51单片机流水灯C程序

1、51单片机流水灯C程序51单片机流水灯C程序4/451单片机流水灯C程序P0口控制，先奇数亮再偶数亮，循环三次；一个灯上下循环三次；两个分别从两边往中间流动三次；再从中间往两边流动三次；可是这个程序实现的应当是这样的先奇数亮再偶数亮，循环三次；一个灯上下循环三次；两个分别从两边往中间流动；再从中间往两边流动（延时0.1s）#include#include#defineuintunsignedint#defineucharunsignedcharvoiddelay();voidmain()uchartemp,temp1,temp2,a,b;while(1)for(b=3;b0;b-)temp=0

3、0;b0;b-);程序实现的第2种方法:实现单片机led流水灯从中间向两边，从两边向中间的见效，下边的程序就是实现思路，这个是直接调用，应当理解吧,数组那其实也能够改一下，如采纳一维数组，在多次调用；也能够采纳二维数组。#include#defineuintunsignedint#defineucharunsignedcharucharTABLE=0 xFF,0 xE7,0 xC3,0 x81,0 x00,/从中间向双侧点亮0 xFF,0 xE7,0 xC3,0 x81,0 x00,0 xFF,0 xE7,0 xC3,0 x81,0 x00,0 xFF,0 x7E,0 x3C,0 x18,0
