I have ZSTAR3. I want to calculate relative accelerations.
This means, when sensor stay on the desk I want to have using mathematical formula 0g in X,Y,Z-axis. When I moving I also want to calculate relative acceleration in X, Y, Z-axis.
For example. I have my sensor on hand and I begin move to up and down and I want to know with which relative accelerations in Z-axis I move this sensor.
Freescale programs give me only absolute acceleration in X, Y, Z-axis and absolute g.
My data from program of Freescale is in attachment.
