使用 TMAG3001 和 STM32F302VC 实现 3D 磁场感应与角度位置测量

 * @file main.c
 * @brief 3D Hall 13 Click example
 *
 * # Description
 * This example demonstrates the use of 3D Hall 13 Click board by reading the magnetic
 * flux density from 3 axes, and the angle and magnitude between X and Y axes  
 * as well as the sensor internal temperature.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Reads data from the sensor approximately every 100ms and displays the measurement
 * values on the USB UART.
