Resolved! Using STM32F446, ISM330DHCX and MotionFX, computed yaw angle is correct after a controlled 90-degree right rotation, but the yaw angle is off by ~3 degrees after each 90-degree left rotation. What could be causing this issue?

The MotionFX Library is initialized as follows: MotionFX_getKnobs(&iKnobs); /* Modify knobs settings */ // Configure knobs with non-default values iKnobs.output_type = MFX_ENGINE_OUTPUT_ENU; iKnobs.modx  = 1; // No decimation iKnobs.ATime = 10; // ka...
