Hi,

without changing the way you have started to write your code, here is a qui=
ck fix for you.



void interrupt()=20

{=20

   if(intcon & 0x04)=20

   {=20

 	clear_bit(intcon, 2);=20

 	counter++;=20

 =09

 	if(portb =3D=3D 1)

 	{

 	   if(counter =3D=3D 3906)

	   {

 		portb =3D 0;

 	   }

 	}

 	else

 	{

 	   if(counter =3D=3D 2929)

 	   {

 		portb =3D 1;

 	   }

 	}

        counter =3D 0;

    }=20

 }
