Thanks Jim If I understand it correctly, say a chip has 1K RAM, the stack size could in theory range from 0 to 1K?

how to calibrate non-linear ADC reading?
the over sampling technique works pretty good, I am happy with that. And thanks all of your advice how to get a better ADC reading, I will implement those in my future projects....
