Hi All,

Can anybody suggest a  Modbus Library for DSPIC30F4011 Microcontroller.

It is for a DSPIC30F4011 based Slave. Master will be an HMI.

Thanks and Regards

Freemodbus have an example for PIC32. But I don't know if the implementation is for both Master and Slave devices.
If you know, please let me know.
Probably I will have to use it (in Master mode) in the near future, but I will use a PIC18 or PIC24.

There is another implementation called "SimpleModbus" for Arduino. They have code for Slave mode. You may use it to adapt the code for the dsPIC:

IIRC I saw some MODBUS libs with sources at http://www.libstock.com.
Just search for keyword MODBUS.

Your post only replies to my previous question: This implementation is only for slave mode.
Apart from that it is just a link to a page with a link to an old version of Freemodbus stack (v1.4).
Current version is v1.5.
