1、 I 摘摘 要要 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 C 语言来进行软件设计，51 的编程语言常用的有二种， 一种是汇编语言，一种是 C 语言。汇编语言的机器代码生成效率很高但可读性 却并不强，复杂一点的程序就更是难读懂，而 C 语言在大多数情况下其机器代 码生成效率和汇编语言相当，但可读性和可移植性却远远超过汇编语言，而且 C 语言还可以嵌入汇编来解决高时效性的代码编写问题。对于开发周期来说， 中大型的软件编写用 C 语言的开发周期通常要
2、小于汇编语言很多。综合以上 C 语言的优点，我在学习时选择了 C 语言指令的执行速度快，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, 并具体描述了 AT89C51 AMPIRE12864 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
