这是我用的铁牛单片机开发板里面的跑马灯程序。不知道能不能给你一些启发。灯是共阳的。给低电平亮。

4.多功能流水灯的设计
从原理图可以看出，如果我们想让接在P1.0口的LED1亮起来，那么我们只要把P1.0口的电平变为低电平就可以了；相反，如果要接在P1.0口的LED1熄灭，就要把P1.0口的电平变为高电平就可以；同理，接在P1.1~P1.7口的其他7个LED的点亮和熄灭方法方法同LED1。因此，要实现流水灯功能，我们只要将LED2~LED8依次点亮、熄灭，依始类推，8只LED变会一亮一暗的做流水灯了。
实现8个LED流水灯程序用中文表示为：P1.0低、延时、P1.0高、P1.1低、延时、P1.1高、P1.2低、延时、P1.2高、P1.3低、延时、P1.3高、P1.4低、延时、P1.4高、P1.5低、延时、P1.5高、P1.6低、延时、P1.6高、P1.7低、延时、P1.7高、返回到开始、程序结束。
从上面中文表示看来实现单片机流水灯很简单，但是我们不能说P1.0你变低，它就变低了。因为单片机听不懂我们的汉语的，只能接受二进制的“1、0。。”机器代码。我们又怎样来使单片机按我们的意思去工作呢？为了让单片机工作，只能将程序写为二进制代码交给其执行；早期单片机开发人员就是使用人工编写的二进制代码交给单片机去工作的。今天，我们不必用烦人的二进制去编写程序，完全可以将我们容易理解的“程序语言”通过“翻译”软件“翻译”成单片机所需的二进制代码，然后交给单片机去执行。这里的“程序语言”目前主要有汇编语言和C语言两种；在这里我们所说的“翻译”软件，同行们都叫它为“编译器”，将“程序语言”通过编译器产生单片机的二进制代码的过程叫编译。前面说到，要想使LED1变亮，只需将对应的单片机引脚电平变为低电平就可以了。现在让我们将上面提到的8只LED流水灯实验写为汇编语言程序。
