Ok so I have Nigels tutorial 11.1 burned in the 16f88, and everything works well.
But, now if I let the project sit ON for more then 10 seconds, the lcd displays a bunch of garbage, and then almost immediately returns to its program.
This happens in a pattern . When I move my hand over the circuit, it goes hay wire.
Any idea if it has anything to do with no solder breadboard???
Maybe stray capacitance??
I have clean 5V power supply,and 10k on RA0 to stabilize it a bit, use Int_Rc, and thats it. other then pot for contrast. Using Optrex 16x1 display.
Should there be any capacitors also hooked up to RA0????
If so why???
Chip is running at 8 mhz. Still learning, as I also tried 4 mhz with same results.
Thanks.
