    Charles,

    This sensor pulses hi to low. I suspect some of my sampling is reading on the low part of the cycle. Thats why I slowed way down the sampling time to 20ms.

    ADC has worked well for me on this PIC.

    I will look at your subr.

    Thanks
    James

    An analog sensor that pulses high to low? I don't understand. What sensor are you using.

    Default changing to PULSIN

    I am getting better results using PULSIN since the sensor is pulsing as stated before.
    I still need to condition the results, however.

    You mean that you weren't concerned with the analog level of the signal at all? Only its duration?
