Arduino library for communicating via modbus with the Arduino acting as master
This library is designed to use an Arduino as a modbus master to communicate with a sensor/slave via modbus RTU. It's specifically written with lots of "higher-level" functions to help out users who are largely unfamiliar with the modbus protocol and want an easy way to get information from a modbus device.

This library is compatible with the avr, sam, samd architectures so you should be able to use it on the following Arduino boards:

Compatibility Note

Note: while the library is supposed to compile correctly on these architectures, it might require specific hardware features that may be available only on some boards.


To use this library, open the Library Manager in the Arduino IDE and install it from there.
