毕业设计（论文）任务书题目：电子万年历的设计与实现任务与要求：设计一以单片机为核心控制的万年历，具有多项显示和控制功能。

要求：准确计时，以数字形式显示当前年月日、星期、时间；具有年月日、星期、时间的设置和调整功能；自行设计所需直流电源时间： 2010年9 月 27 日至 2010 年 11 月 23 日共 8 周所属系部：电子工程系摘要随着微电子技术的高速发展，单片机在国民经济的个人领域得到了广泛的运用。

单片机以体积小、功能全、性价比高等诸多优点，在工业控制、家用电器、通信设备、信息处理、尖端武器等各种测控领域的应用中独占鳌头，单片机开发技术已成为电子信息、电气、通信、自动化、机电一体化等专业技术人员必须掌握的技术。

而电子万年历作为电子类小设计不仅是市场上的宠儿，也是是单片机实验中一个很常用的题目。

因为它的有很好的开放性和可发挥性，因此对作者的要求比较高，不仅考察了对单片机的掌握能力更加强调了对单片机扩展的应用。

而且在操作的设计上要力求简洁，功能上尽量齐全，显示界面也要出色。

数字显示的日历钟已经越来越流行，特别是适合在家庭居室、办公室、大厅、会议室、车站和广场等使用，壁挂式LED数码管显示的日历钟逐渐受到人们的欢迎。

LED数字显示的日历钟显示清晰直观、走时准确、可以进行夜视，并且还可以扩展出多种功能。

所以，电子万年历无论作为比赛题目还是练习题目都是很有价值。
