Have now focused on ArduinoModbus.h and Arduino485.h and am trying to adapt the simplest example by Sandeep Mistry that comes with the library. I have looked at several Modbus examples and libraries but find them very challenging, examples that are not very relevant, in some cases not working or just too difficult to understand. Because of the distance of about 60m and the need for probably one master and five slave boards I assume that Modbus with twisted pair wiring is the only robust solution. ![]() I have successfully completed tutorials on the internet that involve two boards with direct communication using MAX485 TTL converters. I am a Newbie, starting work on a project to drive LED decorative lighting over long distance outdoors. ![]()
