Thanks to everyones for there help. One thing for sure I am certainly learning alot.
Good game... Any idea what the real problem was? Miswired? One wire off?
Keep in mind, the PBP manual, while not a 'do-all end-all of manuals', has a lot of good information in it, a lot of it 'in between the lines', and a lot of it applies to this PIC and that PIC since they're all pretty much built on the same architecture. Use it and use it often! It'll save you a lot of time and trouble. Same goes for the PIC datasheets. A load of the problems that show up here could have been avoided by those two items.
