Use your LEDs

• Indicate phases of program operation by illuminating LEDs. In particular a lot of electrical faults cause the PIC to resst. The first thing your code should do is illuminate a "startup LED" for 100mS. If you see that flashing repeatedly, you'll know your PIC is reseting.

Runs with ICD unit attached, only

• Make sure you are not in debugger mode. Try adding the NOBROWNOUT fuse at the top of your code.
