通过四个CRR05-1A和STM32F446RE实现卓越的负载控制和监测

/*!
 * @file main.c
 * @brief Relay 7 Click example
 *
 * # Description
 * This example demonstrates the use of the Relay 7 click board by toggling the relay state.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of I2C module and log UART.
 * After driver initialization, the app executes a default configuration.
 *
 * ## Application Task
 * The demo application toggles the state of all relays every 5 seconds. 
 * The results are sent to the UART terminal, where you can monitor their changes.
