硬件布线的时候，为了让信号少走过孔传输，往往可以跳换一下对应关系，交叉段码的脚序，而再软件层面再去调整。这样布线也美观，PCB质量也高点。

对应段码调整
unsigned char code Led3Char[] = { //数码管显示字符转换表
0xeb,0x88,0xb3,0xba,0xd8,0x7a,0x7b,0xa8,0xfb,0xfa
};
unsigned char code Led3CharD[] = { //数码管显示字符转换表
0xef,0x8c,0xb7,0xbe,0xdc,0x7e,0x7f,0xac,0xff,0xfe
};

unsigned char code Led4Char[] = {
0xfa,0x22,0xb9,0xab,0x63,0xcb,0xdb,0xa2,0xfb,0xeb
};
unsigned char code Led4CharD[] = {
0xfe,0x26,0xbd,0xaf,0x67,0xcf,0xdf,0xa6,0xff,0xef
};
