When I'm in the Arduino IDE, and I go to Tools->Board, there is no option to select the Arudino "Due". I assume the Arduino Duemilanove and Arduino Due are two different boards, correct? I tried reinstalling the drivers for the Due through Device Manager on Windows 7 and that didn't work. I have the Due plugged into the programming port, as it says in the setup instructions.
So why would the IDE not allow me to select the "Arduino Due" as my board?
