单片机广告灯图案

Ⅰ 用单片机进行广告灯的控制

public int testException_finally(){
int x;
try {
x = 1;
//int y = 1/0; //放开此处，出现ArithmeticException。

/*//注释掉 int y = 1/0;处，放开此处，出现NullPointerException
String str = null;
str.substring(0);
*/
return x;
} catch (ArithmeticException e) {
x =2;
return x;
} finally{
x = 3;
}

Ⅱ 单片机课程设计 广告灯 求C语言的

#include<reg52.h>
void delayMs(unsigned char m); //函数声明void delayUs2x(unsigned char t);
void delay1s(unsigned int r);
/*------------------------------------------------
主函数
------------------------------------------------*/
void main (void)
{

unsigned char i;
unsigned char temp;//临时转换变量
while (1)
{
for(i=0;i<4;i++) //for循环，执行4次

{ P1=0xff; //LED全灭
delay1s(1);
P1=0x00; //LED全亮
delay1s(1);
}
temp=0xfc; //11111100
P1=temp;
for(i=0;i<7;i++) //for循环，执行7次
{
delay1s(1); //调用1s延时程序

temp<<=1; //移位
temp=temp|0x01;
}

}}
/*------------------------------------------------
μs级延时函数
------------------------------------------------*/
void delayUs2x(unsigned char t)
{
while(--t);
}
/*------------------------------------------------
mS级延时函数
------------------------------------------------*/
void delayMs(unsigned char m)
{

while(m--)
{
//大致延时1mS
delayUs2x(245);
delayUs2x(245);
}
}
/*------------------------------------------------
s级延时函数
-------------------------------------------------*/
void delay1s(unsigned int r)
{
while(r--)
{
//大致延时1s
delayMs(1000);
delayMs(1000);
}
}

Ⅲ 单片机控制广告灯课题设计程序

#include<reg51.h>
unsigned char time=0;

void delay(unsigned long w)
{
while(w--);
}

void zuoxunhuan()
{
unsigned char C;

for(C=0x80;C!=0;C>>=1) //左移
{
P1=C;
delay(30000);
}
}

void youxunhuan()
{
unsigned char C;

for(C=0x01;C!=0;C<<=1) //右移
{
P1=C;
delay(30000);
}
}

void zengti() //递增
{
unsigned int C;

for(C=0xFE;C!=0;C<<=1)
{
P1=~C;
delay(30000);
}
}

void jiaoti() //交替
{

P1=0x55;
delay(30000);
P1=0xaa;
delay(30000);
}

void init_init()
{
EX0=1;
EA=1;
}

void into_into() interrupt 0 //P3.2外接一个按键底电瓶有效切换程序
{
if((time+=1)==5) time=0;
delay(400000);
}

void main()
{
init_init();
while(1)
{
if(time==1) zuoxunhuan();
if(time==2) youxunhuan();
if(time==3) zengti();
if(time==4) jiaoti();

if(time==0)
{
zuoxunhuan();
youxunhuan();
zengti();
jiaoti();
}
}
}
