    ADC Measuring Wrong Value




      I am guessing this is something simple I am overlooking, but I am unable to get the ADC to correctly read input voltage values.  See the attached project.  For example, my multimeter (and a back up) are reading:


      ADC 0:  2.368V


      ADC 2:  2.283V


      The processor is computing:


      ADC 0:  2.255V


      ADC 2:  2.180V


      Both values are about 5% different - could be a red herring.


      Any ideas?


      Thank you,
