I tried many library for the MPU-9250 ,but can't find any which outputs orientation data using DMP. Iused an MPU 6050 with DMP from the examples here -
The data output was rock solid.
is there any similiar way to get DMP data from MPU-9250?
Starting with a Google search for MPU-9250 I found SparkFun 9DoF IMU Breakout - ICM-20948 (Qwiic) - SEN-15335 - SparkFun Electronics which points to
https://learn.sparkfun.com/tutorials/mpu-9250-hookup-guide and near the bottom of thst page is a part that says:
Many of the advanced features of the MPU-9250 are only accessable by agreeing to a pages of licensing terms and logging in as a developer to get access to Embedded MotionDriver 6.12. This approach isn't super Arduino friendly. At power up 3062 bytes of undocumented hex needs to be loaded into the MPU-9250.
