I have a strange anomaly with the ADC on a MEga32.
The ref voltage is 2.5, input voltage to channel 2
is 1.25. ADC reading settles at 511 or so. After
sitting with no activity for several hours, the ADC
reading drops to 508 or so but the input voltage
and ref voltages are stable at their proper values.
Any ideas?
Doug
