 * \brief Mpu9Dof Click example
 * 
 * # Description
 * MPU 9DOF Click carries the world’s first 9-axis Motion Tracking device. It comprises two chips: one that contains 
 * a 3-axis accelerometer, a 3-axis gyroscope, and a DMP (digital motion processor); 
 * the other is a 3-axis digital compass.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enable's - I2C, initialize MPU-9150 XL G & MPU-9150 MAG and start write log.
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of MPU 9DOF Click board.
 * Measured accel, gyro and magnetometar coordinates values ( X, Y, Z )
 * and temperature value in degrees celsius [ �C ] are being sent to the uart where you can track their changes.
 * All data logs on usb uart for aproximetly every 1 sec.
