 * @brief 3D Hall 14 Click example
 *
 * # Description
 * This example demonstrates the use of 3D Hall 14 click board by reading
 * the magnetic field strength from 3 axes and the sensor internal temperature.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Reads data from the sensor and displays them on the USB UART every 200ms.
