uchar ledtab[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f,0xfc,0xf9,0xf3,0xe7,0xcf,0x9f,0x3f};
void t0isr() interrupt 1
{
TH0=(65536-50000)/256;
TL0=(65536-50000)%256;
times++;
if(times>=40)
{
times=0;
num++;
if(num>14)num=0;
P0=ledtab[num];
}
}
main()
{
TMOD=0x01;
TH0=(65536-50000)/256;
TL0=(65536-50000)%256;
TR0=1;
ET0=1;
EA=1;
P0=ledtab[0];
while(1);
}
