This is a simple class to enable multiple Arduinos to communicate with each other in either a multi-drop RS-485 network, or point-to-point using direct RS-232. Up to 254 stations can be defined, and any one station can send commands and messages to any other station. Messages are in the form of small packets including a header section, data section, and checksum.
Now also includes a C library for Linux to communicate between a PC or Pi and Arduino.
