Well, you need to give us more of a clue than "things aren't working the way they should" :)
I just tried that code and it partially works, but doesn't work at high speed as I suspected. However, you should see some movement, or noise.
To test the clock and dir outputs, just hook up an LED and resistor. Ideally use a scope.
The schematics show several other inputs, what have you set those to?
What is your board layout?
