This is an Arduino library that enables you attach an interrupt to any pin of Arduino Uno, Nano, Mini and other 328-based boards. The Arduino attachInterrupt() function only allows pines 2 & ~3.

I'm using a PWM output, and setup a pin interrupt so i can detect the start of the PWM signal. This works fine in 2.0.1, but not on 2.0.2 attachInterrupt should be able to attach to the output signal ...
