Method for setting initial compensation value in sensor complex module

摘要

A method for setting an initial compensation value of a sensor complex module, the method including the steps of: reading a preset sensitivity value and an offset; detecting an acceleration value; calculating an accelerating-force sensitivity value using the acceleration value and the offset value; calculating an accelerating-force error value using the accelerating-force sensitivity value and the sensitivity value; calculating a gradient error value using the accelerating-force error value and the acceleration of gravity; setting a polarity value according to the accelerating-force sensitivity value; and setting the accelerating-force error value, the gradient error value and the polarity as the initial compensation value.
