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...

Porting arduino libraries to libmraa as UPM libraries is usually fairly easy. The issues typically come from misunderstanding of how a non real time OS deals with interrupts and timers. It also highly depends on the sensor. A concrete example is explained in detail onMaking a UPM module for ...
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 ...

The timers are interesting, though, they may require some changes to work with 1284p. You MAY be the first person to use them on this chip. If you run into trouble, post to the Arduino forums. There are a handful of people using 1284p now, and one of them may have used the timer...
The ATMega328 has 3 timers that can used in various ways including keeping time, triggering interrupts, PWM etc. Arduino uses upTIMER0for functions such asmillis,microsetc. TIMER1andTIMER2are available. Below is a contrived example of building a custom timer based on TIMER2. The code is des...
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)...
