使用AEAT-9922和PIC18F57Q43确保磁体旋转全范围内的精确测量

 * @brief MagneticRotary2 Click example
 *
 * # Description
 * This example demonstrates the use of Magnetic Rotary 2 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 performs the click default configuration.
 *
 * ## Application Task
 * Reads the magnet's angular position in degrees every 100ms and displays the results on the USB UART.
