使用ACS70331和STM32F446RE实时洞察电流行为

/*!
 * @file main.c
 * @brief Current 4 Click Example.
 *
 * # Description
 * This example showcases the ability of the Current 4 Click board.
 * It configures Host MCU for communication and reads the voltage 
 * of AN pin and calculates current on load output.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of the communication modules(ADC and UART).
 *
 * ## Application Task
 * In span on 500ms reads voltage and calculates the current on load.
