STC89C52RC单片机万年历设计+程序+电路图

摘要近些年来我国科技发展有了重大的进步，人们的生活受到科技进步所带来的影响越来越大，随着人们对时间观念的重视，万年历的研发也有了迅速发展的机会。本设计针对这种现象设计出了一款具备多功能的液晶显示万年历设计，本次设计的液晶显示万年历除了具备普通的日期时间校准功能外，还具有着定点报时功能以及闹钟提醒功能以及当前温度环境检测功能。当使用者设置了闹钟到点之后液晶显示万年历会进行声光的提示。这些功能的实现主要依靠单片机 STC89C52RC为核心元件来完成控制，同时结合温度采集模块DS18B20芯片、12864液晶显示模块、扬声器以及LED指示灯共同组合成系统的硬件电路。在课题的设计方法上，本论文采用了层次分明的模块化设计，通过原理图和流程图的形式对各模块的硬件和软件设计原理和方法进行了详细的描述，通过最后的成果分析本系统适合推向未来智能日历市场，相比于旧产品具有更低的成本和更高的性能。软件设计上通过keil软件采用C语言程序进行设计，结合proteus仿真软件最终完成软硬件仿真调试，达到任务要求的目的。74971
