I'm having an issue with the Michrochip 3208 ADC.
I'm using the example code from the playground and it seems pretty straight forwardhttp://arduino.cc/playground/Code/MCP3208
Right now all I gout out from the serial monitor is
I'd expect 4095
I've tried connecting +5V to the Channel 1 and 2 inputs but there's no effect. Has anyone had similar issues? Is there a better way to test whether the chip is working as intended?
Eventually I'd like to use pseudo-differential input but for now i'm sticking to the single ended setup used in the example until I figure out what's wrong.
