UM7 calibration

[VSI]

I noticed there are a lot of hidden registers related to calibration in the CHR Serial Interface.
Is there a (mathematical) description of what these registers do, or information on how to calibrate the UM7?

A basic overview of how we do calibration can be found here: http://www.chrobotics.com/library/sensors-for-estimation We don’t currently have an app note to describe methods of determining calibration coefficients.

Hi dear,
I found UM7 can trim Gyro zero shit value for x, y, and z components.
If UM7 have ability trim accelerate zero shit value for x, y, and z components.
If UM7 have ability trim Mag zero shit value for x, y, and z components.

Thanks.
