The mbed pins p27 & p28 are open-drain, so if you're going to use those as outputs,

and wan't them to go high, remember a pull-up resistor.

You cannot pull those high internally. Not even a weak pull-up.

re controlling pins: ..found my answer, here: http://mbed.org/handbook/DigitalIn

The default hello-world program you get when you make a new program already does that. If you want to drive a different pin, replace 'LED1' by one of the other LEDs, or for example p10 for pin 10. (Assuming you have one of the LPC mbeds).

Thanks for this!

of course this assumes that the chip is in FUNC1 and not in Func 2-4, right ?

Every pin can be in a different function. So if you make a pin a DigitalOut, that pin will be set correctly to be a digital out.
