使用ALS31300和STM32L073RZ体验磁场检测的未来

 * @file main.c
 * @brief 3DHall9 Click example
 *
 * # Description
 * This example demonstrates the use of 3D Hall 9 Click board by reading the magnetic
 * flux density from 3 axes as well as the angles between axes and the sensor temperature.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and the Click board.
 *
 * ## Application Task
 * Reads the new data from the sensor approximately every 300ms and displays 
 * the measurement values on the USB UART.
