单片机万年历c

Ⅰ 单片机万年历的c语言程序

呵呵，这个东西我最近做过。也用过DS1302、PCF8563时钟芯片，还算比较简单啦。
只不过没这么多功能，这些日子正想做个跟手表一样多的功能。等做完了，发给你把。你加我的网络Hi吧。
我可以帮助你，你先设置我最佳答案后，我网络Hii教你。

Ⅱ C51单片机的万年历程序设计

我这有个数码管显示的程序
以前做的，。。
你可以在我这个程序上修改修改
包括键盘扫描，还有动态显示
。

Ⅲ 单片机做万年历用数码管的优缺点

优点，定时精准，缺点，电路复杂成本高。
数码管万年历的设计原理是利用AT89C5单片机内部定时/计数器TO的模式2（8位自动重装初值）产生一个时间为250us的信号，再计数4000次产生1S的时间后发出中断，再由单片机进行数据处理后，送人数码管（共阴极数码管）显示（动态显示）。

Ⅳ 基于51单片机制作万年历，用数码管，定时器，不用时钟芯片，不用液晶，怎么做求大神解，原理图和C程序

基于51单片机制作万年历，用两个8位一体的共阴数码管，显示日期和时间。数码管位选用两片74HC138，便于动态扫描显示，又节省引脚。用3个按键调时，K1为选择调时状态，K2为加1键，K3为减1键。

仿真图如下：
