#include"reg51.h"
#include"intrins.h"
typedef unsigned char u8;
typedef unsigned int u16;
  sbit SRCLK=P3^6;
  sbit RCLK=P3^5;
  sbit SER=P3^6;

  u8 ledduan[]={0x10,0x22,0xd4,0x58,0xff,0x58,0x54,0x12};
  u8 ledwei[]={0x7f,0xbf,0xdf,0xef,0xf7,0xfb,0xfd,0xfe};

  void delay(u16 i)
  {
  while(i--);
  }
void Hc595SendByte(u8 dat)
{
u8 a;
SRCLK=0;
RCLK=0;
for(a=0;a<8;a++)
{
SER=dat>>7;
dat<<=1;
SRCLK=1;
_nop_();
_nop_();
SRCLK=0;
}
RCLK=1;
_nop_();
_nop_();
RCLK=0;
}
void main()
{
u8 i;
while(1)
{
P0=0x7f;
for(i=0;i<8;i++)
{
P0=ledwei[i];
Hc595SendByte(ledduan[i]);
delay(100);
Hc595SendByte(0x00);
}
}
}

可否帮我看看问题出在哪
