Analog Read gives wrong value.posted in Atom
I am running a sketch on an ATOM Lite using GPIO 33 as an analog read pin. When connected to 3.3V (which actually measures 3.18V) it gives 4095 as expected. If connected to GND it gives 0 as expected. However if the voltage on GPIO33 is 3.11V it still shows 4095.
By my maths at 3.11V it should show 4004.
Any help appreciated.
