Using VREF pins for pots that don't reach ADC=0 or 255
If my pots don't go quite down to 0V or up to 5V, can I just use the VREF pins and tweak what the ADC uses as lower and upper limits with 2 voltage dividers?
(sorry, never done this stuff before)
It seems to me that trying to fudge the ADC values in software is not the best approach; especially if it can be fixed with 4 resistors.
My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.
Not as dumb as yesterday, but stupider than tomorrow!
