Im a newbe to arm family

Im using coocox ide.

I create my 1st project compile n and downloaded to STM32F030-Discovery board.

The project compiled successfully and downloaded but nothing is happening on the board.

What Iam Trying is Just To Turn On The LED.

Below Is My Code Pls Guide Me What Iam Missing.

&sharpinclude <stm32f0xx_gpio.h>

&sharpinclude <stm32f0xx_rcc.h>

GPIO_InitTypeDef Gp; //Create GPIO struct

//Define LED pins

&sharpdefine GreenLED_Pin GPIO_Pin_9

&sharpdefine BlueLED_Pin GPIO_Pin_8

&sharpdefine LED_GPIO GPIOC

int main(void)

{

RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOC, ENABLE);

Gp.GPIO_Pin = GreenLED_Pin; //My alteration

Gp.GPIO_Mode = GPIO_Mode_OUT; //Set GPIO pins as output

Gp.GPIO_OType = GPIO_OType_PP; //Ensure output is push-pull vs open drain

Gp.GPIO_PuPd = GPIO_PuPd_NOPULL; //No internal pullup resistors required

Gp.GPIO_Speed = GPIO_Speed_Level_1; //Set GPIO speed to lowest

GPIO_Init(LED_GPIO, &Gp); //Assign struct to LED_GPIO

    while(1)

    {

     GPIO_SetBits(LED_GPIO, GreenLED_Pin);

    }

}

Thank you

Seems reasonable enough, so load it with the debugger, and step through it.

use keil it is free for stm32f0 devices

http://www2.keil.com/stmicroelectronics-stm32/mdk

and this way you benefit stm32cubemx auto code generation feature

I got this error on keil ide while compiling

what is this  Error: L6320W about ?

Uncheck the 

Use MicroLIB

 checkbox in 

Options for Target

, 

Target

 tab, then rebuild your project.

Seems more probable that the project doesn't contain a startup_stm32f0xx.s file with the vectors and startup code.

You should review the structure of the example/template projects provided with the firmware libraries.

@aslan.mehmet

Use Microlib Is NotChecked.

@Clive1

Actually The Error I Posted Is Shown When I Compile  An Example Project.

I Manually Included Directories In Options->Target -> C/C++ Tab (Keil)
