单片机课程设计跑马灯

‘壹’ 如何用一个STC单片机做一个跑马灯，菜鸟一只，最好用详细的过程

# include <reg52.h>
# include <intrins.h> //循环左移右移函数

void delay1ms(unsigned int i)
{
unsigned char j;
while (i--)
{
for (j=0; j<115; ++j) //1ms基准延时程序
{
;
}
}
}

void main()
{
P0 = 0XFE; // P0灯
while (1)
{

P0 = _crol_(P0,1); // P0左移1位
delay1ms(100);
}

}
自己根据你的板子 改下参数

‘贰’ 单片机跑马灯课程设计从开始到结尾到底该怎么做！！！！！急

import java.applet.Applet;
import java.awt.Color;
import java.awt.Font;
import java.awt.FontMetrics;
import java.awt.Graphics;
import java.awt.Image;

public class Welcome extends Applet {
int pos = 0;
Image graph;
int w=0;
String str = "热烈欢迎2009届新生入学";
Font f = new Font("黑体", Font.BOLD, 20);
Color c=new Color(0,255,255);
public Welcome(){
FontMetrics fm = getFontMetrics(f);
w = fm.stringWidth(str);
pos=w;
}
public void paint(Graphics g) {
g.setFont(f);
g.setColor(c);
g.drawString(str, pos-w, 40);
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
pos = pos + 5;
if (pos-w > getWidth())
pos = w;
repaint();
}
}
