LED点阵心形灯

程序如下：

#include<reg52.h>
#define uchar unsigned char
#define uint unsigned int
sbit wx=P1^2;
sbit dx=P1^3;

char code hang[]={0xff,0x93,0x01,0x01,
					0x83,0xc7,0xef,0xff};
char code xuanhang[]={0x01,0x02,0x04,0x08,
					0x10,0x20,0x40,0x80};

void delay(uchar xms)
{
	uint i,j;
	for(i=xms;i>0;i--)
		for(j=110;j>0;j--);
}

void main()
{			  
	uchar i;
	while(1)
	{
	for(i=0;i<8;i++)
	{
	wx=1;
	P0=xuanhang[i];
	wx=0;
	P0=0;
	delay(1);

	dx=1;
	P0=hang[i];
	dx=0;
	P0=1;
	delay(1);
	}
	}		
}

仿真如下：

若想让心滚动起来（从下往上滚动），程序如下：

#include<reg52.h>
#define uchar unsigned char
#define uint unsigned int
sbit wx=P1^2;
sbit dx=P1^3;

char code hang[]={0xff,0x93,0x01,0x01,0x83,0xc7,0xef,0xff,0xff,0x93,0x01,0x01,
0x83,0xc7,0xef,0xff};
char code xuanhang[]={0x01,0x02,0x04,0x08,
0x10,0x20,0x40,0x80};

void delay(uchar xms)
{
	uint i,j;
 for(i=xms;i>0;i--)
 	for(j=110;j>0;j--);
}

void main()
{
	uchar i;
	uchar d=0,j=50;
	while(1)
	{
	while(j--)
	{
	for(i=0;i<8;i++)
	{
	wx=1;
	P0=xuanhang[i];
	wx=0;
	P0=0xff;
	dx=1;
	P0=hang[i+d];
	dx=0;
	P0=0x00;
	delay(1);
	}
	}
	d++;
	j=50;
	if(d==8)
	d=0;
	}
}
