Drew Have you found that even leaving the input alone, there is enough 'noise' that if you do a compare of one reading to another, say seperated by a minute or so, that the LSB's are changing? I was looking at doing a comparison so if the input had changed, to reset and re-read the inputs, but I'd have to mask off the lower nibble else the noise was getting in the way of a real change. >From: Drew Vassallo >Reply-To: pic microcontroller discussion list >To: PICLIST@MITVMA.MIT.EDU >Subject: Re: [PIC]: A/D result trimming >Date: Mon, 1 Apr 2002 20:38:40 -0500 > >You're right, of course, Olin.
