x2 Esp32 ModbusMaster Arduino IDE Postby girasera » Thu Jul 09, 2020 2:48 pm Hi everyone, I'm trying to do ESP32 communicate with a Freq. Inverter using MAX485 converter. I'm using the library ModbusMaster with Arduino IDE. I tested a Arduino UNO instead the ESP32 and it worked fine. With the ESP32 I can only write to the Inverter, but not read.ESP32 can work with any devices/software that uses Modbus. When should use and should NOT use Modbus Because the Modbus protocol is not easy to understand and implement it, even the Modbus library is available. You can use a simple self-defined protocol as described above when:SensorModbusMaster. Arduino library for communicating via modbus with the Arduino acting as master.
