这个是液晶模块1602A用于单片机AT89S52的C语言驱动头文件.这个头文件不是普通的头文件，笔者在其中加进了很多自己的东西。而且经过自己的实际验证是可以用的。 　　有了该文件，你可以不用看1602的DATASHEET就会使用。-This is a LCD module 1602A for the single-chip AT89S52 the C language driver header file. This header file is not an ordinary header files, in which the author added a lot of our own things. But after their own actual authentication can be used. With the file, you can not watch the 1602 will be used DATASHEET.
