Ok....experiencing a few diffs here.

Basically I need IOC interupts (which I'm basing on a simpler cut down noobesque version of excellent Bruce's provided code)...but I also need timer interupts.

My problem is that I get a boat load of errors when my program compiles when IOC & timer interupts are enabled together - what are the errors I hear you say? Well, I'm at work right now so can't cut/paste in what I'm seeing, but what I can say is that when I remove the timer interupt it compiles fine. Or when I remove the IOC interupt it compiles fine - only when both are enabled does it spew out heaps of errors during compilation.

I also know that my overall code is fine - previously I was using the INT pin for interupts ...I was able to get both INT & Timer interupts enabled & working in that setup. So I'm figuring here that maybe this latest way of handling the switches - IOC interupts - are using up a whole lot more PIC resource than the previous way I was doing this? Maybe the combinbation of IOC interupts, timer interupts, plus my coat are pushing things too far?

How to progress this?
