 * @brief 6DOF IMU 16 Click example
 *
 * # Description
 * This example demonstrates the use of 6DOF IMU 16 click board by reading and displaying 
 * the accelerometer and gyroscope data (X, Y, and Z axis).
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver performs the click default configuration, 
 * and checks communication by reading device ID.
 *
 * ## Application Task
 * Reading the accelerometer and gyroscope measurements, results are displayed on the USB UART every second.
