Bidirectional Serial Communication between two Arduinos

Greetings everyone. I have found XOD a week ago searching for a visual programming IDE for microcontrollers, like Arduino. I am working on a project of a PLC to give a “brain” to some machines. So I need to work with two microcontrollers together. The first one will have an application for machine control, reading, processing, and writing data (much better XOD than C++ for that), and the second will have its GPIOs connected to field interface electronic circuits (reading and writing data). …

Read Serial UART for Talk-Back, Command Processing, Troubleshooting

Below is an example of Serial Com from the Computer to UART-0 (Mega) collecting the command and sending it back while printing it on a 16x2 parallel LCD. Overall, it works, but I feel it’s clunky, it could miss consecutive commands, and could be better written in the cpp not-implemented-in-xod node. Serial communication is still required for some applications, particularly in the science industry. Typically, a the computer sends a serial message to the unit, and the unit responds and sends a me…
