摘要:LCD液晶显示已经是人机界面的关键技术。本文对基于单片机的LCD液晶显示器控制系统进行了研究。首先在绪论中介绍了本课题的课题背景、研究意义及完成的功能。本系统是以单片机的基本语言汇编语言来进行软件设计，指令的执行速度快，节省存储空间。为了便于扩展和更改，软件的设计采用模块化结构，使程序设计的逻辑关系更加简洁明了。使硬件在软件的控制下协调运作。正文中首先简单描述系统硬件工作原理，且附以系统硬件设计框图，并介绍了单片机微处理器的发展史，论述了本次毕业设计所应用的各硬件接口技术和各个接口模块的功能及工作过程, 并描述了8052、8279及SED1520外接电路接口的软、硬件调试。其次阐述了程序的流程和实现过程。本文撰写的主导思想是软、硬件相结合，以硬件为基础，来进行各功能模块的编写。最后对我所开发的用单片机实现LCD液晶显示器控制原理的设计思想和软、硬件调试作了详细的论述。

Abstract
The LCD manifestation has been the key technique of the man-machine interface. This text to basic proceeded the research in Micro Controller Unit liquid crystal display control system. Introduced the lesson a background of this lesson and study meaning and finished functions in introduction first. This system edits collected materials the language to proceed with single the basic language of a machine the software designs, the instruction carries out the speed quick, save memory. For the sake of easy to expand with the design adoption mold a logic for turning construction, making procedure designing relation that change, software more shorter and more easier to understand. Make hardware control in software descended to moderate the operation. The text inside describes the system hardware work principle in brief first, and attach with the system hardware design frame diagram, combine development history that introduced the single a machine microprocessor, discuss this graduate design a function for applied each hardware connecting a people the technique connects with each one a mold piece and work processes, combine to describe in a specific way 8052,8279 and the SED1520 circumscribes the electric circuit connects oscular and soft, the hardware adjusts to try. Expatiated the process of the procedure the next in order with realizes process. The predominance thought that this text compose is soft, the hardware combines together, regarding hardware as the foundation, proceed the plait of each function mold piece write. Develop to me finally of use the single a machine realizes the design thought that the liquid crystal display of LCD control principle with soft, the hardware adjusted to try to make the detailed treatise.
