 * @file main.c
 * @brief Angle7 Click example
 *
 * # Description
 * This example demonstrates the use of Angle 7 click board by reading and displaying
 * the magnet's angular position in degrees and analog voltage output as well as
 * the magnet's status and magnitude.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Reads the magnet's angular position in degrees and analog voltage output 
 * as well as the magnet's status and magnitude and displays the results on the USB UART
 * approximately every 100ms.
