Does it take any significant time to change analogRead resolution? I need to measure which points are pressed in a pressure sensor matrix, first scanning fast with a low, faster resolution, then reading again the detected points with a higher resolution. I need the lowest latency possible.
Does the change in resolution take some time? Would it be more sensible to use different pins for low and high resolution readings?
