I’m happily taking my project forward thanks to you all and the newcomers guides at the begining of the forum (The "Serial Communication Basics was greeeeat!!!) Now I have a steady and perfect communication between three Arduinos.
The only part that is stuck, is a section in the sketch where I need that something happens if a certain data arrives.
My project consist in one Arduino (sender) with two buttons (page 1 and page 2) in a tft shield… that send two commands (toPage1, toPage2) via serial to the others (receivers) that have the same sketch uploaded.
If I open the serial monitor of each receiver, they show that received data is accurate… but where I say “if receiving this…do that…” is not working.
I’ve tried the “if (receivedChars…” in all ways my limited knowledge could imagine ("", (), =, ==) compared with researched codes and also I tried to modify the functions at the bottom of the sketch with no results… time to ask for help
I attached the code due to size.
Thanks in advance
