16F628A - Stops if release power switch.

Alain,

Weird you would say that - see attached...;o}

dene12,

See the attached example for one way. Note this doesn't help for your power button. The PIC needs power to operate, so just power it all the time, and give the attached example a whirl. Place a pull-up resistor on /MCLR. When you press your button it should ground the /MCLR pin.

Note: You'll get faster responses for assembly code on the Microchip forum. If you need to tweak the example attached, visit http://forum.microchip.com/

We normally stick to PBP BASIC around here...;o}
