AT89C51单片机编程

这容易,程序如下:
#include //头文件 用的是12M晶振
#include
#define uchar unsigned char
#define out P1

uchar code table1[]={0x7E,0x3C,0x18,0x81,0xC3,0xE7,0xFF,0xE7};
uchar j=0;

void delay(uchar ms) //延时
{
uchar j;
while(ms--)
{
for(j=0;j<250;j++)
{;}
}
}

void main()
{
out=0x00;
LOOP:
out=table1[j];
j++;
if(j>=8)j=0;
delay(200); //延时200mm
goto LOOP;
}

把8个状态放到数组里，每次取1个送到端口，就这样循环取呗。应该先学习一下单片机入门教程

最好学习单片机C语言，汇编的不好学
