I have an application running on the MPU9250, using the inv_mpu and inv_mpu_dmp_motion_driver files to interface the sensor with my application. We wish to port our code to the ICM 20948, but I have not found similar files as the inv_mpu to make our migration easier. Is there any file similar to what the inv_mpu file is doing? We are using a dsPic33e development board to interface with the ICM20948
