I find problem in selecting more than one ADC inputs to the pic 16f877 controller. in the program(C language) if one ADC input is zero the next subsequent ADC input scanned does not reach the full count 1024 (ie 10 bit ADC ) instead it reaches only 660 counts when the analog input is 4.95V which is equal to VPP(note-vref is internal & 8analog i/p selected ).If there is any solution, please let me know.
