hello I have an ArmmitePro , using C compiler.
I'm having some problems with the ADC, data returned by AD() changes in time
(even of the value in the ADC pin is stable. I connected the sensors ground with
ADC groud, but still !!
is it the board or I have a config problem,
thank you

Re: AD values
I'd expect to see +/- 64 as the 10 bits are left justified into a 16 bit field.
That would correspond to a change in the LSB.
My testing was done with a battery connected to analog GND and one of the AD
inputs, and it yielded data good to 10bits.
What else is on the 3.3V ?
What are your trying to measure and what powers that circuit?
