前教大家 各位前辈帮忙看看
#include<reg52.h>#define uchar unsigned char
#define uint unsigned int
uchar code table[]={
0x3f,0x06,0x5b,0x4f,
0x66,0x6d,0x7d,0x07,
0x7f,0x6f,0x77,0x7c,
0x39,0x5e,0x79,0x71};
sbit key=P3^4;
sbit dula=P2^6;
sbit wela=P2^7;
void delay(uint z)//延时函数
{
uint x,y;
for(x=z;x>0;x--)
for(y=110;y>0;y--);
}
void main()
{
while(1)
{
wela=1;
P0=0xfe;
wela=0;
P3=0xff;
if(key==0)
{
delay(10);
if(key==0)
{
dula=1;
P0=table;
dula=0;
}
while(!key);
delay(10);
while(!key);
}
else
{
P0=0xff;
}
}
}
大家好
劳烦大家帮我看下我这程序，谢谢
