12 6P6C connector
JZ-x (JZ-1 to JZ-6) are the extension pin headers for SOIC and DIP ZIF socket.
ICSP signal on J1 and dsPIC33FJ64GP802 are illustrated in figure 3 for reference

The hardware setup of Programming with a PC is shown in figure 4.

Step 4. Double click shortcut of “PICKit 2 V2.6” (Figure 5)

Step 5. A PICkit 2 Error message may or maynot show up (figure 6). Click “Ok” button. "PICkit 2 Programmer" window open up, PICkit 2 connected and ID displayed but No Device Found, as shown in figure 7.

Step 6. On 3-in-1 mini Lab, use a piece of female jump wire to connect "J3-pin 6 Cap" with "JZ-4-Pin 20", and another jump wire to connect "J3-pin 1 (Pull up)" with "JZ-2-pin 1". The overall jump wire connection on 3-in-1 mini-Lab is shown in figure 8.

All the jump wire connection on 3-in-1 mini-Lab and the signal on both ends are summarized in table 2

Step 7. On PICkit 2 programmer software interface, Click Tools/Check Communication (figure 9).

Step 8. Notice that PIC Device found, and dsPIC33FJ64GP802 displayed. Lower VDD from 3.3 to lower range (between 2.7V to 2.9V)*, and check VDD On, then click “Erase” button (figure 10-1).

* Note:

Base on the multiple devices test (see attached test results for more information, it is provided for reference purpose only), Au Group Electronics noticed that as long as the actual VDD-GND voltage (at device end) falls into the range from 2.74V to 2.91 V, the dsPIC33FJ64GP can be programmed very reliably. If VDD voltage is less then 2.71V or higher than 2.94V, it might not working as reliable as the [2.74V, 2.91V] zone. When the voltage is out of [2.74V, 2.91V] zone, it may indicate “Program memory is not blank” (Figure 10-2) while "blank check" button is clicked, or indicate “Programming of Program Memory failed” (Figure 10-3) while "write" button is clocked. So always try 2.7V, 2.8V, and 2.9V on individual BB0703 (PICkit 2) until programming successfully (this will make sure the VDD at chip end in the user-friendly [2.74V, 2.91V] zone).

If the device in the ZIF socket are not auto-detect, Click "Programmer->Manual Device Select", make sure the checkmark before "Manual Device Select" is gone (picture not show).

Step 9. Wait a few seconds until “Erasing device … Complete”, then click “Blank Check” button, as shown in figure 11.

Wait a few seconds, “Device is Blank” will display, as shown in figure 12

Step 10. Load your target Hex file, then click “Write” button, as shown in figure 13.

Wait a few seconds, message box will display "Programming Successful", as shown in figure 14

For programming multiple chipsets, the Programmer-to-Go feature on BB0703 (PICkit 2) will be another convenient and productive solution. It will be demonstrated at the following steps.

Programmer-to-Go (Programming without a PC)

Step 1. Refer to BB0703 (PICkit 2) PTG application note for how to import and download hex file into BB0703 (PICkit 2). After that, PC is not needed for programming microcontroller.

Step 2. Connect the BB0703 with 3-in-1 mini-Lab using a RJ12 reverse cable.

Step 3. Power up BB0703 with +9 V DC supply, as shown in figure 15. The "Target" LED will blink indicating it's ready to program target chip.

Step 4. Load dePIC33FJ64GP802 into ZIF socket.

Step 5. Press "Program" button on BB0703 (PICkit 2), "Busy" LED will be constant on,

Step 6. Wait a few seconds/minutes, until "Busy" LED is off and "Target" LED blink again, which means the hex file has been burned into the target chipset successfully.

Step 7. Repeat steps 4-6 for programming another dePIC33FJ64GP802 chipset

3. On-board LED test with 6-digit binary LED counter program.
What you need:
All hardware that were used in this application note are listed in table 1.

Major devices are displayed in figure 1 Jumper Wire Connection for Programming:

To burn program into microcontroller, the 6 ICSP connections need to be build between the RJ12 6P6C connector (J1) and the target chipset. On 3-in-1 mini-lab, J1-1, J1-2, J1-3 are the extension pin headers for RJ12 6P6C connector, JZ-x (JZ-1 to JZ-6) are the extension pin headers for SOIC and DIP ZIF socket. The 5 ICSP signal on a few microcontrollers are illustrated in figure 2. Use female jumper wires to connect J1-1 to JZ-x per table 3. The connection is demonstrated in figure 3. There are two methods to load hex file into target chipset: programming with a PC or Programmer-to-Go.

Programming with a PC

Description
The Au Group Electronics PRG0802 is an 8-pin 8-bit flash microcontroller with integrated program. The PRG0802 is a fun circuit for driving up to five LEDs. One push button input will initiate about 15 to 20 seconds of LED “running” activity. Its low current consumption feature makes it also a good candidate for battery-powered toys.

All of the control logic required for circuit operation is contained within the PRG0802 8-pin integrated circuit. Normally only batteries, 5 LEDs, 1 push button switch, and 2 resistors are needed for a completed LED runner circuit.

The PRG0802 drives each LED output in a sequential fashion at approximately 2~3 Hz frequency. With one LED output at a time the current will be maintain at the lowest level.

Pin Descriptions:
The PRG0802 are available in either 8-lead PDIP package (300mil) or 8-lead SOIC surface mount package (3.90mm). Table 1 list the Au Group Electronics part numbers for both packages.

Both PDIP and SOIC package of PRG0802 share the same pin function, it is illustrated in figure 1 and described in table 2.

Pin LED1 to Pin LED5 are five independent LED drivers. The 5 LEDs can be lit by the following 2 ways.
When initially power on,
5 LED lights rotate alternatively from 1 to 5. After LED 5 is on, the next one will be LED 1 again. The 5 LEDs will running in the frequency of 2 to 3 Hz for 15 to 20 seconds, and then enter the low power mode (all LEDs will be off).
During the low power mode,
Press push button SW1 will wake up PRG0802 and start another 15-20 seconds of LED running event.
Each output pin is capable of providing maximum current of 25 mA.

Example:
Figure 2 illustrates a typical connection of a LED Runner circuit system. Battery group B3 could be consisted of 2 to 3 AA type batteries connected in serial. Resistance of R1 should typically be 470K ohm, and R2 should typically be 0 to 300 Ohm. D1 to D5 are LEDs with typical forward voltage of 1.8 to 2.5V. S1 is a push button.

At power on, LEDs keep running for 15-20 second as a self test, then the PRG0802 enters a low power mode.

At low power mode, pressing push button SW1 once will initiate a sequence of LED running for another 15-20 seconds, then it return back to low power mode again. This control strategy is used to detect the switch/button input events and conserve maximum energy for battery applications.

Description
The Au Group Electronics PRG0801 is an 8-pin 8-bit flash microcontroller with integrated program. The PRG0801 is a fun circuit for driving buzzers creating cricket-chirping-like noises and LED blinks at the same time. It has dual input and output interfaces which are independent to each other. It can be used for dual door bell application with LED indications. Also a single door bell circuit can be made if only one door-bell is needed. Its low current consumption feature makes it also a good candidate for battery-powered toys.

All the control logics required for circuit operation is contained within the PRG0801 8-pin integrated circuit. Normally only batteries, 2 buzzers, 2 LEDs, 2 switches, and 4 resistors are needed for a completed dual door bell circuit.

The PRG0801 use a random algorithm to generate chirps/beeps at random intervals up to 8 to 9 seconds. Between these series of chirps/beeps, the integrated circuit is kept at low power mode in order to conserve batteries energy. Also the push-pull buzzer driver is capable of driving non-self-driver type buzzers without external capacitor. It can work with both self-drive type buzzer and non-self-drive type buzzer.

Pin Descriptions:
The PRG0801 is available in either 8-lead PDIP package (300 mil), or 8-lead SOIC surface mount package (3.90mm). Au Group Electronics part numbers for both packages are listed here:
Part #: PRG0801P, 8-lead 300mil plastic Dual In-Line Package (PDIP)
Part #: PRG0801SN, 8-lead 3.90mm body Plastic Small Outlines-Narrow (SN) SOIC
The pin function for both PDIP and SOIC type of PRG0801 is illustrated in figure 1.

Each of the buzzer driver (1 and 2) consists of two output pins (BUZ1-1, BUZ1-2; BUZ2-1, BUZ2-2), the polarity of these two pins is not important. The buzzers and LEDs should be installed in any direction. A resistor should be installed between these two pins to limit the current.

Example:
Figure 2 illustrates a typical connection of a dual door bell with LEDs system. Battery group B3 could be consisted of 2 to 3 pieces of AA type batteries connected in serial. Resistance of R1 and R3 should typically be 100-150 ohm, and resistance of R2 and R4 should typical be 47K Ohm. D1 and D2 are LEDs with typical forward voltage of 1.8 to 2.5V. BUZ-1 and BUZ-2 should be 1.5-5V non-self-drive or self-drive type buzzers. S1 and S2 are push buttons.

• Both buzzers (BUZ1, BUZ2) beeping at a random frequency and a random intervals, and it usually keeps beeping for 8 to 9 seconds
• Both LEDs (D1, D2) flashing at the same frequency and intervals as buzzers, usually for 8 to 9 seconds.
After that, the PRG0801 will enter low power mode if no S1 or S2 events.
At low power mode, the S1 and S2 switch can wake up the PRG0801 and trigger separate events on BUZ1/D1 and BUZ2/D2.
If S1 button is pressed at low power mode,
• BUZ1 keep beeping in a random frequency and a random interval
• D1 keep blinking at the same frequency and interval as BUZ1.
A single push on S1 will keep “buzzer driver 1” circuit on for 8-9 seconds. Then the PRG0801 will be back to low power mode.
If S2 button is pressed at low power mode,
• BUZ2 keep beeping in a random frequency and a random interval
• D2 keep blinking at the same frequency and interval as BUZ2.
A single push on S2 will keep “buzzer driver 2” circuit on for 8-9 seconds. Then the PRG0801 will be back to low power mode.
If S1 and S2 were pressed consecutively at low power mode,
Both BUZ1 and BUZ2 will be on for a maximum period of 8-9 seconds. For instance, while BUZ1 is on, if S2 button is pressed, both BUZ1 and BUZ2 will be on until the first 8-9 second period of BUZ1 is reached. Then, a low power mode will be followed.
This control strategy is used to detect both switch/button input events and conserve maximum energy for battery applications.

1 Introduction
Most of the dsPIC30F microcontrollers have Run-Time Self-Programming (RTSP) capability. New application software code can be upgraded to the chip in field by different communication protocols. The most common communication protocols include: RS232, RS485, SAE-J1708 and Controller Area Network (CAN).

Au Group Electronics dsPIC30F CAN bootloader family includes a serial of bootloader software with different features and capabilities developed for Microchip® dsPIC30F microcontrollers. They are designed upgrading new application software for dsPIC30F chips in field through CAN data bus.
1.1 Six Editions of dsPIC30F CAN Bootloader
Six editions of bootloader are developed for different customer need.
1. dsPIC30F CAN bootloader Compact edition (no encryption)
2. dsPIC30F CAN bootloader Compact Plus edition (with encryption)
3. dsPIC30F CAN bootloader Standard edition (no encryption)
4. dsPIC30F CAN bootloader Standard Plus edition (with encryption)
5. dsPIC30F CAN bootloader Premium edition (no encryption)
6. dsPIC30F CAN bootloader Premium Plus edition (with encryption)

The compact editions are designed for application which has limited memory resource for bootloader. For instance: chips only got 4K words of Instructions Flash Memory. The compact editions require application hex file with manually IVT/AIVT remapped information.
The standard editions are designed for application which has moderate resource for bootloader. For instance: chips got about 24K to 48K words of Instructions Flash Memory.
The premium editions are designed for application which has plenty Flash Memory and want to take advantage of hardware protection on the bootloader section.
Both standard editions and premium editions include the smart IVT/AIVT auto-remapping technology for easy of use purpose, and they support application hex files with or without manually IVT/AIVT remapped information.
All editions have software self-protected technology which prevents them from being erased/damaged by bootloader themselves. The premium edition(s) includes bootloader section hardware protection feature.
1.2 Resource used

Note:
1. Above data is for reference only, it might be slightly different for different chips.
2. The last word of EEPROM is reserved for bootloader, e.g. for dsPIC30F6012A, it's EEPROM address: 0x7FFFFE.
1.3 Major features
1. Code-safety: the Au Group Electronics developed dsPIC30F CAN bootloader implemented Interrupt Vector Table (IVT) and Alternate Interrupt Vector Table (AIVT) remapping technology, which requires no erasing of IVT and AIVT section on any dsPIC30F chipset. This feature will also protect the "Reset-GOTO" instruction from being erased, which will guarantee the bootloader be always "alive" no matter what happened. The whole Bootloader section is also software protected, which prevents it from being erased by itself. Hardware protection on bootloader section is available on all premium editions.
2. Easy use: with the smart IVT and AIVT auto-remapping technology in standard edition and premium edition, the remapping process of IVT and AIVT is transparent for bootloader user. Both merged hex file (which has remapped IVT/AIVT information) and raw-application hex file (which doesn't have remapped IVT/AIVT information) can be used directly for standard edition(s) and premium edition(s). For code size reason, the compact edition doesn’t implement this auto-remapping technology, so it does require manually remapping the IVT/AIVT for each application.
3. Compact edition(s) are available for resource-limited application: Manually remap IVT and AIVT in hex file is required for compact edition(s).
4. Various CAN communication speed available: 500k bps and 250k bps baud rate are available, and other CAN communication speed can be developed per request.
5. Multiple bootloader entering methods available: Hardware trigger method is always available to force chip enter bootloader mode, optional software trigger method (which makes end user bootloading operation a lot easier) is also available.
6. Custom hex file merge service and IVT/AIVT remapping service are available
The above features are summarized in table 2.

1.4 Recommended CAN Network and CAN Transceiver Interface
CAN Network
Rule of thumb to make a reliable CAN bootloading process is: Do not mix different speed CAN nodes in the same network. All CAN nodes in the same network must all run the same speed, for instance 500K bps.
Figure 1 illustrates a typical vehicle CAN network, two 120 ohm terminal resistors must located at each end of the network backbone. An Au Group Electronics BLC-CAN device is used to translate hex data from PC to CAN network. The dsPIC30F microcontroller (MCU) on ECU 2 can be upgrade in field with Au Group Electronics developed dsPIC30F CAN bootloader technology.

Figure 2 illustrate a minimum CAN network with two CAN nodes, which can be used to upgrade dsPIC30F MCU in a lab test environment.

CAN Transceiver
There are many CAN transceivers on the market, to make a smooth integration of Au Group Electronics developed dsPIC30F bootloader technology, hardware designer should secure that the CAN transceiver be default on status at all situation. Demo circuits are illustrated in figure 3a and figure 3b.

2 Bootloader hex code and application hex code
There are some different approaches to implement bootloader code with user application code. The following steps show one quick approach to get bootloading up and running. Following items are required to get started:
1. Application hardware
2. Au Group Electronics developed dsPIC30F bootloader hex code, or a merged hex file which contains bootloader code, application code and remapped IVT/AIVT info.
3. Application hex code with or without manual IVT/AIVT remapped info.
Note: For compact edition(s) user, the application hex code must be manually remapped to have the remapped IVT/AIVT info.
2.1 Step 1: Download bootloader code to MCU
To get bootloading started, the bootloader hex file (figure 4a) or a merged hex file (figure 4b) must be burned into microcontroller through a programmer (e.g. BB0703 (PICkit 2)/ICD2/ PM3, etc.) After a dsPIC30F MCU is burned with bootload hex file, it is cable of updating application code in field thereafter. This step is a one-time operation only.

On this step, using a merged file (figure 4b) which contains bootloader code, application code, and IVT/AIVT remapped info, will save user some time overall because the bootloader code and application code is programmed into the chipset in one-shot. It is extremely important for high volume manufacturing.
2.2 Step 2: Bootloading
When the MCU has the bootloader software onboard, user can download a new application hex file or a new merged hex file to microcontroller through CAN network (figure 5) at any time. An Au Group Electronics developed BLC-CAN device must be used to convert PC RS232 signal to CAN signal.

Note: For compact edition(s) user, the application hex code must be manually remapped to have the remapped IVT/AIVT info.

The standard edition(s) and premium edition(s) of Au Group Electronics developed dsPIC30F CAN Bootloader include the smart auto-map technology which enables user use raw application file without manually remap the IVT and AIVT. The bootloader will auto-sense and auto-remap the IVT and AIVT during bootloading process without human interference. However a manually IVT/AIVT remapped application hex file (for instance, a merged hex file which contains bootloader code, application code and remapped IVT/AIVT info) still can be used.

For the compact edition(s), because of the bootloader space limitation, they don't have the smart auto-map technology, so the re-mapping process of IVT/AIVT must be performed manually and only a hex file with remapped IVT/AIVT info can be used for bootloading.

Both IVT/AIVT manual remap service and hex file merge service are available at Au Group Electronics.
The following chapters will demonstrate on bootloading a hex file through CAN network step by step, also how to merge an application hex file with a bootloader hex file is demonstrated.
3 Bootloading with BLC-CAN device & PIC bootloader program
After a bootloader has been pre-programmed into a dsPIC30F chip, user application code can be upgraded any time thereafter using the BLC-CAN device and the PIC bootloader program from Au Group Electronics.

There are two methods to trigger the dsPIC30F chip entering bootloader mode: software trigger method and hardware trigger method.

Software trigger method:
This method requires integrating special CAN processing code into application software. It is an option feature for application code.
All Au Group Electronics developed bootloader support this feature for easy of use purpose. When this feature is supported, the "Reset PIC" button on "Au PIC Bootloader" software can be used to force the MCU entering bootloader mode.

Hardware trigger method:
Different hardware trigger method can be developed to force MCU entering bootloader mode at power up. For instance, on one of the Au Group Electronics CAN bootloader evaluation board, connect +12V supply to pin 7, unplug the power supply, then plug the power supply back will hardware trigger the MCU entering bootloader mode.

The following steps used software trigger to force application board entering bootloading mode, user can also try hardware trigger method at step 5.
1. On the PC with Au PIC bootloader software installed, double click "Au PIC Bootloader V1.00B" shortcut, as shown in figure 6.
2. Click "Load File" button in "Au PIC Bootloader by Au Electronics 1.00B (Eval Edition) " window, as shown in figure 7.

3. Select an application hex file, e.g. "LedRotate.hex" in this case, then click "Open", as shown in figure 8.

4. File name "LedRotate.hex" display, then select RS232 serial port, set speed at 11520 (figure 9).

5. Click "Reset PIC" button (figure 9) will trigger the dsPIC30F CAN bootloader demo board enter bootloading mode: bootloader LED (D12, as illustrated in figure 10) on demo board blinks, Power LED (D11, as illustrated in figure 10) constant on, all the other LEDs are off. Hardware trigger method can also be used to force demo board entering bootloading mode at this step.

6. Within 10 seconds, click "Connect" button, as shown in figure 9.
7. The connection status ON indicator on PIC bootloader program will turn Green. Also the Bootloader LED (D12) on the demo board will be constant ON, click "Program" button ( figure 11)

8. Flash Erasing and Programming progress bar will be moving as bootloading proceed, a long beeping on PC indicates bootloading accomplished, click "Exit" to close the program, as shown in figure 12.

4 Merge application hex file with bootloader hex file and remap interrupt vectors
Even though for standard editions and premium editions, raw application hex file can be used, it is always convenient for manufacturing to have just one hex image which contains application hex code, bootloader hex code and have the IVT/AIVT remapped. The following paragraph will show one method on how to merge the application hex file with bootloader hex file step by step.
4.1 Merge application hex file with bootloader hex file
The merging process is accomplished by using Microchip® MPLAB IDE.
1. Double click shortcut of "MPLAB IDE" to open MPLAB, as shown in figure 13
2. Click Configure/Select Device…to open select device window, as shown in figure 14.

3. In "Select Device" window, select the chip from the Device dropdown list, dsPIC30F6012A is showing here for example, then click OK button (figure 15).

4. Click Debugger/Clear Memory/All Memory to clear all memory in microcontroller, as shown in figure 16.

5. Click Configure/Setting…, as shown in figure 17.

6. Click "Program Loading" tab, make sure "Clear memory before building a project" is selected, and "Clear program memory upon loading a program" is unchecked, click "Apply", then "OK", as shown in figure 18.

7. Click "View/Program memory" (figure 19) to open up "Program Memory" window.

8. In the Program Memory window, click "PSV Mixed" or "Machine" or "Symbolic" tab, the "Opcode" should be "FFFFFF" in all Address, as shown in figure 20.

9. Click File/Import… (Figure 21) to import application file.

10. Select your application hex file (myproject.hex file is showing here), then click "Open", as shown in figure 22

11. Check the Opcode from address 00004 to 0007E (address for IVT), and address from 00084 to 000FE (address for AIVT), write down all Opcode contents which are the interrupt vector address for each interrupt. They will be the address to be remapped after importing the bootloader hex file.

In the following example, most of the Opcode contents from address 00004 to 0007E are 000000, except for the Opcode at address 0001A is 001042, as shown in figure 23

All the Opcode contents from address 00084 to 000FE are 000000, except for the Opcode at address 0009A is 001042, as shown in figure 24

12. Click File/Import… (Figure 25) to import Bootloader hex file.

13. Select a Bootloader hex file, then click "Open", as shown in figure 26. Au Group Electronics developed hex file "dsPIC30F6012A_CAN_Bootloader_6¬_5MHz_with_Encription.hex" is showing here for an example.

14. Notice that the Opcode content for address 0001A is 000E2C after importing Bootloader file (figure 27).

4.2 Manually Remap Interrupt vectors
Following steps use 0001A as an example to demonstrate how to manually remap the interrupt vectors to a new location.
1. In line 14, right click 000E2C of address 0001A to open a drop down menu, then click "Go To…" to open a "Go To" window, as shown in figure 28.

2. In "Go To" window, enter the Opcode hex address at address 0001A: 0X000E2C, then click "Go To" button, as shown in figure 29a, curser go to line 1815 address 00E2C, as sown in figure 29b.

3. Double click nopr in the line of address 00E2C, change nopr to "goto 0x001042" (figure 30).

4. Notice the change for the line at address 00E2C and 00E2E (Figure 31):
Opcode of 00E2C change from FFFFF to 041042, disassembly showing goto 0x001042
Opcode of 00E2E change from FFFFF to 000000, disassembly showing nop

The above steps showed how to remap Time1 interrupt vector (0x0001A) step by step, for other interrupts, please repeat above steps 1-3.

Hex file merge service is available at Au Group Electronics.
5 Microchip C30 application software development
5.1 Integrate Bootloader software trigger method into application C source code
Software trigger method is always supported by all Au group Electronics developed bootloader products for easy of use purpose. However this feature requires user integrating the following function into application software.
Note: This is an option feature; user doesn't have to integrate it into its application software when resource is limited.

1. Setup the CAN module in MCU with correct speed and filters
2. Monitoring incoming CAN data and save all CAN2.0A data from ID 0x0FD (which should have been reserved for the Au Group Electronics BLC-CAN device on a CAN network)
3. When a AT command string is found as: “AT BTLD RST \r\n”, execute the following two command in sequence:
a. Write "0XA55A" to EEPROM address "0X007FFFFE",
b. Issue a "Reset" instruction
After the MCU issued a reset instruction, the bootloader should be able to take over and force the chip entering bootloader mode for 10 seconds. This is a one-time only operation.
5.2 Configuration bit setting in application software C source code
User can set up configuration bits in C source code, the following code gives a working example.

#include
_FOSC(CSW_FSCM_OFF & XT_PLL16);
_FWDT(WDT_OFF & WDTPSA_512 & WDTPSB_1); //WDT must be disabled here and enabled by application software.
_FBORPOR(PBOR_ON & BORV_45 & PWRT_64 & MCLR_EN);
_FBS(NO_BOOT_RAM & NO_BOOT_EEPROM & STRD_MEDIUM_BOOT_CODE & WR_PROT_BOOT_OFF);
_FSS(NO_SEC_RAM & NO_SEC_EEPROM & NO_SEC_CODE);
_FGS(CODE_PROT_ON);
_FICD(ICS_NONE ); //need modify the p30f6012A to make this correct. Original Microchip file messed up.

User may modify above code accordingly to meet specific purpose.
5.3 Watchdog usage in application software C source code
To use minimum resource/overhead and flash memory for the bootloader program, the watchdog in dsPIC30F chips is require to be controlled by the SWDTEN bit in application software, the following example demonstrate one method to use watchdog in a application software.
1. Click View/Project in MPLAB to open project window, as shown in figure 32

2. Double click *. C file under source files (myfile.c is showing here for example, figure 33).

3. Set up the watchdog configuration bits in your .C file:
#include
……
_FWDT(WDT_OFF & WDTPSA_512 & WDTPSB_1);
……
4. In the initialize code, enable watchdog:
void initialize(void) {
……

_SWDTEN = 1; //enable the wdt
…… }
5. Clear watchdog in the main loop:
int main (void){
initialize(); //initialize port and variables.
while (1) {
….
ClrWdt();
….
}
return 0;
}
5.4 Application software Linker Script setting (for Microchip C30 users)
Since bootloader takes the reset vector, the starting address of the application software must be remapped in the linker script for Microchip C30 as following:

A project named myproject.mcp and a dsPIC30F6012A chipset has been used for demonstration purpose.

1. Click "View/project" to open myproject.mcw window, double click "p30f6012A.gld" under linker Script (figure 34, note: different chip will have different ***.gld file)

Note: the best practice is to copy this link script file to your project local folder.

2. In the p306012f.gld file, 3 places (Program ORIGIN, program LENGTH, _CODE_BASE) will be changed to 0X1000 for Premium edition(s), as shown in figure 35 and figure 36.
Note:
1. The changes are for premium edition(s) only.
2. For Standard edition(s), 0x0E00 is used. For compact edition(s), 0x0B00 is used. Au Group Electronics reserve the right to change these numbers for different application and customer requirements. It is a good practice to contact our technical support for specific chip application.

6 Encrypted edition(s)
Au Group Electronics provides custom designed "Hex Encoder" software program for each individual customer who purchased bootloader products with encryption feature.

Au Group Electronics "Hex Encoder" is a software program which converts non-encrypted hex file to encrypted Aud file with custom designed encryption algorithm. The encrypted Aud file can be used to upgrade microcontroller's flash memory in-field for any products with Au Group Electronics developed bootloader technology. No non-encrypted hex file will be send to the end user any more!

Note: To use encrypted Aud files, custom made bootloader application software with respect encryption/decryption algorithm is required. Please refer to Au Hex Encoder User Manual for detail information.

f. Programming toolset: a functioning PICKit2 or ICD2, etc. (only required If the PIC18F2550 is not pre-programmed,)

2. Assemble components step by step:
a. Solder all components to the CB0703 PCB board.
Basic sequence for Do-It-Yourself (DIY) hand-soldering:
· From the center of the board to the edge
· From one side to the other side
· From SMD-components to through-hole-components
· From small components to big components

There are two assembly-drawings attached, one can be used for part number reference, the other one can be used for pin numbers reference.

The following pictures illustrate a particular assemble sequence step by step. (Other sequences are possible)

b. Clean all flux residual from the board.
c. Dry the whole assembled board after clean.
d. Visual inspect and verify circuit connectivity (using multi-meter), make sure no short-circuit or open-circuit. Fix all issue if found.
e. Program PIC18F2550 on-board by using ICD2 or another PICkit2 as following:
i. Power up the board by USB or dedicated power source if the enhanced power supply circuit is installed.
ii. The Hex of “PK2V021000.hex” or a hex-file in similar name should be found under folder “C:\Program Files\Microchip\PICkit 2 v2”. Import this hex file to MPLAB or any other programming tools you are using.
iii. Program the PIC18F2550 Chipset by ICD2 or any other functioning PICkit2.

A 5-position program-pad is designed on CB0703 for ICSP connection (In Circuit Serial Programming) from ICD2, PICKit 2 or any other ICSP programmers.
Note:
1. If a pre-programmed PIC18F2550 chipset is used, it is not required to program the PIC18F2550 again.
2. If there is no *.hex file found, send an email to Au Group Electronics to request.
3. If there is no ICD2 or any other ICSP tool available, you need purchased at least one pre-programmed PIC18F2550 chipset (part#: PPIC18F2550) from Au Group Electronics (http://www.auelectronics.com/Hardware-CB0703.htm).
After the last step, the whole board should start functioning.

Can BB0703 (PICkit 2) work with board designed for ICD2?

2009-02-04T19:26:00.005-05:00

Author: Chaonan Chen, Au Group Electronics
The Au Group Electronics BB0703 can work directly on target board designed for ICD2 with a RJ12 6-pin reverse cable (Part#:CBL-RJ12-RVS).

Note: The BB0703 (PICkit 2) is designed based on the Microchip-recommended-schematic. So the BB0703 (PICKit2) RJ12-Connector ICSP- pinout-sequence is reversed comparing with ICD2.

The following table (table 1) shows the RJ12 connector pin-out of Microchip ICD 2 and BB0703 (PICkit 2):

Table 1

Pin number	MPLAB ICD2 RJ12 Connector Pin-out Signal	BB0703 (PICkit 2) RJ12 connector Pin-out signal
1	Not used	MCLR/Vpp
2	PGC	VDD
3	PGD	Ground
4	Ground	PGD
5	VDD	PGC
6	MCLR/Vpp	Auxiliary

The reversed signal doesn't prevent BB0703 from being compatible with ICD 2, a RJ12 6-pin reversed cable can be used to connect BB0703 with any target board designed for ICD2 (as show in Figure 1).

Figure 1

Both RJ12 6-pin standard cable (Part#:CBL-RJ12-STD) and RJ12 6-pin reverse cable (Part#:CBL-RJ12-RVS) are available here at AU group Electronics.

How to identify the pin number on SMD packages?

2009-02-04T11:00:00.009-05:00

Author: Chaonan Chen, Au Group Electronics
The article used some components from Au Group Electronics BB0703 to illustrate how to identify the first pin or the pin polarity for SMD chips, capacitors, LED, and diodes etc.

U1 is PIC18F2550, there is a "dot" mark on the chip and pin 1 is on the left side of the mark.

U3 and U4 are 24LC512 EEPROM, identify the "dot" mark on the chip, and pin 1 is located on the left side of the mark.

U5 is LM317L, U6 is FDC6420C, both chip has a "dot" mark next to the pin 1.

C15 is an aluminum electrolytic capacitor, there is a black mark on the top of the capacitor which represents the "negative side" of the capacitor.

C5, C12 and C14 are tantalum capacitors, the black mark on the top of the capacitor package represents the anode (positive termination) of the capacitor.

The SMD LEDs have a color make on the cathode (Negative termination).
The through hole type LED has a shorter pin which represents cathode (negative termination).

D5 is diode S1G, which has a mark on the cathode (Negative termination).

D100 is 1N4148, which has a mark on the cathode (Negative termination).

What tools do I need for soldering components to PCB?

2009-02-04T10:40:00.008-05:00

Author: Chaonan Chen, Au Group Electronics
The tools may be needed for manually soldering components to printed circuit board (PCB) are illustrated below (there might also be some other approaches available, such as hot plate, hot air, hot oven, etc.):

1.Solder station with a 25W to 30W soldering iron.

It would be good to have at least two soldering iron for re-work purpose. For instance, to de-solder some SMD components with two pads, such as: SMD resistor chips, SMD capacitor, and some SOIC chips, it would be fairly easy to use two solder iron heating both side of the pads at the same time for fast components removing. To de-soldering some TQFP chips, it would be good to have four soldering irons for rework purpose.

You can get solder irons and solder station from local stores such as: Wal-Mart store, Sears, Radio Shack, Ocean State Job Lot, etc. Some decent solder iron with station (such as a Weller WESD51) may cost as high as a few hundreds US dollars. For Do It Yourself purpose, you can find a good solder iron with station in a price range of 4 to 10 US dollars at local stores.
If price is not an issue, an temperature adjustable solder iron is recommended.

2.Tweezers

Fine points, 4.5" long, anti-magnetic Tweezers are highly recommended for SMD components handling. For instance, some resistors and capacitors are in a 0805 type of package, a tweezers will help a lot for pick them up and put them on the right position for soldering.
Tweezers are available at various local stores, also you can find them on online stores, such as ebay, Allied Electronics, etc.

3.Magnifier
A 2x to 10x magnifier is used to inspect circuits. A full inspection of the circuit board is highly recommended after all components are assembled and the circuit board is cleaned. The magnifier can let you have a good visual-inspection on possible flux residual, solder short-circuit or open circuit issue before the power supply is connect to the circuits. Magnifiers are available at various hobby store or hand-craft department of giant retail stores. Also some online retailers such as Jameco carry some decent portable magnifiers.

4.Solder
A 25 AWG or finer solder with flux core is highly recommended. Kester has a full family of solder for traditional and lead-free application. For Do It Yourself fans, a solder wire with water-soluble flux core is highly recommend for easy clean purpose. Solders can be ordered through local store like Radio Shack or online store like DigiKey, etc.

5.Liquid flux (solder paste) and brush

Liquid flux and solder paste can help the solder forming a quick and smooth joint with PCB pads.

A brush can help distribute the liquid flux to PCB pads or components pins. Water-soluble liquid flux is recommended for easy clean purpose. A Kester water soluble 2331-zx flux pen will meet most do it yourself requirement, and is available through many online stores like Digikey.

6.Residual cleaning tool

After the circuit board is fully assembled, all flux residual must be cleaned. An used toothbrush can serve this purpose very well.

So, save your used toothbrush and enjoy the process and happiness of Do It Yourself (DIY).
