改數組

明顯原理圖與程序不匹配，樓主得提供電路圖才好修改

改為：
uchar code smg_du[]={//共陽數碼管段碼"0~f"
                0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,
                0x80,0x90,0x88,0x83,0xc6,0xa1,0x86,0x8e};  
uchar dis_smg[4];//顯示數字緩存

是共陰的還是共陽的不要搞反

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