改数组

明显原理图与程序不匹配，楼主得提供电路图才好修改

改为：
uchar code smg_du[]={//共阳数码管段码"0~f"
                0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,
                0x80,0x90,0x88,0x83,0xc6,0xa1,0x86,0x8e};  
uchar dis_smg[4];//显示数字缓存

是共阴的还是共阳的不要搞反

uchar code smg_du[]={0x28,0xee,0x32,0xa2,0xe4,0xa1,0x21,0xea,0x20,0xa0,
                       0x60,0x25,0x39,0x26,0x31,0x71,0xff};
把这里改一下
