how to use the MPU-9250 integrated DMP instead of the raw data from the gyro & accelero ? #106

Hi everyone,

I'm struggling to get smooth data from the motion sensors even after filtering the raw data with an A.H.R.S.

Any ideas on how to calibrate the magnetometer ?

Perhaps you could implement a "calibrate" function.

Thanks in advance,

The only info i can find is hear: http://processors.wiki.ti.com/index.php/CC2650_SensorTag_User's_Guide#Calibration

Maybe TI's iOS or Android apps can calibrate the sensors?

Perhaps you could implement a "calibrate" function.

Pull requests welcome for this.

Hi thanks for your quick answer.

I've done some reading of the MPU-9250 specification and there seems to be a integrated component (DMP) to compute all three sensors data into valuable data (quaternion, pedometer, orientation etc...).

Arduino implementation exists here.
