谢谢您了……
您的程序对于我来说相对比较简单、易懂……

用指针 快些

用指针 快些

请大侠赐教用指针快速计算，小弟感激不尽

#define uchar unsigned char
uchar Data_Process (uchar Originle_Data )
{
uchar Data_Temp[4] ;
uchar Data_H_FourBit , Data_L_FourBit ;
uchar i ;
Data_H_FourBit = Originle_Data << 4 ;
Data_L_FourBit = Originle_Data >> 4 ;       
for (i=0 ; i<4 ; i++ )
     {
      Data_Temp[i] = ( Data_H_FourBit >> i )& 0x10 ;  
     }       
for (i=0 ; i<4 ; i++ )
                 {
      Data_H_FourBit |= Data_Temp[i] << ( 7-i )  ;
     }
Originle_Data = Data_H_FourBit | Data_L_FourBit ;
return Originle_Data ;
}

都是高手啊，菜鸟表示深深的折服
