Modbus stack for Microchip PIC

Question

Can someone suggest an open source implementation of a Modbus RTU Slave for a Microchip PIC18 processor? I\'m looking for an implementation of Modbus RTU for RS-232/RS-485,

Answer 1

Solutions seems limited. There a example code at www.sourceboost.com which is freemodbus port targeting their compiler. Also porting Freemodbus on your own to a PIC18 should not be to hard. I have used the free mod bus library without any problems on larger processors and I see there is AVR ports so a PIC port should be possible.
