使用N24C32和STM32F446RE体验超越限制的数据存储

/*!
 * @file main.c
 * @brief EEPROM 10 Click example
 *
 * # Description
 * This example demonstrates the use of EEPROM 10 click board by writing specified data to
 * the memory and reading it back.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and USB UART logging.
 *
 * ## Application Task
 * In this example, we write and then read data from EEPROM memory.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs write on USB UART changes approximately every second.
