USING DMP 9 axis DOF，angle cannot stop immediately #118

Closed muniye closed 1 year ago

muniye commented 1 year ago

I used icm20948 DMP 9 AXIS DOF to output attitude Angle datas. The magnetometer was calibrated well through 8-figure calibration, and the data response was good. However, when the sensor stops after motion, the Angle does not stop immediately, and the Angle data still takes 0.5 to 3 seconds to stop. (It seems like calibrating).The more intense the exercise, the more obvious the phenomenon.I did not have this problem when I used icm20948 DMP 6 AXIS DOF. Because I use icm20948 as a mouse, this problem is unbearable.

Hello @muniye ,

I am sorry. I do not have an answer for you. There are many things about the DMP that we do not understand. If you look through the open and closed issues, you will find long discussions about the behaviour and performance of the DMP.

Very best wishes, Paul
