单片机6位数码管计数器程序问题

Question

自己写了个51单片机0-999999计数器程序，基于STC12C5A60S2，用75HC573驱动数码管，程序问题为最后一位刷新速度很快，我想要它一秒计数一次，大家帮忙看下程序怎么改？
#include <reg52.H> //STC头文件
#define uchar unsigned char
#define uint unsigned int
#define timewe 3

sbit we = P2^7;
sbit du = P2^6;

uint temp,shiwan,wan,qian,bai,shi,ge;

uchar code duan[]={0x3F,0x06,0x5B,0x4F,0x66,0x6D,0x7D,0x07,0x7F,0x6F};
uchar code wei[]={0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80};

void delay (uint a) // 1ms延时程序（12MHz 10倍于51单片机速度时）
{
uint i;
while( --a != 0)
{
for(i = 0; i < 600; i++);
}
}

void display()
{
temp = 0;
while(1)
{
if(temp == 999999)
temp = 0;

shiwan = temp/100000;
wan = temp%100000/10000;
qian = temp%10000/1000;
bai = temp%1000/100;
shi = temp%100/10;
ge = temp%10;

du = 1;
P0 = duan[shiwan];
du = 0;
we = 1;
P0 = 0xfe;
we = 0;
delay(timewe);

du = 1;
P0 = duan[wan];
du = 0;
we = 1;

delay(5);

temp++;

}追问

这个编译不通过啊。

仿真实例
这个可以参考一下，可以用按键 输入所需 显示 的数字。
