A Again I say use the cap to drive an osc, divide freq via hardware (counter chip) or via PIC prescaler etc and test freq against the PIC clock. All system capacitances are negated provided you can calibrate the system degrees/freq which will have to be done anyway. :o) -Roman -- http://www.piclist.com#nomail Going offline?
