I already got stuck on it for few months. Can anyone show me the Modbus RTU souce code in PIC ASM file? I tried for so many kinds of ASM file but it didn't work in my IC. PIC877A.

I have ask for all the friends that I know, but they have no idea how to do it, so last idea is ask help here, hope that someone can help me out.

Thanks for all~~!

I have a Modbus routine for the 16F876/7 series of microcontrollers - let me know your e-mail address and I'll send you a copy.

Hi Bruce, two questions:

(1) Could you also send me a copy of the code?
(2) Can ModBus work with a Pic16F628 chip?

Thanks,
Roger

Hi Roger, Scott,
Roger, I will need an e-mail address. I cannot see offhand any reason why the routine won't work with the 16F628 - it will depend on how much info you need to transfer which controls how much data buffer space you need.

Scott, I tried the address you gave but the message bounced. Try contacting me via bmd1urdle a2t cle3ar d4ot net nz without the digits.

Cheers,
Bruce.

Hi Jorge,
Either contact me direct at the e-mail address I gave or let me have your e-mail address via the list - I cannot send enclosures via the mailing list.
