使用ACHS-7194和STM32L073RZ实现电流波动的持续洞察

/*!
 * @file main.c
 * @brief HallCurrent10 Click example
 *
 * # Description
 * This library contains API for Hall Current 10 Click driver.
 * The demo application reads ADC value, ADC voltage and current value.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes I2C driver and log UART.
 * After driver initialization the app set default settings.
 *
 * ## Application Task
 * This is an example that demonstrates the use of the Hall Current 10 Click board™.
 * In this example, we read and display the ADC values and current ( mA ) data.
 * Results are being sent to the Usart Terminal where you can track their changes.
