使用AS5510和PIC18F47Q10测量磁铁的线性和旋转运动

 * @brief Magneto11 Click example
 *
 * # Description
 * This example demonstrates the use of Magneto 11 Click board by reading and displaying
 * the magnetic field strength value.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Reads the magnetic field strength value in milliTesla and displays the results on the USB UART
 * every 200ms approximately.
