使用LED點陣滾動顯示數字,實現了垂直方向的滾動(代碼如下),但是怎么實現水平方向上的滾動呢?
我把行列掃描互換后,水平是水平了,可數字全躺平了 該怎么解決呢?請各位大神幫幫忙吧,先謝了.
單片機源程序如下:
#include <REG51.H>
#define uchar unsigned char //8 0-255
#define uint unsigned int //16 0-65535
void delay(uint xms)
{
uint i,j;
for(i=xms; i>0; i--)
for(j=111; j>0; j--);
}
uchar code table[] = {
0x00,0x00,0x00,0x18,0x24,0x42,0x42,0x42,0x42,0x42,0x42,0x42,0x24,0x18,0x00,0x00, //0
