Pedometer (step counter) example using SensorQMI8658.

This example demonstrates how to:

• Configure pedometer parameters
• Enable and disable pedometer
• Read step count
• Reset step count

Note

The pedometer counts steps based on accelerometer patterns. Calibration may be needed for accurate step detection.
