单片机数字时钟设计摘要近年来随着计算机在社会领域的渗透和大规模集成电路的发展,单片机的应用正在不断地走向深入,由于它具有功能强,体积小,功耗低,价格便宜,工作可靠,使用方便等特点,因此特别适合于与控制有关的系统,越来越广泛地应用于自动控制,智能化仪器,仪表,数据采集,军工产品以及家用电器等各个领域,单片机往往是作为一个核心部件来使用,在根据具体硬件结构,以及针对具体应用对象特点的软件结合,以作完善。而51系列单片机是各单片机中最为典型和最有代表性的一种,通过本次课程设计进一步对单片机学习和应用,从而更熟悉单片机的原理和相关设计并提高了开发软、硬件的能力。本设计主要设计一个基于80C51单片机的电子时钟,并在LED上显示相应的时间,通过两个控制键和4×4键盘来实现时间的调节功能。应用Proteus软件实现单片机数字时钟系统的设计与仿真。关键词:单片机80C51数字时钟汇编语言AbstractWiththecomputerinthesocialsphereinrecentyears,thepenetrationandthedevelopmentoflargescaleintegratedcircuit,microcontrollerapplicationsareconstantlydeepening,becauseofitspowerfulfunction,smallsize,lowpowerconsumption,cheap,reliable,easytouseandsoonThereforeparticularlysuitedtoandcontrolofthesystem,moreandmorewidelyusedinautomaticcontrol,intelligentinstruments,gauges,dataacquisition,militaryproductsandhouseholdappliancesandotherfields,SCMisoftenusedasacorecomponentinAccordingtothespecifichardwarearchitecture,andapplication-specificsoftwarefeaturesobjectcombinetomakeperfect.The51seriesisthemosttypicalofthemicrocontrollerandthemostrepresentativeone,throughthiscoursedesignedtofurtherstudyandapplicationofmicrocontrollers,whicharemorefamiliarwiththeprinciplesofSCMandrelateddesignanddevelopmentofimprovedsoftwareandhardwarecapabilities.Thedesignofthemaindesignofa80C51microcontrollerbasedelectronicclock,andtheLEDdisplaythecorrespondingtime,bytwocontrolkeysand4×4keyboardtoachievetheregulatoryfunctionoftime.ProteussoftwareapplicationMCUdigitalclocksystemdesignandsimulation.Keywords:digitalclock80C51microcontrollerassemblylanguage
