使用ISL1221和STM32F410RB让每一刻都变得重要

/*!
 * @file main.c
 * @brief RTC14 Click example
 *
 * # Description
 * This is an example that demonstrates the use of the RTC 14 click board™.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of I2C module, log UART and additional pins.
 * After driver initialization and default settings,
 * the app set the time to 11:59:50 PM ( 12-hour format ) 
 * and set date to Thursday 05.08.2021.
 *
 * ## Application Task
 * This is an example that shows the use of a RTC 14 click board™.
 * In this example, we read and display the current time ( AM or PM ) 
 * and date ( day of the week ), which we also previously set.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs write on USB changes every 1 sec.
 *
 * ## Additional Function
 * - static void display_day_of_week ( void ) - The function displays the day of the week.
