 * \brief Accel8 Click example
 * 
 * # Description
 * This application measures accelermeter and gyroscopic data and temperature.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver init, reset chip and start configuration chip for measurement.
 * 
 * ## Application Task  
 * Reads Accel X/Y/Z axis, Gyro X/Y/Z axis and device Temperature. 
 * All data logs on the USBUART every 2 sec.
