/Subject (Offset calibration is very important for applications such as tilt for gaming and hand gesturing on mobile phones/PMP/PDA devices. There are a number of proponents when it comes to offset errors such as trim errors, mechanical stresses due to package and mounting, shifts due to temperature and aging.

AN3841, Performing Offset Calibration using the MMA7660FC
Freescale Semiconductor, Inc.
Offset calibration is very important for applications such as tilt for gaming and hand gesturing on mobile phones/PMP/PDA devices. There are a number of proponents when it comes to offset errors such as trim errors, mechanical stresses due to package and mounting, shifts due to temperature and aging. This application note will describe how to do offset calibration for the MMA7660FC with a Microcontroller.
