Aaah.. ofcourse, stupid me, if I had stopped looking for answears in the manual and instead been thinking of how a DA-converter works this would have been obvious.

Still, how do I handle decimals ? ..if I just want to display the voltage on the LCD to begin with ? ..and then cobnvert it to a real value with the formula ?
