Steve: I forgot to mention, I do have .1 uF caps across my +5V & GND inputs to the board, and across the PIC. Thanks for the suggestion! --John Steven Kosmerchock on 02/17/99 02:45:16 PM Please respond to pic microcontroller discussion list To: PICLIST@MITVMA.MIT.EDU cc: (bcc: John Esposito/gg/DadeInt) Subject: Re: Hardware or software problem??? John, I had similar problems when I first started using PICs. Try putting a .1 or .01 uF cap by the PIC. Put it at the PICs +5vDC to the PICs ground. Solved my problem! Hope this helps.
