菜鸟求助：一个遥控器的程序
我是个菜鸟 想调试个遥控器的程序 弄了一天也没弄出来 希望各位指点一下 我错在哪里我数据接的是p3.2，数码管是共阴的，用两个573和P0口接的#include <reg52.h>
#define uchar unsigned char
#define uint unsigned int
sbit dula=P2^6;
sbit wela=P2^7;
uchar code du[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,
0x7d,0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71};
uchar code we[]={0xfe,0xfd,0xfb,0xf7};
uchar irtime;
uchar startflag;
uchar irdata;
uchar bitnum;
uchar irreceok;
uchar ircode;
uchar disp;
uchar irprosok;
void delayms(uint x)
{
uint i,j;
for(i=x;i>0;i--)
for(j=110;j<0;j--);
}
void display(void)
{
uint i;
for(i=0;i<4;i++)
{
dula=1;
P0=du];
dula=0;
P0=0xff;
wela=1;
P0=we;
wela=0;
delayms(1);
}
}
void timer0init(void)
{
TMOD=0X02;
TH0=0X00;
TL0=0X00;
ET0=1;
EA=1;
TR0=1;
}
void int0init(void)
{
IT0=1;
EX0=1;
EA=1;
}
void irpros()
{
uchar k,i,j;
uchar value;
k=1;
for(j=0;j<4;j++)
{
for(i=0;i<8;i++)
{
if(irdata>6)
{
value=value|0x80;
}
k++;
}
ircode=value;
}
}
void irwork(void)
{
disp=ircode/16;
disp=ircode%16;
disp=ircode/16;
disp=ircode%16;
disp=ircode/16;
disp=ircode%16;
disp=ircode/16;
disp=ircode%16;
}
void main()
{
timer0init();
int0init();
while(1)
{
if(irreceok)
{
irpros();
irreceok=0;
}
if(irprosok)
{
irwork();
irprosok=0;
}
display();
}
}
void timer0() interrupt 1
{
irtime++;
}
void int0()interrupt 0
{
if(startflag)
{
if(irtime>32)
{
bitnum=0;
}
irdata=irtime;
irtime=0;
bitnum++;
if(bitnum==33)
{
bitnum=0;
irreceok;
}
}
else
{
startflag=1;
irtime=0;
}
} 那个显示程序是乱弄的
