For whatever reason my analog inputs are all reading arbitrary values (i.e. 0.40xxxxx v to 0.83xxxx v ) on any given analog input, AIN 0-6 with little or no change. I am running Debian Wheezy with the Adafruit IO library, and everything else seems to work fine such as the PWM. If I input a voltage such as 1V I see a slight change in the readings, but it is very small. When I interrogate the inputs without anything connected I get these phantom voltage readings. I have never exceeded the 1.8V max on the analog inputs and have always left a little head room on the input voltage to be safe. I had been using the analog inputs without issue till recent, now I am stuck. Not sure what to try or look for, any suggestions would help me greatly.
