I have a simple question: When using the DMP on the SEN-14001 using the MPU9250_DMP_Quaternion example code it appears that the magnetometer is NOT used to compensate for gyroscopic drift. It drifts about 1 degree every 3.5-4 minutes.
I am well aware of how gyros drift and how to compensate for them. It's just that I thought the DMP performed the compensation with the magnetometer but it appears it doesn't. Can someone just confirm this for me?
I am used to using the old 9DOF razor from Sparkfun and the firmware always appeared to compensate for drift with the magnetometer. I could run it for hours and my yaw never drifted.
