 * @file main.c
 * @brief 6DOF IMU 28 Click example
 *
 * # Description
 * This example demonstrates the use of 6DOF IMU 28 Click board by reading and displaying 
 * the accelerometer and gyroscope data (X, Y, and Z axis) as well as a temperature measurement
 * in degrees Celsius.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Waits for a data ready indication and then reads the accelerometer, gyroscope, and temperature
 * measurements. The results are displayed on the USB UART at 7.5 Hz output data rate.
