Requirements

Hardware

  1. PC with COM port (Windows XP Installed for MPLAB)
  2. ICD2 Programmer
  3. Target Board
  4. 5V Power Supply

Software

  1. MPLAB IDE v7.50: v7.60 is not compatible with our current ICD2 Programmers. There are consistent "Devices cannot be founded" warnings.
  2. dsPicProgrammer (dsPicProgrammer.jar)

Files

  1. dsPicBootloader (bl_5011.hex). Original assembly code by ingenia can be downloaded from here.
  2. Application hex file (e.g. app.hex)


Loading Bootloader (Once only)

Loading Bootloader
Step Remarks
Install MPLAB IDE
  • Do NOT connect ICD 2 (via USB) to PC
  • Execute MPLAB vX.XX Install.exe
Install USB Driver
  • Follow the instruction in (C:\Program Files\Microchip\MPLAB IDE\ICD2\Drivers\Ddicd2.htm)
Select Target Chip
  • Run MPLAB IDE on PC
  • Select: Configure>Select Devices...
  • Choose dsPIC30F5011
Target <-> ICD 2
  • Use six pin cable. Beware of the pin assignments. Only pin 1 - 5 should be used.
  • Place Jumper on target board (if any). The Jumper connects target Vcc to ICD 2.
  • Do NOT power-up the target.
ICD 2 <-> PC
  • Plug-in ICD 2 to PC via USB cable
  • Power-up the target.
  • Select: Programmer>Select Programmer>MPLAB ICD 2
  • If this is the first time the ICD 2 is connected to PC, MPLAB IDE will automatically download the required OS to ICD 2, wait until it has finished
  • If you have not connected and powered up the target, you might see Warnings on invalid device IDs, and/or running self tests.
  • See results of self test if necessary: Programmer>Settings, Status Tab. Refer to ICD2 User's Guide Chapter 7.
Load Bootloader
  • Select: File>Import...
  • Select bl_5011.hex
Start Programming
  • Select: Programmer>Program
Finishing
  • Power-down the Taget
  • Select: Programmer>Select Programmer>None
  • Unplug USB cable


Loading Firmware

File:Dl zip.JPG

  • Unzip the dsPic_Programmer.zip, then you have unziped file.

  • Drap the unzip file to a director.
eg. USB memory devics

  • Save your .hex file(foo.hex) to your directory location (e.g. C:\dsPicProgrammer\)
    • [Save to your hex file PIC]

Download Firmware

  • Start a Command Prompt
  • Run dsPicProgrammer
    • Make sure your device is connected through a "Direct RS232 Cable" to PC Serial Port.
    • Change to the directory where dsPicProgrammer.jar is located and run the command:
      • [path/to/java/]java -Djava.library.path=[path/to/rxtxlib] -jar dsPicProgrammer.jar COM1 115200 foo.hex
        • for example, jre\bin\java -Djava.library.path=.\rxtx\bin -jar dspicProgrammer.jar COM1 115200 foo.hex
      • Or directly using dsPicProgrammer.bat COM1 115200 foo.hex(Windows)
      • java -jar dsPicProgrammer.jar /dev/ttyS0 115200 foo.hex (Linux)
where COM1 is your COM Port ID
115200 is communication speed [in bps]
foo.hex is your firmware new file
