How to light a diode on STM32?

Question

STM

I have an STM32VLD board. For programming I use CooCox 1.7.8.
Googling and sorting through a bunch of examples, I did not understand how to light the idle built-in LED.
Please tell me what am I doing wrong?

#include<stm32f10x_rcc.h>
#include<stm32f10x_gpio.h>
#include "stm32f10x.h"
#include "stm32f10x_conf.h"


GPIO_InitTypeDef GPIO_InitStructure;

volatile int main(void)
{
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC, ENABLE);
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_InitStructure.GPIO_Mode  = GPIO_Mode_Out_PP;
  GPIO_InitStructure.GPIO_Pin   = GPIO_Pin_8 | GPIO_Pin_9;
  GPIO_Init(GPIOC, &GPIO_InitStructure);

  GPIO_WriteBit(GPIOC,GPIO_Pin_9,Bit_SET);
}

Answer 1

In the iar environment, your code works and the LED on C9 lights up.
As for the code - write an infinite loop at the end - while (1) {} - so that the controller does not complete its work

I can assume that at the beginning of creating projects, you did not choose your chip correctly, and the defines that adjust the frequencies depend on this.
