1. The analog input cannot measure and shouldn't be exposed to higher than 3.3V. 2. If you're using a resistor divider as recommended, I recommend a 1uF or greater ceramic capacitor in parallel to the low side resistor. Otherwise, use smaller resistors (like, a couple of kOhm), but that will come at the cost of wasting some power. On May 12, 2015 11:42 AM, "tdg a" <[email protected]> wrote:
