Exchange of data between Papilio Pro and PC

A 3.3V device can drive 5V logic since 3.3V is high enough to be considered a '1' by 5V logic. For the inputs you will need to put a 390 ohm resistor in series to protect the pin from too much current. With the current limiting resistor it is fine to connect a 5V input to the Papilio boards.
