Im currently putting some sensors on my zigbee-board but the a/d converter stops at 01 FFat Vcc/2 all higer voltages dont change anything anymore. beyond that it works well (with a 2k-potentiometer between Vcc and Gnd) I'm really helpless what the problem is... PIC 18LF4620 @ 3.2V

Dear Sebastian, your description of the problem is very rudimentary but I think it looks like that you are measuring in differential mode. In this case you can detect voltages from -Vref to Vref instead of measuring from 0 to Vref. So you are loosing one bit on resolution. Greetings from Germany
