是消影問(wèn)題，改一下程序就好了

可能是有特殊字符被屏蔽了，代碼最好用代碼框框起來(lái)

可以說(shuō)詳細(xì)一點(diǎn)嗎？我真的想不出辦法來(lái)了

#include<reg52.h>
unsigned char lie[]={0x7f,0xbf,0xdf,0xef,0xf7,0xfb,0xfd,0xfe};
unsigned char hang[3][8]={0x00,0x18,0x24,0x24,0x24,0x24,0x18,0x00, //數(shù)字0 0x00,0x3c,0x20,0x38,0x04,0x24,0x38,0x00, //數(shù)字5 0x00,0x00,0x36,0x49,0x49,0x49,0x36,0x00}; //數(shù)字8
int a,i,j;
void main()
{
TMOD=0x01;
TH0=(65536-50000)/256;
TL0=(65536-50000)%256;
TR0=1;
while(1)
{
P2=hang[j][i];
P1=lie[i];
i++;
if(i==8)
{
i=0;
}
if(TF0==1)
{
TF0=0;
a++;
if(a==10)
{
a=0;
j++;
if(j==3)
{
j=0;
}
}
}
}
}

又來(lái)寫(xiě)一遍，好煩啊。大家可以看一下圖片和程序，按照正常的思路數(shù)字“0”在8*8點(diǎn)陣第一行應(yīng)該是0x00，第二行應(yīng)該是0x18,我按照這種思路用delay函數(shù)寫(xiě)過(guò)一遍結(jié)果是正常的，用定時(shí)器就出現(xiàn)上面這中情況，先謝謝大家了。
