I'm using a KS0108 128x64 glcd from adafruit with my arduino mega. I wired everything up according to "pinout B" on the wiki. The glcd works wonderfully. So do sensors placed on analog inputs 0-7.
However, analog inputs 8-15 don't seem to work. I get crazy values (like when the ADC is connected to a floating pin). Is this normal? Does the glcd library render some (unconnected) pins on the arduino mega unusable?
Thanks in advance! -JFM
