单片机C语言程序设计：INT0 及 INT1 中断计数

Buffer_Counts[1]=0x0a;

Buffer_Counts[5]=Count_B/100;

Buffer_Counts[4]=Count_B%100/10;

Buffer_Counts[3]=Count_B%10;

if( Buffer_Counts[5]==0)

{

Buffer_Counts[5]=0x0a;

if( Buffer_Counts[4]==0)

Buffer_Counts[4]=0x0a;

}

for(i=0;i6;i++)

{

P2=DSY_Scan_Bits[i];

P1=DSY_CODE[Buffer_Counts[i]];

DelayMS(1);

}

}

//主程序

void main()

{

IE=0x85;

PX0=1;中断优先

IT0=1;

IT1=1;

while(1)

{

if(K3==0) Count_A=0;

if(K4==0) Count_B=0;

Show_Counts();

}

}

//INT0 中断函数

void EX_INT0() interrupt 0

{

Count_A++;

}

//INT1 中断函数

void EX_INT1() interrupt 2

{

Count_B++;

}
