LED显示屏控制技术与硬件电路设计VIP免费

摘要当今世界，电子技术迅猛发展，点阵式显示器件作为现代信息显示的重要媒体，在金融证券、体育、机场、交通、商业、广告宣传、邮电电信、指挥调度、国防军事等许多领域中得到了广泛应用。因此点阵式显示器件的研制、生产也的到了迅速的发展，并逐步形成产业，成为光电子行业的新兴产业领域。由于LED电子显示屏具有所显内容信息量大,外形美观大方,操作使用方便灵活.适用于火车,汽车站,码头,金融证券市场,文化中心,信息中心体育设施等公共场所.该项目广泛涉及了计算机及电子技术中的电源技术,单片机技术,数据通讯技术,显示技术,存储技术,系统软件技术,接口及驱动等技术.我国经济发展迅猛,对信息传播有越来越高的要求.可以相信,LED电子显示屏以其色彩鲜亮夺目,大的显示信息量,寿命长,耗电量小,重量轻,空间尺寸小,稳定性高,易于操作,安装和维护等特点,将在社会经济发展中扮演越来越重要的角色。利用单片机对整个系统进行总体控制，进行显示所要显示的字符。显示方式分为三种：逐字显示、上滚显示、左滚显示，其中显示字模数据由单片机输入显存，点阵的点亮过程有程序控制，由驱动电路完成，点阵采用单色显示，该显示器电路的特点是：点阵的动态显示过程占用时间比较短，亮度比较高，而且亮度可以改变电阻进行调节。本文以Proteus为软件平台，设计制作一套51系列单片机实验系统。【关键词】单片机点阵LED电子显示屏AbstractIntoday'sworld,therapiddevelopmentofelectronictechnology,dot-matrixdisplaydeviceasamoderninformationdisplayoftheimportantmedia,inthefinancialsecurities,sports,airport,transportation,commercial,advertising,postandtelecommunications,commandandcontrol,nationaldefensemilitary,andmanyotherareashavebeenwidelyapplied.Sodot-matrixdisplaydevicesinthedevelopment,productionandtotherapiddevelopment,andgraduallyformedaoptoelectronicstradeindustry,thenewindustryfields.BecauseLEDelectronicdisplayhasshowninformativecontent,abeautifulappearance,convenientinoperationisflexible.Applytothetrain,busstation,wharf,financialsecuritiesmarket,culturalcenter,informationcentersportsfacilitiesinotherpublicplaces.Thisprojectinvolvesawidecomputerandelectronictechnologyofpowertechnology,singlechipmicrocomputer,datacommunicationtechnology,displaytechnology,storagetechnology,systemsoftwaretechnology,interfaceanddrivetechnology.China'seconomicdevelopmentofinformationtransmissionhasrapidly,andmoreandmorehighrequirements.CanbelievethatLEDelectronicdisplaybyitscolorbrightisdazzing,largedisplayinformation,longlife,smallpowerconsumption,lightweight,smallsize,highstability,space,easytooperate,installationandmaintenanceandothercharacteristics,inthesocialeconomydevelopmentwillplaymoreandmoreimportantrole.Usingsinglechipcomputerinoverallcontrolofthewholesystem,displayshouldshowthecharacters.Displaymodeisdividedintothreetypes:wordforworddisplay,rollingdisplay,left,whichshowsthatfontthatrollofmicrocomputerdatainputthevideomemory,bitmaplightenedprocesshasprogramcontrol,bydrivingcircuitiscompleted,themonochromaticshowthatthedotmatrixdisplaycircuitfeaturesare:dotmatrixthedynamicdisplayoftheprocesstaketimeisshort,brightnessishigher,andbrightnesscanchangeresistanceontheadjustment.Inthispaper,thesoftwareplatform,Proteusfordesignasetof51seriesSCMexperimentsystem.Keywords:SCMlatticeLEDelectronicdisplay目录一．引言···························································3二．LED概述·······················································41.LED电子显示屏概述·····················...
