使用A31315和STM32G431RB实现非接触和精确的磁铁位置跟踪能力

 * @file main.c
 * @brief Magneto 12 Click Example.
 *
 * # Description
 * This example demonstrates the use of Magneto 12 click board by reading and displaying
 * the magnet's angular position in degrees.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Reads the magnet's angular position in degrees every 100ms and displays the results on the USB UART.
