- 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)
- [path/to/java/]java -Djava.library.path=[path/to/rxtxlib] -jar dsPicProgrammer.jar COM1 57600 foo.hex
- where COM1 is your COM Port ID
- 57600 is communication speed [in bps]
- foo.hex is your firmware new file
- When the program prompt you for an input, press y:
