Hi all, Thanks for all your feedback on XP. I might have to take the plunge! :-) I am just about to tackle the A/D convertor. Can anybody give me an idea of how many times you should check the A/D for a single reading? Is simply taking one reading good enough or is it preferred to take multiple readings and average them. What is considered "enough" samples for a single reading? Cheers, Sean -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
