C51单片机开发心形灯流水灯（C语言）

利用Keil uVision4编程程序，在Proteus 8 Professional中创建仿真电路

仿真电路

16进制样式花型

int a[][8] = {  0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80,0x03,0x06,0x0c,0x18,0x30,0x60,0xc0,0x80,0x07,0x0e,0x1c,0x38,0x70,0xe0,0xc0,0x80,0x0f,0x1e,0x3c,0x78,0xf0,0xe0,0xc0,0x80,0xfc,0xf9,0xf3,0xe7,0xcf,0x9f,0x3f,0x7f,};

延迟函数

void delay(unsigned int x)
{while(x--);
}

循环调用函数

led1() 是指操作P0端口，

以此类推，led4() 是调用四个输出端口，循环闪烁

void led1(int j,int i)
{while(1){P0 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P0 = 0x00;break;                }}while(1){P2 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P2 = 0x00;break;}}while(1){P3 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P3 = 0x00;break;}}while(1){P1 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P1 = 0x00;break;}}
}void led3(int j,int i)
{while(1){P0 = P2 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P0 = P2 = 0x00;break;}}while(1){P2 = P3 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P2 = P3 = 0x00;break;}}while(1){P3 = P1 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P3 = P1 = 0x00;break;}}while(1){P1 = P0 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P1 = P0 = 0x00;break;}}
}void led2(int j,int i)
{while(1){P0 = P3 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P0 = P3 = 0x00;break;}}while(1){P2 = P1 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P2 = P1 = 0x00;break;}}while(1){P3 = P0 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P3 = P0 = 0x00;break;}}while(1){P1 = P2 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P1 = P2 = 0x00;break;}}
}void led4(int j,int i)
{while(1){P0 = P2 = P3 = P1 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P0 = P2 = P3 = P1 = 0x00;break;}}while(1){P0 = P2 = P3 = P1 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P0 = P2 = P3 = P1 = 0x00;break;}}   while(1){P0 = P2 = P3 = P1 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P0 = P2 = P3 = P1 = 0x00;break;}}   while(1){P0 = P2 = P3 = P1 = a[j][i];delay(m);i++;if(i >= 8){i = 0;P0 = P2 = P3 = P1 = 0x00;break;}}}
