Posted on October 07, 2013 at 08:59hello forum. I am new at arm so first I want to use the GPIO. I use stm3210c-eval. and this development board use stm32f107VC. I write code like this.
#include ''stm32f10x.h''
#include ''stm32_eval.h''
#include <stdio.h>
GPIO_InitTypeDef GPIO_initstructure;
void delay(void)
{
uint8_t i,j;
for(j=0;j<250;j++)
{
for(i=0;i<250;i++);
}
i=0;
j=0;
}
/**
* @brief Main program.
* @param None
* @retval None
*/
int main(void)
{
/* Infinite loop */
while (1)
{
// ilk olarak kullanacagimiz pinlerin bagli oldugu portun clock'unu belirlemeliyiz.
RCC_AHBPeriphClockCmd(RCC_APB2Periph_GPIOD,ENABLE);
// daha sonra port d den hangi pinlerin kullanilacagini , bu pinlerin clock'unu ve mod'unu belirlemeliyiz.
GPIO_initstructure.GPIO_Pin = GPIO_Pin_13 | GPIO_Pin_14 ;
GPIO_initstructure.GPIO_Mode = GPIO_Mode_Out_OD;
GPIO_initstructure.GPIO_Speed = GPIO_Speed_50MHz;
// bu kadar ayarlama pin ayarlarini yapmak için yeterlidir. Simdi biz bu ayarlar1 kaydetmek zorundayiz. Daha sonra program calisacaktir.
GPIO_Init(GPIOD,&GPIO_initstructure);
// böylelikle pin ayarlamasi bitti . simdi bu pinlerle ne yapacagimizi bulmaliyiz.
while(1)
{
GPIO_SetBits(GPIOD,GPIO_Pin_13);
GPIO_SetBits(GPIOD,GPIO_Pin_14);
delay();
GPIO_ResetBits(GPIOD,GPIO_Pin_13);
GPIO_ResetBits(GPIOD,GPIO_Pin_14);
delay();
}
}
}
#ifdef USE_FULL_ASSERT
/**
* @brief Reports the name of the source file and the source line number
* where the assert_param error has occurred.
* @param file: pointer to the source file name
* @param line: assert_param error line source number
* @retval None
*/
void assert_failed(uint8_t* file, uint32_t line)
{
/* User can add his own implementation to report the file name and line number,
ex: printf(''Wrong parameters value: file %s on line %d\r\n'', file, line) */
/* Infinite loop */
while (1)
{
}
}
#endif
But when I load the code to the board , nothing happens. So I debugged the code but in debug , program not exist below code part. How can I solve this problem ?
do
{
HSEStatus = RCC->CR & RCC_CR_HSERDY;
StartUpCounter++;
} while((HSEStatus == 0) && (StartUpCounter != HSE_STARTUP_TIMEOUT));
