Raspberry Pi Forums

Hi,

did any try the libmodbus library on the raspberry pi.
I wrote a slave program, this woks. I just have some problems to work as a master.

Has anyone a living example code?

I use it a lot to control some build-in I/O remote . Works like a charm in master mode if you are using an USB to RS-485 adapter.

This is the post.

This is the github. You will have some code on my github. Check 'configPIC.c'. I use libmodbus on it.
