How to adjust values to a new range
I have 10-bit ADC reading with a usable range of 400 - 930.
How can I adjust that value to create a range of 100 to 230?
I've been dividing the ADC by 4 to get a PWM of 0 to 255, but all PWM values below 100 are useless, and values above 235 will shorten the life of a LCD.
I'm at my wits end after 2 days.
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!
