I have configured the ADC on the PIC16F870.
I am not sure what kind of signal or DC level should be in it without any connection at this pin.
I put the oscilloscope and I see this signal at RA0/AN0 pin
does it is correct?
even with a signal the same pulsed signal is mounted over the DC level
does I need a capacitor or what configuration is needed?
thanks
