I'm sure it's a simple thing, but what could the reason be for my microcontroller (PIC18F2550) randomly turning on and off? It seems to happen every time i touch one of the rails which makes me think its something to do with the supply voltage...? I'm using an ATX power supply from a computer with LM317 voltage regulator.
Is there not an "enable" pin that I'm missing out?
Floating input pins alone for normal inputs will NOT cause resets. Not unless there's a piece of code which will do something funky and cause a reset when there's a 1 or 0 on one of those pins.
Low Voltage Programming enabled and leaving the LVP pins floating will. Had that prob...
