I recently needed to do some work with Pin Change Interrupts and it was a bit of a learning experience for me. As it turns out, they’re actually pretty easy. I’m posting this so that when I need to look it up in the future, I can easily find it and maybe I can help somebody...
From Arduino 101: Timers and Interrupts1. Timer0:Timer0 is a 8-bit timer.In the Arduino world, Timer0 is been used for the timer functions, like delay(), millis() and micros(). If you change Timer0 registers, this may influence the Arduino timer function. So you should know what ...
Why Use Timers to Generate Interrupts? Often you want an action to be repeated at specific intervals. Timing your loops and adding delay statements to time your loops is difficult, may change and will not port to a faster processor (and there are faster versions of the ESP8266 coming out)....
