ARM Core/Oki ML67Q5003

I’m new to developing code for embedded systems and I’ve been having some problems. I already have a demo program that uses a seven segment LED to count up in hex. For practice I’m trying to modify it so if I press a switch hooked up to an interrupt it changes from counting in hex to decimal.

My problem is with the interrupt, I think?

I don’t actually have an Oki ML67Q5003 board myself, I’ve using the one at TechOnLine http://www.techonline.com/community/ed_ … /virtualab. They put a development board online so you can write and execute code on it for free. This site is where I got the demo code also.

Any help would be appreciated.

Thanks,
