 * \brief Accel5 Click example
 * 
 * # Description
 * This application allows linear motion and gravitational force measurements.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes Driver init and settings accelerometer data range and mode.
 * 
 * ## Application Task  
 * Reads the accel X / Y / Z axis data, every 500 ms.
