上述程序可以通过编译，上传时间有点长，出错信息如下：
C:\Program Files (x86)\Arduino\libraries\EPD\src/EPD.h:1:18: warning: extra tokens at end of #ifndef directive
#ifndef __utility/EPD_H_
^
C:\Program Files (x86)\Arduino\libraries\EPD\src/EPD.h:2:18: warning: ISO C++11 requires whitespace after the macro name

使用记事本打开EPD.h库，好像出错的就是第一和第二行
