Is digitalwritefast available?

[netkruzer]

I'm trying to turn on my outputs faster than digitalwrite allows. Is there a way to directly talk to PORTD or some other Arduino like command to make it work?

I tried:
PORTD = B10101000;

but Arduino returned this error

'PORTD' was not declared in this scope

   PORTD = B10101000;

edit: I think I figured out my problem. digitalWrite works fast (3.2 microseconds on to off), but delayMicroseconds(1); actually delays 20 microseconds.

Edit again:

void delayCustom(int val){
    for(int i=0;i<val;i++){
        __NOP();
    }     
}

Calling that function will delay about 10us (microseconds) passing in 22.
