      Does anyone manage to have a working modbus communication with the M5station-485
      I use to work with the industrialshield modbus library : https://github.com/Industrial-Shields/arduino-Modbus
      I do manage to use it with the atomhub-switch using serial2 with RX and TX on 33 and 23.

      For this board the RE/DE pin should be controlled but I do not know where to configure it!

      Any help is welcome :)

        maybe this example I wrote a while ago could be helpful?

        Thanks
