使用ADA4570和PIC18F57Q43测量旋转轴的角度

 * @brief AMR Angle 2 Click example
 *
 * # Description
 * This example demonstrates the use of AMR Angle 2 Click board by reading and displaying
 * the magnet's angular position in Degrees and a system temperature in Celsius.
 *
 * 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 a system temperature in Celsius 
 * and displays the results on the USB UART approximately every 100ms.
