LED立方体显示器设计

摘要LED是发光二极管(LightEmittingDiode)的简称。有它产生的LED显示屏，在高速发展的信息社会中，不再是公共信息展示的作用，也越来越贴近于商业化应用。例如，图形和文字的静态显示，实时信息的动态显示和处理，另外，不仅有二维显示，还有三维立体的展示，就像光立方。LED具有的良好特性，使光立方的开发越来越完善。随着它的性能越来越好，其应用领域将会越来越广。本次研究课题：设计一个立方体显示器，主要任务及目标为：光立方的比例是8*8*8，能显示圆锥体等立体结构，各面能显示基本字符。在此基础上的预期效果：光立方能显示更多的趣味图形，并能显示流动的文字和图案，最终组合成动画。如果想自定义图形和文字，可以通过编程去实现，最终能在光立方上得到完美的呈现。关键词：光立方；LED立方体显示器；LED动画iAbstractLEDisshortforlight-emittingdiodes.ItproducestheLEDdisplay.Intherapiddevelopmentoftheinformationsociety,theLEDdisplayisnolongertheroleofpublicinformationdisplay,andgetclosertocommercialapplication.Forexample,imageandtextsstaticdisplay,dynamicdisplayandprocessingofreal-timeinformation.Inaddition,Itisnotonlythetwo-dimensionaldisplay,aswellasthree-dimensionaldisplay,likelightcube.LEDhasgoodcharacteristicsandmakethedevelopmentoflightcubebecomemoreperfect.WithItsperformanceisgettingbetterandbetter,anditsapplicationswillbemorewidely.Theresearchproject:designacubedisplay,themaintasksandobjectives:theproportionoflightcubeis8*8*8andcandisplaythree-dimensionalstructuressuchasconesandeachsidecanshowthebasiccharacters.Onthisbasis,thedesiredeffect:thelightcubecandisplaymoreinterestingimages,andcanshowtheflowofwordsandimages,andultimatelycombinedintoanimation.Ifyouwanttocustomizethewordsandimages，Youcanachievebyprogramming,finallyabletogettheperfectpresentonthelightcube.Keywords:LightCube;LEDCubedisplay;LEDanimationii目录摘要.1Abstract.2前言.3第一章绪论.41.1开发背景.41.2所要完成的工作.4第二章光立方系统设计.52.1光立方整体结构.52.2显示程序的设计流程.52.3工作原理.6第三章元器件选择.83.1STC12C5A60S2芯片.83.274HC573芯片.83.3ULN2803芯片.103.4LED灯.10第四章制作与调试.114.1主控电路.114.2驱动电路.124.3显示模块.134.4调试.144.5效果展示.14第五章总结与展望.165.1总结.165.2展望.17参考文献致谢附录（程序）0前言为了更好的显示效果，本设计采用方形蓝色雾灯，相间2cm，构成8*8*8的立方体。它由核心处理器送出信息，驱动电路工作，最终完成光立方显示。采用C语言编程，编程好的程序烧录到芯片中，利用数组变化来控制LED灯亮灭，从而使得LED灯显示不同的图案，通过信息锁存达到文字图案的静态显示。再在每个图案数组间加入延时语句来控制LED灯点亮时间，从而使LED组成的图案转换起来，由于人眼特性，只要图案与图案转换时间较小，人眼就能忽视其时间间隔，从而能看到不同形状的图案不断转换，流动性的立体显示动画，看起来生动美观。全文共分为五章。第1章绪论主要介绍了本设计的开发背景，国内外现况及本设计所要完成的工作。第2章介绍了主要元件。第3章介绍了光立方的整体结构以及工作原理。第4章制作与调试。教大家如何焊接整齐的光立方，以及做成后的效果图。第5章课题总结与展望。1第一章绪论1.1开发背景光立方技术的出现一直到现在仍然被很多人所热爱，它相对于传统的显示器，立体感更好。然而，随着人们生活水平的提高，对于光立方的要求也随着提高，不再只是室内，它的高适应性让它应用于室外，例如广告牌等的现实的效果更佳美幻多彩，吸引了众多眼球。给商家带来了利益，也给大众带来了美好的视觉盛宴。就在新中国成立六十周年晚会上，光立方成就了经典。那由众多LED灯组成的“五星红旗”飘扬的动感画面，还有那八千多只“小白鸽”，在夜空中飞翔的壮观景象，似是真的，给光立方更多的延伸空间。至此，人们对于光立方有了更多的追捧与热爱，促使光立方技术在不断更新与进步，这种光立方技术，在近期被广泛应用于大型演唱会，城市地标广场等场合。1.2所要完成的工作本次毕业设计的课题是完成LED立方体显示器设计，要求：比例8*8*8，能显示圆锥体等立体结构，各面能显示基本字符。预期要求是完成课题要求的情况下，能实现图形或者文字的动态旋转，移入移出等显示方式，并尝试显示器的频谱显示输出。2第二章光立方系统设计2.1光立方整体结构图2-1光立方整体结构图由图可知：要让光立方显示，从两部分入手，首先是行驱动器控制8个层面的灯亮灭，再是列驱动器控制8个竖面的灯亮灭，最后结合行列信息，把图案文字在光立方上显示出来。这里的STC12C5A60S2就是主控芯片，列驱动器是74HC573芯片构成的电路，行驱动器是ULN2803达林顿管构成的电路。2.2显示程序的设计流程图2-2显示程序设计流程图3显示程序如下：voidmain()sinter();/clear(0);while(1)clear(0);flash_2();flash_3();flash_4();flash_4();flash_5();flash_5();flash_6();flash_7();flash_8();flash_9();flash_10();clear(0);flash_11();flash_9();flash_5();flash_7();flash_5();flash_6();flash_8();flash_9();flash_10();voidprint()interrupt1uchari;staticucharlayer=0;P1=0;for(i=0;i#include#defineucharunsignedchar#defineuintunsignedintuchardisplay88;/*rank:I,心,U*/ucharcodetable_cha88=0x51,0x51,0x51,0x4a,0x4a,0x4a,0x44,0x44,0x18,0x1c,0x18,0x18,0x18,0x18,0x18,0x3c,0x3c,0x66,0x66,0x30,0x18,0xc,0x6,0xf6,0x3c,0x66,0x60,0x38,0x60,0x60,0x66,0x3c,0x30,0x38,0x3c,0x3e,0x36,0x7e,0x30,0x30,0x3c,0x3c,0x18,0x18,0x18,0x18,0x3c,0x3c,0x66,0xff,0xff,0xff,0x7e,0x3c,0x18,0x18,0x66,0x66,0x66,0x66,0x66,0x66,0x7e,0x3c;/*theideasoft*/ucharcodetable_id40=0x81,0xff,0x81,0x00,0xff,0x81,0x81,0x7e,0x00,0xff,0x89,0x89,0x00,0xf8,0x27,0x27,0xf8,0x00,0x8f,0x89,0x89,0xf9,0x00,0xff,0x81,0x81,0xff,0x00,0xff,0x09,0x09,0x09,0x01,0x00,0x01,0x01,0xff,0x01,0x01,0x00;/*railway*/ucharcodedat128=0x0,0x20,0x40,0x60,0x80,0xa0,0xc0,0xe0,0xe4,0xe8,0xec,0xf0,0xf4,0xf8,0xfc,0xdc,0xbc,0x9c,0x7c,0x5c,0x3c,0x1c,0x18,0x14,0x10,0xc,0x8,0x4,0x25,0x45,0x65,0x85,0xa5,0xc5,0xc9,0xcd,0xd1,0xd5,0xd9,0xb9,0x99,0x79,0x59,0x39,0x35,0x31,0x2d,0x29,0x4a,0x6a,0x8a,0xaa,0xae,0xb2,0xb6,0x96,0x76,0x56,0x52,0x4e,0x6f,0x8f,0x93,0x73,0x6f,0x8f,0x93,0x73,0x4a,0x6a,0x8a,0xaa,0xae,0xb2,0xb6,0x96,0x76,0x56,0x52,0x4e,0x25,0x45,0x65,0x85,0xa5,0xc5,0xc9,0xcd,0xd1,0xd5,0xd9,0xb9,0x99,0x79,0x59,0x39,0x35,0x31,0x2d,0x29,0x0,0x20,0x40,0x60,0x80,0xa0,0xc0,0xe0,0xe4,0xe8,0xec,0xf0,0xf4,0xf8,0xfc,0xdc,0xbc,0x9c,0x7c,0x5c,0x3c,0x1c,0x18,0x14,0x10,0xc,0x8,0x4;/*railway2*/ucharcodedat228=0x0,0x20,0x40,0x60,0x80,0xa0,0xc0,0xe0,0xe4,0xe8,0xec,0xf0,0xf4,0xf8,0xfc,0xdc,0xbc,0x9c,0x7c,0x5c,0x3c,0x1c,0x18,0x14,0x10,0xc,0x8,0x4;/*railway3*/ucharcodedat324=0x00,0x01,0x02,0x03,0x04,0x05,0x06,0x16,0x26,0x36,0x46,0x56,0x66,0x65,0x64,0x63,0x62,0x61,0x60,0x50,0x40,0x30,0x20,0x10;19/*3pchar*/ucharcodetable_3p38=0xff,0x89,0xf5,0x93,0x93,0xf5,0x89,0xff,0x0e,0x1f,0x3f,0x7e,0x7e,0x3f,0x1f,0x0e,0x18,0x3c,0x7e,0xff,0x18,0x18,0x18,0x18;/*initializtionThatistoinitializetheprogram.Itiswritetosetthetimerinc52mcu.Sotheprogramcanrenovatetheled_3d_cubeinfixedtimeusetheinterruptfunction.*/voidsinter()IE=0x82;TCON=0x01;TH0=0xc0;TL0=0;TR0=1;voiddelay5us(void)/误差-0.026765046296u
