使用INA381和STM32F302VC实现电流水平的实时监测

/*!
 * @file main.c
 * @brief Current5 Click example
 *
 * # Description
 * This example application showcases ability of the device
 * to read raw adc data and calculate the current from it.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of communication modules(SPI, UART) and 
 * additional pins for controlling device(RST, ALERT->INT).
 *
 * ## Application Task
 * Read ADC data with SPI communication and calculate input current.
