使用TPS389006和STM32G431RB以高精度监控多个电压水平

 * @brief HW Monitor 3 Click example
 *
 * # Description
 * This example demonstrates the use of HW Monitor 3 click board by reading and
 * displaying the voltage level from 6 analog input channels.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Reads the voltage level from all 6 analog input channels and displays
 * the results on the USB UART once per second approximately.
