將 ˋ主程式段改成: (試看看)
while(1)
{
   for(j=0;j<2;j++)
{
            for(k=0;k<240;k++)
            {
for(i=0;i<8;i++)
                     {
                              dula=1;                //列显示
                              P0=table[j*8+i];
                              dula=0;
                              d_led=1;          //行显示
                              P0=table1[i];
                              d_led=0;
                              delay(200);
                              d_led=1; //清屏
                              P0=0x00;
