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。

单片机万年历程序代码以下是一个示例单片机万年历的程序代码：```c#include <reg51.h>typedef unsigned char uchar;typedef unsigned int uint;sbit K1 = P2^0; // 显示年份sbit K2 = P2^1; // 显示月份sbit K3 = P2^2; // 显示日期uchar code year_tab[] = {31,28,31,30,31,30,31,31,30,31,30,31}; uchar code week_tab[] = {0x06,0x07,0x01,0x02,0x03,0x04,0x05}; uchar year, month, day, week;void delay(uint ms){uint i, j;for(i=ms;i>0;i--)for(j=110;j>0;j--);}uchar getKey(){if(K1==0) {delay(5);if(K1==0)return 1;while(!K1);}if(K2==0) {delay(5);if(K2==0)return 2;while(!K2);}if(K3==0) {delay(5);if(K3==0)return 3;while(!K3);}return 0;}void display(uchar num) {P0 = num;delay(1);P0 = 0x00;}void init(){TMOD=0x01;TH0=0xFC;TL0=0x67;EA=1;ET0=1;TR0=1;}void main(){init();while(1) {uchar key = getKey();if(key == 1) {year++;if(year == 100)year = 0;}else if(key == 2) {month++;if(month == 13)month = 1;}else if(key == 3) {day++;if(day > year_tab[month-1]) { day = 1;}}display(year / 10);display(year % 10);display(month / 10);display(month % 10);display(day / 10);display(day % 10);display(week);}}void timer0() interrupt 1{TH0=0xFC;TL0=0x67;week++;if(week == 7)week = 0;}```该代码的主要思路是通过外部三个按键模拟年、月和日的调节，通过一个定时器不断更新星期的计数，然后将年、月、日和星期分别在数码管上显示出来。
