```c#include <reg51.h>#include <intrins.h>typedef unsigned char u8;typedef unsigned int u16;unsigned int sex;unsigned int sec;unsigned int T0count;unsigned int T0count1;#define led P2 u8 tap[] = {0xfe,0xfb,0xef,0xbf};u8 tap1[] = {0x.

在这#include <reg51.h>#include <intrins.h> typedef unsigned char u8;typedef unsigned int u16; sbit SRCLK=P3^6;sbit RCLK=P3^5;sbit SER=P3^4; u8 code ledduan[][8]={{0x00,0x00,0x72,0x51,0x51,0x51,0x4e,0x00}, //5 {

51流水灯实验（改)51单片机流水灯可以通过移位函数_crol_、移位运算符、数组等方法来实现。看原理图普通的51单片机开发板的LED模块的灯都是通过接电阻与单片机的IO口直接相连，一般连在P2口上也有其他IO口等等，写代码前要先看原理图灯连在哪里。我的是连在P2上，如图：图片: 代码如下#include "reg52.h" #include<intrins.h> //包含移位函数的头文件typedef unsigned char u8;#define led P2 //
