LogStick Project #3

This project from Rod Crawford's LogStick Blog is the third of a series of examples that show how to get started using the RealView Microcontroller Development Kit for ARM devices.

This project (taking an external interrupt from a pin) doesn't exactly work. However, it is quite interesting to watch what doesn't happen so I have included it. If you run up the example code you will see that all is running very nicely until you "Push my Button"; then all hell ensues...interrupts just keep on happening (the counter in the pressed routine shown in Watch pane #1 bottom middle, just increments endlessly) and the main program doesn't get a chance to run (the blinking pin doesn't blink anymore).
