Having struggled unsuccesfully to get a simple pendulum driver program working I have gone back to basics in order to check out my programming. i have built a basi cbreadboard with a 16f628A It simply has the supply connected (5V) and the 5 lines necessary from a pickit 2. There is an LED with 1K in series hanging on port b.3. Sometime it works sometime it doesn't.
Bringing a finger to within an inch of the pickit2 makes it run. Have I gone mad (again) or have I just done something unspeakably daft ?
