Any circuit example of PushButtonLedTest for PPDB?

I have the Propeller Professional Development Board instead of the Propeller Education Kit. And I want to do the example of PushButtonLedTest. How should I begin? How do I connect the wire? Thanks

    The pushbuttons and their resistors and the LEDs and their resistors are already wired up on the PPDB just like the PEK tutorials expect. I don't remember which I/O pins are used in the PushButtonLedTest program, but you'd wire up the PPDB the same way using the same I/O pins as with the PEK tutorial.

    That's why it's called professional.

    If you take a look into the schematics of the PPDB you can see that
    - the pushbuttons are already connected with pull-up-resistors
    - the LEDs are already connected with current-limiting resistors

    So you simply plug a wire - one end of the wire into the female connector from a propeller-IO-pin and the other end of the wire into the female connector of the LED or pushbutton
    That's all.

    best regards
