Reg:Stellaris Launchpad

Hi,

you've missed to include some header files needed.

Add:

#include "inc/hw_types.h"

#include "inc/hw_memmap.h"

#include "driverlib/sysctl.h" 

#include "driverlib/gpio.h"

as basic set.

Have a look at the Stellaris Launchpad Workshop to get you jump-started: http://processors.wiki.ti.com/index.php/Getting_Started_with_the_Stellaris_EK-LM4F120XL_LaunchPad_Workshop
