I have two versions of the ADC128S102EVM board: a small one we bought a year ago and a much larger one where all the inputs are broken out to SMA connectors.
I can plug the old style ADC128S102EVM directly to an Arduino Due and it works fine.
But connecting the newer style board directly to the Arduino returns a zero value all the time. But the setup starts to magically work if the control lines go to a protoboard before going to the Arduino.
I'll double check the jumpers I'm using but I don't think that's the problem. We have a second "new style" board in a test configuration at another facility and it doesn't work when directly connected to the Arduino either.
Any other suggestions?
