i think the range is from -2g to 2g m/s2.
so if the data is 32768,and the output is 2g m/s2.
It is depending on the physical sensor setting.
If you set the sensor to 2G range, then the lib output full range is +-2G.
If you set the sensor to 4G range, then the lib putput full range is +-4G.
BSX lite is just calculation the sensor data
