Hello, PICLIST members: I need some advise on using the A/D Convertors on my PIC 16c73's. Specifically: HARDWARE implementation. (Ex: 1M Ohm series resistors to the input pin???) I seem to get erratic readings if one of the inputs is left "floating", and not actually reading a voltage. Thank you in advance, 6500 7000 Dave Celsnak ___7500 / / 8000 (Shift!) /-/ / / RPM / / / /
