include <c8051f350.h>
#include <stdio.h>
#include <intrins.h>
#define uint unsigned int
#define uchar unsigned char
sbit DAT = P1^6;
sbit CLK = P1^5;
uchar code tab[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71};

void sendbyte(uchar byte)
{
   uchar num ,c;
   num=tab[byte];
   for(c=0;c<8;c++)
   {
   CLK=0;
   DAT=num&0x01;
   CLK=1;
   num>>=1;

   }

}

void delay(uint t)
{
  uint x,y;
  for(x=t;x>0;x--)
   for(y=120;y>0;y--);

}

void main()
{
   unsigned char h;
   while(1)
   {
         for(h=0;h<10;h++)
         {
            delay_50ms(1);
            sendbyte(h);
            delay_50ms(10);

         }
         h=0;
   }

}
程序在KEIL里编译时候报错了，P1,DAT,CLK都是unsigned identifier,该怎么解决呢？
