Question

8*8点阵怎么样才能左右移动？

Answer 1

假如现实以下的字形，对应的数组如 a[8] = {0x01,0x02,0x02,0x03,0x40,0x40};
当实现循环左移时，将a[i+1]的值赋给a[i];将a[0]赋给a[7]；当然说的不大清楚 给你个例子：
#define LEDPORT P1
unsigned char a[8]={0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80};

unsigned char i = 0;
unsigned char j = 0;
unsigned char k = 0;

for(i=0; i<8; i++)
{
for (j=0; j<8; j++)
{
if (j+i >= 8)
{
LEDPORT = a[k++];
}
else
{
LEDPORT = a[j+i];
}
delay();
}
}
