Hi,
We are using ICM20948 and want to get the game rotation vector. When I put the sensor on a table, we get the game rotation vector value (0.940, 0.003, -0.130, -0.317). Sorry that I am not familiar with game rotation, is the game rotation values near to 0 if there is no rotation or movement? Could you tell me how the DMP in ICM20948 calculate the game rotation vector from acceleration and gyroscope?
Thank you
Hang
Hello,
Please refer to the document named "eMD_Software_Guide_ICM20948" inside the eMD driver package for the ICM-20948 to understand better about the game rotation vector algorithm. You can download the driver from: https://invensense.tdk.com/developers/software-downloads/
