Release Notes for the MotionAC Accelerometer Calibration Library

# Release Notes for MotionAC Accelerometer Calibration Library

Copyright 2020 STMicroelectronics

What is MotionAC?

- The MotionAC provides real-time accelerometer calibration.
- The library acquires data from the accelerometer and counts the offset and scale factor coefficients together with the calibration quality value. The offset and scale factor coefficients are then used to compensate raw data coming from accelerometer.
