课程设计说明书课程名称：电子课程设计设计题目：彩灯控制器班级：测控111姓名：学号：指导老师：设计时间：2013-7-8~~2013-7-17摘要:近年来，由于集成电路的迅速发展，使得数字逻辑电路的设计发生了根本性的变化。在设计中更多的使用中规模集成电路，不仅可以减少电路组件的数目，使电路简捷，而且能提高电路的可靠性，降低成本。因此用集成电路来实现更多更复杂的器件功能则成为必然。现代生活中，彩灯越来越成为人们的装饰品，它不仅美化环境，渲染气氛，还可以用于娱乐场所和电子玩具中去，现以该课题为例进行分析与设计可编程的彩灯控制的电路很多，构成方式和采用的集成片种类、数目更是五花八门，而且有专门的可编程彩灯控制电路。绝大多数的彩灯控制电路都是数字电路来实现，例如：用中规模集成电路实现的彩灯控制器主要用计时器、译码器、分配器和移位寄存器等集成。本次设计的可编程彩灯控制电路就是用计数器和译码器等来实现的。关键词：计数器；555定时器；发光二极管1.AbstractInrecentyears,duetotherapiddevelopmentcircuits,makedigitallogiccircuitdesignundergoneafundamentalchange.Inthedesignmoreusescaleintegratedcircuit,notonlycanreducethenumberofcircuitcomponents,thecircuit,andcanimprovethesimplicityofthecircuitreliability,reducethecost.Sowithintegratedcircuittoachievemorecomplexdevicefunctionisinevitable.Inmodernlifelanternhasbecomemoreandmorepeopleadornment,itnotonlycanbeautifytheenvironment,renderingatmosphere,itcanalsobeusedinentertainmentandelectronictoys,nowwiththistopicforexampleanalysisanddesignprogrammablelightscontrolcircuitmany,theformsandintegratedpiecetype,number,andmultifarioushasspecialprogrammablecircularlightscontrolcircuit.Mostofthelightscontrolcircuitrealizedwiththedigitalcircuits,forexample,usemediumscaleintegratedcircuitrealizedwiththelightscontrollermainlycounteranddecoder,distributorsandshiftregisterectintegration.Thedesignoftheprogrammablelightscontrolcircuitistouseregisters,counteranddecoder,ect.Torealize,itscharacteristicisusinglight-emittingdiodesdisplay,realizepresentprogrammingcircularfunction.Keywords:LED;Counter;ME555目录1．绪论···············································1······································2················································2················································2···············································23.总体方案设计········································3············································33.2总体设计原理···········································33.3总体设计元件···········································4···········
