If I went the interrupt route, would I basically move the entire contents of my main loop into an interrupt routine and update the display in my main loop? Is it really as easy as that?
Yes, exactly. Problem is, you need to look for a suitable Arduino Library. Oliver
I will definitely look into it! Could you elaborate on why a library is needed?
If I remember correctly, the Arduino IDE does not provide timer based interrupts. So for the creation of repeated/perodic tasks you need a library.Oliver
