hi, i am trying to interface with a 3 phase modbus controlled motor using the arduino MKR WIFI 1010 and the MKR 485 modes shield. can someone help me of how to get started please ?
Use one of the available Modbus master libraries for Arduino, connect the RS485 bus of the two devices and set the Modbus registers according to the manual. If you get problems, post the code you're trying with and the output you get, we will try to help you. Don't expect us to write the code for you.
