2 Arduinos talk to each other over RS485

[redcarpet]

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

I have it up and running, you have to send the value from node A to node B directly

Here is a topic about it

Examples are there too.

( MySensors uses this code for 485 transport layer too )

Or another very simple example:
