Interrupts – Steep Learning Curve

Well have the controller setup and have uploaded the demo code, all working 🙂  Now down too some serious work in getting connected to the board. 

The Board is based on the AT91SAM7X MPU, of which I have absolutely no experience, so the learning curve begins (right at the bottom).  First thing I want to do is get the interrupts for the two wheel encoders working.  From my initial research I gather that any of the inputs on the GPIO can generate an interrupt on a state change, exactly what I want.  So now more research on how to make it happen using the 7 GCC tools I’ve installed, all demo code is compiling and working ok.

Looks like my starting point is some examples found here http://gandalf.arubi.uni-kl.de/avr_projects/arm_projects/index_at91.html
