單片機日歷

2. 關於單片機日歷時鍾C編程

我寫的程序，自己移植一下吧，應該看得懂
閏年計算：
uint8 isleapyear(uint16 year)
{
if(((year%400)==0)||(((year%4)==0)&&(year%100)==0))
{
return 1;
}
else
return 0;
}

下面是按月計算日的最大值,每次mon變化計算一次就行了。
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單片機製做日歷

看看這個程序嘛，，雖然沒有你要得年月日，但是有時間得啊。。。可以藉此來點靈感。。我也在做這個東西。。。我還在收集資料啊。。。共同學習。。
;採用8位LED軟體解碼動態顯示程序
;使用AT89C51單片機,12MHZ晶振,P0輸出欄位碼,P2口輸出位選碼,用共陽
;LED數碼管,P1.0為調時位選擇按鍵,P1.1為加1鍵,P1.2為減1鍵。
;片內RAM的70H到77H單元為LED數碼管的顯示緩沖區
;78H,79H,7AH分別為秒、分、小時計數單元
;7BH為50ms計數器,7CH為調時按鍵計數器

分給我吧，我不知道您要的是液晶時鍾還是數碼管的，但是我給你的是時鍾，日歷很好加，自己根據理解家上吧。希望對你有幫助。
