这家伙很懒，什么也没写！

参数主要是地址和写入读取的个数，
/**
 * This function write the specific numbers of data to the specific position
 *
 * @param bus the name of at24cxx device
 * @param WriteAddr the start position to write
 * @param pBuffer  the data need to write
 * @param NumToWrite
 * @return RT_EOK  write ok.at24cxx_device_t dev
 */
rt_err_t at24cxx_write(at24cxx_device_t dev, uint32_t WriteAddr, uint8_t *pBuffer, uint16_t NumToWrite)

/**
 * This function read the specific numbers of data to the specific position
 *
 * @param bus the name of at24cxx device
 * @param ReadAddr the start position to read
 * @param pBuffer  the read data store position
 * @param NumToRead 
 * @return RT_EOK  write ok.
 */
rt_err_t at24cxx_page_read(at24cxx_device_t dev, uint32_t ReadAddr, uint8_t *pBuffer, uint16_t NumToRead)

/**
 * This function read the specific numbers of data to the specific position
 *
 * @param bus the name of at24cxx device
 * @param ReadAddr the start position to read
 * @param pBuffer  the read data store position
 * @param NumToRead
 * @return RT_EOK  write ok.
