1、吉林大学论文题目基于单片机的简易电子时钟设计班级：xxxxxx专业：电子信息工程学生姓名：xxxx指导教师：xxxx日期：xxxx-xx-xx摘要数字钟已成为人们日常生活中必不可少的必需品，广泛用于个人家庭以及办公室等公共场所，给人们的生活、学习、工作、娱乐带来极大的方便。由于数字集成电路技术的发展和采用了先进的石英技术，使数字钟具有走时准确、性能稳定、携带方便等优点，它还用于计时、自动报时及自动控制等各个领域。尽管目前市场上已有现成的数字钟集成电路芯片出售，价格便宜、使用也方便，但鉴于单片机的定时器功能也可以完成数字钟
2、电路的设计，因此进行数字钟的设计是必要的。在这里我们将已学过的比较零散的数字电路的知识有机的、系统的联系起来用于实际，来培养我们的综合分析和设计电路，写程序、调试电路的能力。单片机具有体积小、功能强可靠性高、价格低廉等一系列优点，不仅已成为工业测控领域普遍采用的智能化控制工具，而且已渗入到人们工作和和生活的各个角落，有力地推动了各行业的技术改造和产品的更新换代，应用前景广阔。关键字：单片机，数字时钟。AbstractDigitalclockhasbecomeanindispensablenecessitiesinPeop
