Lpc2000

passing the clock speed in my code should be enough. I don't want to 
re-do thier job! Or they program the chips for me before they ship.

By the way, does anyone know if someone out there is programming LPC 
ships for a fee? Someone ALREADY did it? I contacted ARROW and never 
heard back from them in regards of programing LPC chips!
