DS1302设计的可调万年历（实测正常，附有程序） - 图文

DS1302设计的可调万年历

（本制作所用数码管全为共阳数码管）

我刚开始想做万年历的时候是上网找别人的程序，可是发现找了很多都不理想，要不就没日历和时间一起显示，要不就不能调时间的，后来我研究了两天，自己终于把程序编了出来。好了，废话我就不多说，本制作我已经把实物做了出来，保证没问题！下面附有仿真图和实物图。

拍摄的效果不够好，但实物是不错的，本人实物中用三级管代替了仿真图的74HC04非门，用哪个都是可以的……

请注意：本程序分两个C文件的，如果不会编，可以Q我：1107588997 我直接发程序过去给你…… 软件源程序：(初始化程序只在开始时用一次，之后要把它屏蔽掉)
