/*
   This sketch example demonstrates how the BMI160 accelerometer on the
   Intel(R) Curie(TM) module can be used as a Step Counter (pedometer)
*/

#include "CurieIMU.h"

/* To get an interrupt notification for every step detected,
    set stepEventsEnabeled to true. Otherwise, the main loop will
    poll for the current step count.

   By design, the step counter does not immediately update on every step detected.
   Please refer to Section 2.7 of the BMI160 IMU SensorData Sheet
   for more information on this feature.
