Hi, I have a project in making a Master-Slave Modbus Communication with RS485 using ArduinoIDE. The devices is a WeMos D1 Mini for Slave and a NodeMCU for Master. I use SimpleModbusMasterV2 and SimpleModbusSlaveV10.The code I'm using : Master: #include <SimpleModbusMaster.h> ////////////////////…

Help with WeMos D1 Mini and NodeMCU in ModbusRTU RS485
