Setting port as output, turn on led

Start with the documentation & examples included with the kit:

http://www.keil.com/forum/19357/

Hi. I read about GPIO settings.

SysCtlClockSet(SYSCTL_SYSDIV_2,SYSCTL_USE_OSC,SYSCTL_XTAL_16MHZ);
SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOA);
GPIOPinTypeGPIOOutput(GPIO_PORTA_BASE,GPIO_PIN_3);
GPIOPinWrite(GPIO_PORTA_BASE,GPIO_PIN_3,0xff);

I think that the section responsible for set GPIO is correct. I just enable peripheral PORTA, set PIN3 as output and write 1. I think the problem is with SysCtlClockSet. I tried several options with this funkcion and possible set clock wrong. Can anyone explain on example what write to SysCtlClockSet if i wanted to get 6MHz when the external oscillator is 16MHz.

Note that this has nothing to do with Keil - you would be better to ask on the TI Stellaris forum.

If you do cross-post, be sure to provide links between the threads.

But, again, have you tried the examples that TI provide?

They provide a "Blinky" example that does exactly what you're trying to do...

Not familiar with the processor, but you've missed one thing that sure won't help:

#include <LM3Sxxxx.H>
int main()
{
        GPIODirModeSet(GPIO_PORTD_BASE,GPIO_PIN_7,GPIO_DIR_MODE_OUT);
        GPIOPinWrite(GPIO_PORTD_BASE,GPIO_PIN_7,0xff);

        for (;;)  // <<< Make sure you don't fall off the end of 'main' 
          ;
}

I didn't write this but i have the code in while(1) loop so program is running all time. Sorry.

Andrew i saw the Blinky example earlier but it doesn't help me. That example is on another uC and have other APIs functions. I try TI Stellaris forum :)

There is a 'Blinky' example for every Stellaris Evaluation Kit (EK), and the DK-LM3S9B96 - so that covers every Stellaris family!

There is no such thing listed on the TI site - only the DK-LM3S9B96:

focus.ti.com/.../dk-lm3s9b96.html

You didn't - did you?

e2e.ti.com/.../458010.aspx

Maybe they don't have it but i have. On the box is write: Stellaris EKK-LM3S9B96 Evaluation Kit

"There is no such thing listed on the TI site - only the DK-LM3S9B96:"

just because they don't have it now doesn't mean they didn't have it before.

Yes is me. Forgot paste link there. Once again. I really have EKK not DK Evaluation Kit. I have header LM3Sxxxx.H. There is hw_gpio.h and gpio.h documents. They have some APIs that i use in program. But Blinky use functions that aren't declared in my header. Therefore i don't understand when You write that Blinky is for every Evaluation Kit. What i should do? Many thanks for help.

Have you downloaded the complete Stellarisware package?

Have you studied the Stellarisware User Guide?

Did you read the Read Me First document?

Hi. It's working now. One pin from JTAG socket was broken. I solder new one. Thanks for help and Your time.
