The Arduino RS485 library enables you to send and receive data using the RS-485 standard with Arduino® RS485 Shields, like the MKR 485 Shield. Please refer to the MKR RS485 Shield documentation for the specific settings about half, full duplex, and termination.
This library supports the MAX3157 and equivalent chipsets.
To use this library:
#include <ArduinoRS485.h>
