单片机日历

2. 关于单片机日历时钟C编程

我写的程序，自己移植一下吧，应该看得懂
闰年计算：
uint8 isleapyear(uint16 year)
{
if(((year%400)==0)||(((year%4)==0)&&(year%100)==0))
{
return 1;
}
else
return 0;
}

下面是按月计算日的最大值,每次mon变化计算一次就行了。
switch(mon)
{
case 1:
case 3:
case 5:
case 7:
case 8:
case 10:
case 12:
{
daymax = 31;
}break;
case 4:
case 6:
case 9:
case 11:
{
daymax = 31;
}break;
case 2:
{
daymax = 28+isleapyear(year);
}break;

7. 51单片机制做日历

看看这个程序嘛，，虽然没有你要得年月日，但是有时间得啊。。。可以借此来点灵感。。我也在做这个东西。。。我还在收集资料啊。。。共同学习。。
;采用8位LED软件译码动态显示程序
;使用AT89C51单片机,12MHZ晶振,P0输出字段码,P2口输出位选码,用共阳
;LED数码管,P1.0为调时位选择按键,P1.1为加1键,P1.2为减1键。
;片内RAM的70H到77H单元为LED数码管的显示缓冲区
;78H,79H,7AH分别为秒、分、小时计数单元
;7BH为50ms计数器,7CH为调时按键计数器

分给我吧，我不知道您要的是液晶时钟还是数码管的，但是我给你的是时钟，日历很好加，自己根据理解家上吧。希望对你有帮助。
