Hardware Setting
- Connect your usb to rs232 cable to your computer
- Or Using a real RS232 Port -- COM PORT
Download and Loading Firmware
Make sure the RS232 Port in your computer
- Go to Control Panel \ Device Manager
- Find out your Device comm port Number
Get the Dspic Programmer
- Download dsPic_Programmer.zip, updated directory or svn server
- Save to a directory.
- e.g. desktop
- Unzip the dsPic_Programmer.zip, then you have an unziped file.
- Drag the unzip file to a director.
- eg. USB memory devics
- Save your .hex file(foo.hex) to your directory location
- e.g. X:\dsPic_Programmer\ ---> X:\ is the driver where the dsPic_Programmer located
Download Firmware
- Start a Command Prompt
- Start -> Run
File:2 1 run.JPG - Enter cmd
File:2 2 cmd.JPG
- Start -> Run
- 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:
- 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
- When the program prompt you for an input, press y:

- Wait until programming is completed.
- after all completed, power OFF your device, then power ON again, enjoy your new updated.
Troubleshooting
Invalid COM Port
- In case of selecting an invalid COM port, you should see the error message:
gnu.io.NoSuchPortException: Choosing COM Port Error
Missing firmware file
- In case of selecting a firmware file that does not exist, you should see the error message:
java.io.FileNotFoundException: foo1.hex <The system cannot find the file specified>
