    Paul & other

    I have increased the sample time to 200 using DEFINE ADC_SAMPLEUS 200 but it did not solve my problem.
    I have also tried Fosc/32 by setting DEFINE ADC_CLOCK 2, but no luck!

    In my program I am using mister_e's matrix keypad routines and Watchdog is disabled.
    I am also running HPWM in the background which is pulsing the current I am trying to measure. The HPWM is switched on/off at defined intervals.
    Can this influence the ADC readings?

    Next I will try a cap on RA3......
