Hi,
I would to use RS485 for my interfacing between PC and few other serial module.
What's the step should i start on the Hardware and Firmware(Protocol) side?
Example I had 3 node (node1=PC, node2=MCU1, node3=MCU2).
My PC only had one serial RS232 port, and the MCU also only had one serial. If i would like to use standard RS232 for all the node in interface, so i just have to put a RS485-RS232 convertor? If yes, how the node recognize the protocol?
Did anyone have a simple sample code for RS485? I just want to get some idea. I had no problem with using RS232.
Thank You.
