Hello,

I'm trying to read an analogue signal using the internal ADC, but it seems to have problems readding small signals. My analogue signal goes from 0 to 3V, in increments of about 1mV, but when reading the signal I get a range of readings, and it doesnt seem to settle. I'm reading every 100msecs this signal.

p.e. when the signal is locked at, lets say, 10mV I get an oscillatory reading that ranges from 6 to 10mv.

Has anyone dealt with this problem? any clever solution?

thanks in advance!
