I'm curious to know if anyone has had any success correctly measuring battery voltage with the Artemis Processor with any of the MicroMod carrier boards.
The Artemis has its own 100 kΩ/150 kΩ voltage divider that is loading the 20 kΩ/10 kΩ voltage divider on the carrier boards, which requires some fun circuit math. However, the high resistance values may be causing problems with the Artemis' ADC.
I've opened an issue on GitHub here:
