    fratello. Yes I saw that one but it isn't this one, this one had various calibration routines etc in the code. Notice the defines for xtal osc. I do remember the author for mine came from India.

    Hank,
    I'm getting old I just don't get this. I've modded the board to have the .47 (not.047 as i put above) in series to the ground line and put a 100k to the adc input as per the schematic from the link above. This uses a 16f876 and I've duplicated the adc input circuit. They are claiming up to 10amp and with 10mA resolution.
