C语言高手来帮帮忙

下面是个电子钟的C语言程序，但如要在P1．5端口加一个发光二极管做秒位的闪动，要怎么改程序。


#include <at89x52.h>
#include <DS1302.h>
unsigned char code dispcode[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,0xbf};
unsigned char time[]={0,0,0,0,0,0,0,0};
unsigned char date[]={0,0,0,0,0,0,0,0};
SYSTEMTIME time1;

void delay(unsigned char i)
{
unsigned char j;
while((i--)!=0)
{
for(j=123;j>0;j--);
}
}
unsigned char button_time(n,x,y)
unsigned char n,x,y;
{
if(P1_7==0)
{
delay(50);
if(P1_7==0)
{
n++;
if(n==x)
n=0;
while(P1_7==0);
}
}
}
unsigned char button_date(n,x,y)
