Gyroscope calibration example using SensorQMI8658.

This example demonstrates how to:

• Perform on-demand gyroscope calibration
• Read and save calibration gains
• Apply saved calibration gains
• Set accelerometer and gyroscope offsets

Note

Place the sensor flat and motionless during calibration. Calibration corrects for sensor bias and gain errors.
