追问

太帅啦！再问下啊，这个是用软件延时的，它体现在哪，调用子程序体现在哪吗？可以回答分就给你啦，不行就给你60%的分，可以吧？这是主程序
void main(void)
{
uchar i;
P0 = 0xff;
P2 = 0xff;

while(1)
for(i=0;i <110; i++)
{
P0 =display_P0[i];
P2 =display_P2[i];
delayms(200);
}
}

Answer 2

//这是一个花样流水灯控制程序，主程序没有，由数组值来控制
#include <reg51.h> //提供基本的51单片机端口定义
#include <intrins.h> //这个头文件主要提供移位控制函数
#define uchar unsigned char
#define uint unsigned int
uchar code display_P0[]={ //这个数组控制P0口花样流水灯的显示

Answer 3

看不懂，
你这仅仅是一段数据
还有一个不完整的延时子函数
连个主函数也没有
没人能看懂，
但是我却明白你可能要表达的意思
其实，同学，你用这种查表方式实现的流水灯，程序结构不太好
我认为还是用循环，移位等办法

OK

追问

void main(void)
{
uchar i;
P0 = 0xff;
P2 = 0xff;

while(1)
for(i=0;i <110; i++)
{
P0 =display_P0[i];
P2 =display_P2[i];
delayms(200);
}
}

Answer 4

没找到主函数~~ 数组里面写的是你想让跑马灯的跑法~~

追问

void main(void)
{
uchar i;
P0 = 0xff;
P2 = 0xff;

while(1)
for(i=0;i <110; i++)
{
P0 =display_P0[i];
P2 =display_P2[i];
delayms(200);
}
}

Answer 5

主函数呢？有意思

追问

void main(void)
{
uchar i;
P0 = 0xff;
P2 = 0xff;

while(1)
for(i=0;i <110; i++)
{
P0 =display_P0[i];
P2 =display_P2[i];
delayms(200);
}
}
