Heheh yeah that looks really weird :) I guess I was too chicken to mess with the calibration for the battery ADCs earlier so I tried to keep it as it was in the Motorola driver. But now things are working and I can compare the results so it should not be a problem. > can't this code duplication be avoided?

Thanks yes. It was Kelvins in the Motorola driver. Will fix up the rest of your comments and repost. Thanks for looking and thanks for the good comments.
