This goes back to my original question over a year ago
Rather than open back up the old post since it is a bit dated I thought I would ask about the status.
Has this ever been addressed in the SDK as indicated? I am using the 4.2 R3 release on my EMX development board, and still have the exact same issue. The analog values are just all over the place. However, the same code works perfect on my Netduino.
I have even tried (as suggested) putting all my unused analog pins to ground, and that does not work. Is the EMX board (and the Cobra v1) just not good for analog reading? I just ordered 2 Cobra II WiFi boards, so am a bit concerned that this may still be an issue.
I have read that perhaps it is because the 3.3v on the board is not a true reference voltage and can bounce around a bit. Is that true?
