经过一段时间的使用，上次的硬盘MP3播放器增加了USB下载文件功能； 汉字LCD显示功能；子文件夹功能等。并对软件做了一些修改。并将 硬件电路图画出来了。由于做得仓促，难免有不妥之处，请大家谅解， 欢迎指出错误。谢谢。-After a period of use, the last of the hard disk MP3 player, an increase of USB download files function characters LCD display Subfolders functions. And the software to do some modifications. Hardware circuit and the pictures came out. As a result of doing a rush, inevitably something wrong with the U.S. understanding, please welcome to point out the error.谢谢.
