求解答這是模擬圖
這是代碼
#include<reg51.h>
sbit P3_7=P3^7;
unsigned char code table[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f};
unsigned char count;
void delay (unsigned int time){
unsigned int j=0;
for (;time>0;time--)
for (j=0;j<125;j++);
}
void main(void){
count=0;
P0=table[count/10];
P2=table[count% 10];
while(1){
if(P3_7== 0){
delay(10);
if(P3_7==0){
count++;
if(count==100)
count=0;
P0=table[count/10];
P2=table[count% 10];
while(P3_7== 0);
}}}}
