单片机源程序如下:

#include<REG51.H>
#include<intrins.h>
typedef unsigned int uint16_t;
typedef unsigned char uint8_t;
uint8_t code seg_cc_table [] = {0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x77,0x7c};//0-9
uint8_t code dig_cc_table [] = {0xfe,0xfd,0xfb,0xf7,0xef,0xdf};
uint16_t high = 0;
uint16_t period = 0;
sbit pulse = P3^2;
uint8_t total_num[] = {0,0,0,0,0,0};
void delay_ms(uint16_t xms)
{
uint16_t i = 0;
uint8_t j = 0;
for(i = 0; i < xms; i++)
{
for(j = 0; j < 75; j++)
_nop_();
}
}
void main()
{
uint16_t total =0;
uint16_t i = 1;
P2 = 0x00;
P1 = 0x3f;
TMOD = 0x09;
TH0 = 0;
TL0 = 0;
ET0 = 1;
EA = 1;
while(pulse==1);
TR0=1;
while(pulse==0);
while(pulse==1);
TR0=0;
while(1)
{
high = (uint16_t)TH0*256+TL0;
total = high-1;
total_num[0]= total %10;
total_num[1]= total/10 %10;
total_num[2]= total /100%10;
total_num[3]= total /1000%10;
total_num[4]= total /10000%10;
total_num[5]= total /100000;
for(i=0;i<6;i++)
{
P2 = dig_cc_table[i];
P1 = seg_cc_table[total_num[i]];
delay_ms(1);
P1 = 0x00;
}
}
}
