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 :)
