具體實驗電路圖和實驗程序如下
#include<reg51.h>
sbitKEY0=P1^6; //段選信號的鎖存器控制
sbitKEY1=P1^7; //位選信號的鎖存器控制
unsignedchar code table0[ ]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f};
unsignedchar code table1[ ]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f};
voiddelay(unsigned int i)
{
unsigned int m,n;
for(m=i;m>0;m--)
for(n=90;n>0;n--);
}
voidmain()
{unsigned char num=0;
unsigned char K=0;
P2=0x3F;P3=0x3F;
while(1)

{

if(KEY0==0)
{if(K==9&&num==9)
