Dear Community,

I am using the FXOS8700CQR1 sucessfully on Atmel controller.

But every second time, the calibration fails:

First time I can calibrate it.

xmag average= -474

ymag average=-569

zmag average=-626


when I start the second time, calibration fails with

xmag average= -82

ymag average=-88

zmag average=-374


I have reviewed and compared code with examples here:

FXOS8700CQ - Bare metal example project 

Accelerometer and magnetometer FXOS8700CQ example code for MQX4.1.1 


Problem I still cannot get it. The problem is reproducible every second time.


I call both calibration from the attached library.





thank you and best regads,
