How to get Euler's angle Yaw,Pitch and Roll in lsm6dsv16bx

[Varsha]

Is there any function I can use to calculate the yaw and pitch directly from the IMU? Or do I need to find the quaternion(SFLP) and then calculate Euler's angle on my own?

Hi @Varsha ,

I think you are looking for the sensor fusion library to get quaternions and Euler angles.

You can refer to the MotionFX library of the X-CUBE-MEMS1 firmware function pack, which runs as middleware on STM32 and provides real-time motion-sensor data fusion. It also performs gyroscope bias and magnetometer hard iron calibration.

After getting the quaternion values, How do i convert the quaternions to euler angles? can you please share some code/ documentation / link for the same.

I'd imagine examples are a search away..
