I have been working with this Super Pro board for some time, now all I get are Zero readings from AD2, AD4, and AD5. I am using AD3 as a DAC output. I don't know if that is working at this moment. These were all working in the past. I haven't changed any setup code.
I did have a problem with a high voltage on the 3.3 Volt pin.
Did I damage the Super Pro board? The code runs except where the Zero readings cause operations to fail.
