使用LED点阵滚动显示数字,实现了垂直方向的滚动(代码如下),但是怎么实现水平方向上的滚动呢?
我把行列扫描互换后,水平是水平了,可数字全躺平了 该怎么解决呢?请各位大神帮帮忙吧,先谢了.
单片机源程序如下:
#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
