代码说明:

该程序时是用12864液晶显示4*4矩阵键盘的按键值的,键盘按键值采用啄行扫描法扫描按键值。将按键值返回单片机,再通过12864液晶字符显示显示出来

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    本教程主要讲述计算机指令运行机制及汇编语言的相关知识,并用详实的例子来讲解如何使用O汇编语言来编写程序。汇编语言是计算机低级语言,它直接对应的是计算机机器指令,据有执行高效的特点,但由于它的底层性,指令浩繁复杂,如果你熟悉如MASM、FASM或者NASM等其它的汇编语言,那么你将能够很容易地学会使用O语言,它的内部机制与其它汇编语言是一致的;如果你没有接触过汇编语言,那么本教程将为你打开计算机语言的大门,深入细致地解剖聪明的计算机大脑的思考轨迹。如果你使用过C或者其它的计算机语言将对学习O语言有一定的帮助。-the handbook focuses on the operation of computer instructions and mechanisms related to the compilation of language knowledge, and the use of detailed examples to explain how to use the O Series language programming. Language is a compilation of computer low level language, which directly correspond to the computer machinery orders, according to the efficient implementation of the characteristics But since they are bottom, voluminous complex instructions, if you are familiar with such as Shape, FASM or Assemble the compilation and other languages, then you will be able to easily learn how to use O language, The internal mechanism and the other assembly language is unanimous; If you had any contact with assembly language. Then you ha
