使用 TMAG5170 和 TM4C1294KCPDT 测量三轴磁通密度

/*!
 * @file main.c
 * @brief 3DHall10 Click example
 *
 * # Description
 * This example demonstrates the use of 3D Hall 10 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
 * Waits for the conversion complete interrupt and then reads the new data from the sensor 
 * approximately every 100ms and displays the measurement values on the USB UART.
