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).
I need to establish serial communication between the Arduinos to do that. We can simulate with LEDs and pots like Mr. Gabbapeople’s example “gabbapeople/uart-led-control”. (Fantastic job).
Another tutorial was given by Mr. Max Danilin with “https://medium.com/@gpeople/simple-uart-communication-protocol-in-xod-9ce67cc69d3c”
I think the solution presented by Mr. Max fits better for my project (packets of data with checksum), but I have a question:
How to send and receive data for both Arduinos? One to the other. Like Mr. Gabbapeople’s example have the same configuration, but 1 LED and 1 pot in each Arduino.
I think it can be solved using flow control like Mr. Jan Mallari’s example: “How to Set Up UART Communication on the Arduino - Circuit Basics”.
But how to do this in XOD ?
I appreciate any help
