I want to develop Modbus communication in real electrical devices system. I have done 1:1 communication using Modbus and I also have wrote Master and Slave library for this 1:1 RS485 Modbus communication. But I want to extend this Modbus Communication 1: 10 at least. Theoritically using Modbus communication we can extend 1: 256 Modbus communication. But I jsut want to develop only 1: 10 Modbus communication. You need to develop 1:10 communication Modbus Master and Slave library and make these real.
Master is an Arduino Mega and Slave is a Arduino Uno. If you have experience, this will be great.
