Ok I've spent most of the day on this and I'm still struggling so am going to ask here.
I want to use an interrupt to take information from a digital pin on the Ardupilot.
My questions are:
What interrupts are used by Ardupilot, or, more importantly, what ones aren't and are free for me to use without messing up the existing code?
-and-
What digital pin is best to use?
I've looked on Arduino.cc and in iom328p.h; external interrupts exist for digital pins 2 and 3, but I can only see digital pins 6-8 and 11-13 on Ardupilot, is this correct?
It looks like I can change the pin of an interrupt but I'm not quite sure how to do so.
Any information would be greatly appreciated.
All the best,
Nick

What is Ardupilot using digital pins 2 and 3 for?
Has it used up all the interrupts or can I re-assign one?
Thanks.
