Potentiometer Jitter; Does anyone know how to prevent this?
I am ADC sampling the voltage from a simple potential divider formed using a potentiometer. My code will only update the stored value if the value has changed by 1 (5v/256)= 19.5mV (for 8 bit). Occasionally I get oscillations between two values... obvious why really.
I notice that a lot of professional systems using this technique don't suffer from jitter, does anyone know how this is corrected? I still need to detect a change of one l.s.b in 8 bits.
