2 Arduinos talk to each other over RS485
-
Hello people. Try as I might, I can not find a simple example sketch for arduino-a to talk to arduino-b over serial and using RS485 ttl adapters. Surely it must be simpler than I keep hearing. Has anybody please got simple sketches for arduino-a (sender) and arduino-b (rcvr). thank you thank you thank you. pj :hugging_face:

Examples are there too.
( MySensors uses this code for 485 transport layer too )
Or another very simple example:
