can you use two arduino boards with one nextion display?
if so, how? i've tried to do it but once i get it all hooked up, it does not work correctly
RS232 interface is a Master-Slave concept per design. One Master talks to one Slave ...
You can add multi Clients to the line, but there can only be one sending Master at the time.
i was looking for one board to run a program completely separate from the other. i have a temperature program with heat and a/c control, but no matter what i do, i can't seem to run this on the same board as all my other listen for functions that i'm running as the temp control is too busy.
i tried putting in millis(), but then everything else stops working.
