Hello, I have a question about wiring connection between multiple Arduinos MEGA 2560 and RS485. I am not much aware of Arduino. I want to make 6 arduinos communicating with each other using RS485. So how the circuit connections should be ? Can anybody please suggest me ?
Thanks in advance.
Normally, with TIA-485 data interface, there is a master node which initiates communications on the TIA-485 network bus. What data protocol are you thinking of using ?
Here is a good tutorial w/ libraries. RS485 communications
