1论文题目基于单片机的电子万年历（英文）DesignofElectronicCalendarbasedonsingleChipMicrocomputer摘要现今信息技术飞速发展,时间和每一个人都有非常密切的相互联系,时间对任何人都有着非常重要的影响。随着科技的快速发展，流逝的时间，我们从根据太阳来判断时间，发展到了用钟摆看时间，到现在又有了各种电子表等。当各类电子表在我们生活中广泛应用的时候，电子万年历的的出现又把我们引入到一个全新的时代。电子万年历是一种使用非常广泛的日常计时工具，对现代社会越来越流行。它可以对年、月、日、周日、时、分、秒进行计时，还具有闰年补偿等多种功能，还具有时间校准等功能。本设计是基于51系列的单片机进行的电子万年历设计，主要由时钟芯片DS1302采集数据到单片机进行处理再通过LCD1602显示出来。电子万年历的软件部分是使用c语言编写，主要用到的硬件电路有时钟芯片DS1302、液晶显示LCD1602，主控制芯片AT89C51，还有按键。关键词：单片机，LCD602，AT89C51，DS3022AbstractNowadaysinformationtechnologydevelopsrapidly,andtimeandeveryonehaveverycloseinterconnections,andtimehasaveryimportantinfluenceonanyone.Withtherapiddevelopmentofscienceandtechnology,thetimeelapsed,wejudgethetimeaccordingtothesun,developtousethependulumtowatchthetime,andnowhaveallkindsofelectronicwatchesandsoon.Whenallkindsofelectronicwatchesarewidelyusedinourlives,theadventofelectroniccalendarbringsustoawholenewera.Electroniccalendarisakindofwidelyuseddailytimingtool,whichisbecomingmoreandmorepopularinmodernsociety.Itcantimetheyear,month,day,Sunday,hour,minute,second,alsohaveleapyearcompensationandsoonmanyfunctions,stillhavetimecalibrationandsoonfunction.Thisdesignisbasedontheelectroniccalendardesignof51seriesofsingle-chipmicrocomputer,mainlybytheclockchipDS1302collectingdatatothesinglechipmicrocomputerforprocessingandthenthroughLCD1602.Thesoftwarepartoftheelectroniccalendariswritteninclanguage.ThemainhardwarecircuitsusedareclockchipDS1302,liquidcrystaldisplayLCD1602,mastercontrolchipAT89C51,andbuttons.Keywords:Microcontroller;LCD1602;AT89C51;DS1302目录目录....................................................................................................3第1章绪论......................................................................................41.1背景及目的.......................................................................................................431.1.1课题研究背景....................................................................................41.1.2选题的意义及目的............................................................................41.2国内外发展现状及水平...................................................................................4第2章系统的方案选择及论证......................................................62.1单片机芯片选择...............................................................................................62.2时钟芯片的选择与论证...................................................................................62.3显示模块的选择与论证...................................................................................62.4电路设计最终方案...........................................................................................7第3章系统的硬件设计与实现.......................................................83.1电路设计框图...................................................................................................83.2系统硬件概述....................................................................................
