摘要摘要本文介绍了基于STC89C52单片机的多功能电子万年历的硬件结构和软硬件设计方法。本设计由数据显示模块、温度采集模块、时间处理模块和调整设置模块四个模块组成。系统以STC89C52单片机为控制器，以串行时钟日历芯片DS1302记录日历和时间，它可以对年、月、日、时、分、秒进行计时，还具有闰年补偿等多种功能。温度采集选用DS18B20芯片，万年历采用直观的数字显示，数据显示采用1602A液晶显示模块，可以在LCD上同时显示年、月、日、周日、时、分、秒，还具有时间校准等功能。此万年历具有读取方便、显示直观、功能多样、电路简洁、成本低廉等诸多优点，具有广阔的市场前景。关键字：万年历温度计液晶显示IABSTRACTABSTRACTThispaperintroducesthebasedonSTC89C52multi-functionelectroniccalendarofthehardwarestructureandsoftwareandhardwaredesignmethod.Thisdesignbydatadisplaymodule,temperatureacquisitionmodule,timeprocessingmoduleandsetmodulefourmodules.WithSTC89C52single-chipmicrocomputersystemforthecontrollertoserialclockcalendarchipDS1302recordcalendarandtime,itcanbetodateandtime,minutesandsecondsforthetime,alsohasaleapyearcompensationandotherfunctions.TemperaturegatheringchooseDS18B20chip,calendarbyusingobjectdigitaldisplay,datashowedthatthe1602Aliquidcrystaldisplaymodule,canbeintheLCDshowsatthesametimeyear,month,day,Sunday,when,minutesandseconds,stillhavetimecalibrationetc.Function.Thiscalendarhasreadtheconvenient,directdisplay,functionaldiversity,simplecircuit,lowcost,andmanyotheradvantages,hasabroadmarketprospect.Keywords：PerpetualCalendarthermometerLCDdisplayII目录目录摘要......................................................IABSTRACT.................................................II前言......................................................V1绪论....................................................11.1课题研究的背景....................................11.2课题的研究目的与意义...............................11.3课题解决的主要内容.................................12系统的方案设计与论证....................................22.1单片机芯片设计与论证...............................32.2按键控制模块设计与论证.............................32.3时钟模块设计与论证.................................32.4温度采集模块设计与论证.............................42.5显示模块模块设计与论证.............................43系统硬件的设计..........................................53.1STC89C52单片机....................................53.2时钟芯片DS1302接口设计与性能分析..................83.3温度芯片DS18B20接口设计与性能分析................113.4LCD显示模块......................................153.5按键模块设计......................................173.6复位电路的设计....................................174系统的软件设计.........................................194.1主程序流程图的设计................................194.2程序设计.........................................205系统的机体设计.........................................245.1系统的模块组成....................................245.2功能实现.........................................24结论.....................................................26参考文献.................................................27致谢.....................................................28附录.....................................................29III前言前言随着科技的快速发展，时间的流逝,从观太阳、摆钟到现在电子钟，人类不断研究，不断创新纪录。目前，单片机技术的应用产品已经走进了千家万户。电子万年历的出现给人们的生活带来了诸多方便。随着微...
