Good morning to all and excuse my English, I'm Brazilian. I would like to know if anyone knows if it is possible to communicate via serial modbus using rs-485 with arduino due. If so, which library and IDE should I use. I have serial modbus running in the mega and uno, but until now I could not use with the due.
Maybe this thread which solves an important issue with implementation of Modbus RS485 for Arduino DUE will help you, from reply #10:
