hi i m new and i don't know much.
i work with a lpcexpresso 1343 and the base board.
the demo programs are working good.
now i want to switch some ports on and off on my own.
do i need all the headers or is it possible to write direct on the registers?
please help

Yes, Like Example:

/* use port0_1 as input event, interrupt test. */
GPIOSetDir( PORT0, 1, 0 );
/* port0_1, single trigger, active high. */
GPIOSetInterrupt( PORT0, 1, 0, 0, 0 );
GPIOIntEnable( PORT0, 1 );

You can write direct.
Or put #defines for don't stay confusion for you.
