在学校的时候就玩了，根本没怎么用心学，现在只好自学，今天是起步，做了个简单的流水灯程序，记录一下，同时鞭策自己。

开发板是KingST的，编程软件是keil，下载时STC-ISP，下面是程序

#include

sbit ADDR0 = P1^0;

sbit ADDR1 = P1^1;

sbit ADDR2 = P1^2;

sbit ADDR3 = P1^3;

sbit ENLED = P1^4;

void main()

{

/*方法一：流水灯左移

unsigned int i=0;

ENLED = 0;

ADDR3 = 1;

ADDR2 = 1;

ADDR1 = 1;

ADDR0 = 0;

while(1)

{

P0 = 0xFE;

for(i=0;i<30000;i++);

P0 = 0xFD;

for(i=0;i<30000;i++);

P0 = 0xFB;

for(i=0;i<30000;i++);

P0 = 0xF7;

for(i=0;i<30000;i++);

P0 = 0xEF;

for(i=0;i<30000;i++);

P0 = 0xDF;

for(i=0;i<30000;i++);

P0 = 0xBF;

for(i=0;i<30000;i++);

P0 = 0x7F;

for(i=0;i<20000;i++);
