Example of using FXAS21002 Gyroscope in FRDM-K66F? Calibration required?

Hi, Im new here.

 

I just got a FRDM-K66F development board and would like to record angular velocity from its FXAS21002
 gyroscope. I've already tried the examples/demos from the SDK which use the accelerometer (e.g. frdmk66f_bubble). Is there a similar example for the gyroscope?

 

In addition I'm curious if those sensors are calibrated or what type of calibration has to be performed. Is it enough to remove an offset (bias), or is there also a gain (scale) error, that needs to be removed?

 

Thanks for any pointers.
