However, doesn't the 14000 have a 12 or 14 bit ADC(I can't remember)? PICs are good for measuring circuits (voltmeters, scales, colorimeters, etc.) and these all need the extra precision. (Microchip should indeed take a hint) Sean +--------------------------------+ | Sean Breheny | | Amateur Radio Callsign: KA3YXM | | Electrical Engineering Student | +--------------------------------+ Save lives, please look at http://www.all.org Personal page: http://www.people.cornell.edu/pages/shb7 mailto:shb7@cornell.edu Phone(USA): (607) 253-0315
