51單片機(jī)流水燈C程序

1、51單片機(jī)流水燈C程序51單片機(jī)流水燈C程序4/451單片機(jī)流水燈C程序P0口控制，先奇數(shù)亮再偶數(shù)亮，循環(huán)三次；一個(gè)燈上下循環(huán)三次；兩個(gè)分別從兩邊往中間流動三次；再從中間往兩邊流動三次；可是這個(gè)程序?qū)崿F(xiàn)的應(yīng)當(dāng)是這樣的先奇數(shù)亮再偶數(shù)亮，循環(huán)三次；一個(gè)燈上下循環(huán)三次；兩個(gè)分別從兩邊往中間流動；再從中間往兩邊流動（延時(shí)0.1s）#include#include#defineuintunsignedint#defineucharunsignedcharvoiddelay();voidmain()uchartemp,temp1,temp2,a,b;while(1)for(b=3;b0;b-)temp=0
