當我把GND用杜邦線和P3^2連起來時，為什么還在執(zhí)行主程序
只是顯示數(shù)字的間隔變慢了
# include
sbit led=P1^0;
sbit dula=P2^6;
sbit wela=P2^7;
unsigned char t,num;
unsigned char code table[] = {0x3f,0x06,0x5b,0x4f,
0x66,0x6d,0x7d,0x07,
0x7f,0x6f,0x77,0x7c,
0x39,0x5e,0x79,0x71};
void delay(unsigned int z)
{
unsigned int x,y;
for(x=z;x>0;x--)
for(y=100;y>0;y--);
}
void main()
{
EA=1;//開總中斷
EX0=1;
while(1)
{
for(num=0;num<16;num++) //讓數(shù)碼管顯示0到F
{
led="1;
dula=1;
P0=table[num];
dula=0;
wela=1;
P0=0xc0;
wela=0;
delay(200);
}
" }
}
void exter0() interrupt 0
{
led="0;
}"
