struct  LCD_Data
      {
         unsigned char  RC6:1;
         unsigned char  RC7:1;
         unsigned char  RD4:1;
         unsigned char  RD5:1;
         unsigned char  RD6:1;
         unsigned char  RD7:1;
         unsigned char  RB0:1;
         unsigned char  RB1:1;

      }
这种写法对吗，

1、在h文件中做以下类似定义
#define             UpVal             sysflag.bit0
#define             DownVal             sysflag.bit1
#define             KeySingle          sysflag.bit2
#define             KeyContinue       sysflag.bit3
#define             SetOneClick       sysflag.bit4
#define             UpOneClick          sysflag.bit5
#define             RstOneClick       sysflag.bit6
#define             WriteEeprom       sysflag.bit7

#define             Err_S1             sysflag.bit8
#define             PiCycleTime       sysflag.bit9
#define             WorkLedFlash       sysflag.bit10
#define             OutDelayEnd       sysflag.bit11
#define             PassWordCheckFail sysflag.bit12
#define             FullScreenEnd       sysflag.bit13
typedef             struct             BYTE_BIT
{
uchar             bit0:1;
uchar             bit1:1;
uchar             bit2:1;
uchar             bit3:1;
uchar             bit4:1;
uchar             bit5:1;
uchar             bit6:1;
uchar             bit7:1;
uchar             bit8:1;
uchar             bit9:1;
uchar             bit10:1;
uchar             bit11:1;
uchar             bit12:1;
uchar             bit13:1;
uchar             bit14:1;
uchar             bit15:1;
}BYTEBIT;
2、在C文件中写以下代码：BYTEBIT             sysflag;
3、然后你就可以在C文件中使用KeySingle 等位变量了。
4、以上为我建议的参考写法，请自己仔细阅读
