To use the Analog to Digital Converter you use the ADCIN command. That command and all the others are decribed in the manual you shouldn've received when you bought PBP. If you have PBP3 then the manual even got installed as a.pdf on your system when you installed the compiler. If you have MicroCodeStudio a lot of information is available in the Help, the datasheet for your PIC is available from Microchips website and I'm sure that if you search the forum you'll find a LOT of info and examples showing how to use the ADC.

i have read the ADCIN command but i i do no how to link this command with the comparator, my aim is to design dc dc conveter with constant current by varying output voltage after comparison, So it's better for u HenrikOlsson to help me by giving sample code on that issue
