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
