1基于单片机的液晶（LCD)图文显示系统设计摘要本文选用的是液晶显示控制器的芯片Ampire128×64，这是建立在单片机AT89C51的基础之上，并且围绕的主线是单片机LCD液晶显示系统控制器。主要实现汉字显示与图像显示，还介绍了芯片的设计部分与外部电路，并用系统方框图来说明，重点介绍了应用该系统的各硬件接口模块的功能及工作过程，并详细阐述了程序的各个模块。因为C语言指令的执行速度快且节省存储空间，所以本文设计采用的是单片机C语言进行软件设计。该软件设计采用的是模块化设计这样会有利于扩张和更改，而且对于程序设计的逻辑关系而言，这样会使得它看上去更加简洁明了，软件协调的控制硬件运行。另外部分程序的流程图和实现过程将会被说明出来。本文撰写的主导思路是建立在硬件的基础之上，采用软、硬件相结合的方式，来对各功能模块进行编写。最后，我设计的思想是软件和硬件调试的单片机LCD显示器的控制原理进行了详细的讨论。关键字：液晶显示器、89C51单片机、Ampire128×642Liquidcrystal(LCD)displaysystembasedongraphicdesignAbstractThispaperistheselectionofLCDcontrollerchipampire128*64,isbasedonsinglechipmicrocomputerAT89C51,AndaroundthemainlineisthemicrocontrollerLCDcontroller.ThemainachievementofChinesecharacterdisplayandimagedisplay,Italsodescribesthedesignofthechipandtheexternalcircuit,andusethesystemblockdiagramtoillustratetheapplicationfocusesonthefunctionofeachofthesystem'shardwareinterfacemodulesandworkingprocesses,andelaboratesthevariousmodulesoftheprogram.BecausetheClanguageinstructionexecutionspeedandsavethememoryspace,sothisdesignisadoptedtodesignthesoftwareofsinglechipClanguage.Thesoftwareisdesignedusingamodulardesign,whichwillfacilitatetheexpansionandchange,butalsoforlogicprogrammingisconcerned,thiswillmakeitlookmoreconcise,coordinatedcontrolhardwaretorunthesoftware.Anotherpartoftheflowchartofprogramandtherealizationoftheprocesswillbedescribed.Asofthiswritingthedominantideaisbuiltonthebasisofhardware,usingsoftwareandhardwarecombinationtobewrittenforeachfunctionalmodule.Finally,IthoughtthedesignprincipleistocontrolthesoftwareandhardwaredebuggingMCULCDmonitorswerediscussedindetail.Keywords:Liquidcrystal、display89C51、ampire128×64I目录第一章引言..................................................................................................................................11.1课题的研究背景................................................................................................................11.2课题的提出及研究意义....................................................................................................11.3论文的主要任务和所做的工作........................................................................................1第二章系统方案设计.....................................................................................................................32.1电路硬件设计原理图........................................................................................................3电路硬件设计原理图如图2-1所示。...................................................................................32.2软件设计方案...................................................................................................................32.3仿真结果............................................................................................................................4第三章硬件电路设计...................................................................................................................63.1单片机模块设...
