使用24AA025E64和STM32F031K6为您的应用提供唯一的节点地址

/*!
 * \file 
 * \brief MacAddress Click example
 * 
 * # Description
 * Provides a unique node address for your application.
 *
 * The application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enables - I2C, also write log.
 * 
 * ## Application Task - (code snippet) This is an example which demonstrates the use of MAC Address click board.
 * MAC Address click communicates with register via I2C protocol by the write to register and read from the register.
 * This example shows write/read single byte and sequential write/read from EEPROM.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs write on USB uart changes for every 1 sec.
