  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)

Step Remarks
Install MPLAB IDE
  • Do NOT connect ICD 2 (via USB) to PC
  • Execute MPLAB vX.XX Install.exe

  • 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.

  • Copy RXTXcomm.jar to
    • For Windows users, C:\Program Files\Java\X\lib\ext (under the latest jre, e.g. X = jre1.6.0_03)
    • For Linux users, /usr/lib/jvm/java-version/jre/lib/ext
      1 3 rxtxcomm.JPG
  • Copy rxtxSerial.dll/librxtxSerial.so to

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 57600 foo.hex
        • for example, jre\bin\java -Djava.library.path=.\rxtx\bin -jar dspicProgrammer.jar COM1 57600 foo.hex
      • Or directly using dsPicProgrammer.bat COM1 57600 foo.hex(Windows)
      • java -jar dsPicProgrammer.jar /dev/ttyS0 57600 foo.hex (Linux)
where COM1 is your COM Port ID
57600 is communication speed [in bps]
foo.hex is your firmware new file
