用LED制作的万年历

  首先我们进行材料的准备:数码管
  上图中,年、月、日及时间选用的是1.2寸共阳数码管,星期选用的是2.3寸数码管,温度选用的是0.5寸数码管,也可根据个人的爱好选用不同规格的数码管。原理图如下图所示:电路原理图
  上图中,CPU选用的是AT89C2051,时钟芯片选用的是Dallas公司的DS1302, 温度传感器选用的是Dallas公司的数字温度传感器DS1820,显示驱动芯片选用的是德州仪器公司的TPIC6B595,也可选用与其兼容的芯片NC595或 国产的AMT9595。简单的原理解析:整个电子钟用两个键来调节时间和日期。一个是位选键,一个是数字调节键。按一下位选键,头两位数字开始闪动,进入设 定调节状态,此时按数字调节键,当前闪动位的数字就可改变。全部参数调节完后,五秒钟内没有任何键按下,则数字停止闪动,退出设定调节状态。
  源程序清单如下(无温度显示程序):
