常用接口电路及其编程
1. LED数码显示器的连接与编程
在单片机系统中，通常用LED数码显示器来显示各种数字或符号。由于它具有显示清晰、亮度高、使用电压低、寿命长的特点，因此使用非常广泛。
1. 八段LED显示器
引入：还记得我们小时候玩的“火柴棒游戏”吗，几根火柴棒组合起来，可以拼成各种各样的图形，LED显示器实际上也是这么一个东西。
-common programming interface and a circuit. LED digital display connections and programming in the SCM system, usually LED digital display to show figures or symbols. Because of its clear display and high brightness, the use of low-voltage, long-life characteristics, the use of very extensive. 1. Section 7 LED displays introduction : remember we were young playing the "match stick game"?, crossing a match stick combination, makes up all kinds of graphics, LED display is actually such a thing.
