 * @file main.c
 * @brief Magneto 14 Click example
 *
 * # Description
 * This library contains API for the Magneto 14 Click driver.
 * The demo application reads and displays 
 * the magnet's angular position in degrees.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of SPI module and log UART.
 * After driver initialization, the app executes a default configuration.
 *
 * ## Application Task
 * This example demonstrates the use of the Magneto 14 Click board™.
 * Reads and displays the magnet's angular position in degrees.
 * Results are being sent to the UART Terminal, where you can track their changes.
