oh, also, the accelerometer values, I forget what units they are in, but they are not in G by default. I don't recall what it was, but I had to convert it by dividing by 28xx(don't remember what "xx" values are). My conversion and code are at home, I will look for it later. If you don't need an EXACT value now, just let the sensor sit still and take an average value of the Z axis (make sure the sensor is as flat as possible). This value should be about equal to 1G of accleration, so use that number to divide all of your accelerometer values before printing them to the serial port and they will be in G's.
