ds1302的时钟，写好程序后没有报错，也会变化，但显示的时候都是零，我猜测可能是初始化没搞好，但我看了好久找不到错误，希望大神可以帮下我！！！（这是主程序）

Question

include "reg52.h"

include "DS13.h"

typedef unsigned char u8;
typedef unsigned int u16;
sbit LSA=P2^2;
sbit LSB=P2^3;
sbit LSC=P2^4;
u8 DisplayData[8];
u8 code smgduan [10]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f};
void delay (u16 i)
{
while (i--);
}
void datapros ()
{ DS1302ReadTime();
DisplayData[0]=smgduan[TIME[2]/16]; //? ??λ 16???????****1111???????λ?????
DisplayData[1]=smgduan[TIME[2]&0x0f]; //??λ
DisplayData[2]=0x40; //????
DisplayData[3]=smgduan[TIME[1]/16]; //?? ??λ

}
void DigDisplay ()
{
u8 i;
for (i=0;i<8;i++)
{
switch(i)
{
case (0): //???i????0???????????
LSA=0;LSB=0;LSC=0;break; //break????????case (0)?????switch
case (1):

}
P0=DisplayData[i];

P0=0x00; //??????????????
}
}
void main ()
{
DS1302Tnit ();
while (1)
