实现基于 RV-8263-C8 和 PIC32MZ2048EFH100 的精准实时时间追踪

/*!
 * @file main.c
 * @brief RTC 15 Click example
 *
 * # Description
 * This example demonstrates the use of the RTC 15 Click board by initializing
 * the device and setting up the current time and date. It continuously
 * reads and displays the updated time and date every second using the timer
 * countdown interrupt pin.
 *
 * The demo application is composed of two sections:
 *
 * ## Application Init
 * Initializes the logger and the RTC 15 Click driver, applies the default configuration,
 * and sets the starting time and date.
 *
 * ## Application Task
 * Waits for a 1 Hz interrupt signal and then reads and displays the current time and date.
