点阵位置程序通常用于控制LED点阵屏的显示,可以通过不同的方式来实现。以下是几种常见的点阵位置程序编写方法:

方法一:使用C语言编写

```c

include

include

define uint unsigned int

define uchar unsigned char

uchar codetable[] = {0xff,0xfe,0xfd,0xfc,0xfb,0xfa,0xf9,0xf8}; // 列移数组

uchar codehaleda[] = {0x00,0x1f,0x28,0x48,0x48,0x28,0x1f,0x00}; // A行输出数组

uchar codehaledb[] = {0x00,0x36,0x49,0x49,0x49,0x7f,0x00,0x00};

uchar codehaledc[] = {0x00,0x00,0x22,0x41,0x41,0x41,0x3e,0x00};

uchar codehaledd[] = {0x00,0x00,0x1c,0x22,0x41,0x41,0x7f,0x00};

uchar codenian[] = {0x00,0x04,0x54,0x54,0x7f,0x54,0xdc,0x04};

uchar codeyue[] = {0x00,0xff,0x94,0x94,0xfe,0x01,0x00,0x00};

void delay(unsigned int m);

void main() {

uchar i, j, k;

P1 = 0x00;

P2 = 0x00;

P3 = 0x00;

while(1) {

for(i = 0; i < 8; i++) {

P2 = codetable[i];

for(j = 0; j < 8; j++) {

P1 = codehaleda[j];

delay(10);

}

for(j = 0; j < 8; j++) {

P1 = codehaledb[j];

delay(10);

}

for(j = 0; j < 8; j++) {

P1 = codehaledc[j];

delay(10);

}

for(j = 0; j < 8; j++) {

P1 = codehaledd[j];

delay(10);

}

for(j = 0; j < 8; j++) {

P1 = codenian[j];

delay(10);

}

for(j = 0; j < 8; j++) {

P1 = codeyue[j];

delay(10);

}

}

}

}

void delay(unsigned int m) {

unsigned int i, j;

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

for(j = 0; j < 123; j++);

}

```

方法二:使用汇编语言编写
