Adding more interrupts


I'm quickly running out of interrupts, well infact - have run out of interrupts in a project I'm working on. Looking on the Atmega328P page, it says there are 24 external interrupts available. Same sort of thing goes for the 1284P that I'm using...

Can I simply modify a file somewhere to allow me to utilise more of these interrupts within the IDE?

You need the pinchangeint library, here is a bit about it including where to find it and an example use -
