照着网上程序做了一个抢答器 但是 动态显示怎么调整都调整不对

第四位是数字的十位 应该在第一位
第一位是数字的个位 应该在第二位
第二位是显示组别 应该在第四位
程序内部调换 怎么调换 位 都是乱的
除非我把底下接线改了
这是动态显示的程序
void display(uchar number,uchar second) //动态显示
{
uchar second_first,second_second;
second_first = second / 10;
second_second = second % 10;
P2 = 0xfe;
P0 = table[number];
delay(2);
P2 = 0xfd;
P0 = 0xbf;
delay(2);
P2 = 0xfb;
P0 = table[second_first];
delay(2);
P2 = 0xf7;
P0 = table[second_second];
delay(2);
}

支持一下，感谢分享~~~
这个是错的。
动态那个位置怎么都调不对
感觉程序没问题
就是调不对
谁能帮着看看啊
