I think I am missing a step. Trying to read a voltage on Analog0 and measured with a meter its 1.77v but when I read in program I get .5079 (float from .Read()) or 2074 from .ReadRaw(). Is there a calibration setting I am missing? I read about having to pull up the AREF but thought on the Plus 2's that is not necessary. Thanks for any pointers.
(wont be reading anything beyond 3.3v, had a voltage dividing in the circuit but don't really need it)
