Problem with Systick Timer STM32F103RB

Posted on February 27, 2015 at 11:12

Hello everybody,

Im working on a project with a nucleo-F103RB with the IDE EM::Blocks and I have some issues with the Systick Timer. I read some relative post but none of them solve my problem.

This is the way i configure the Systick :

void TickTimer_configuration(void)

{

    if(SysTick_Config(SystemCoreClock/1000)) //tick toutes les ms

    {

        // error capture

        GPIO_SetBits(GPIOA,GPIO_Pin_5);

        while(1);

    }

}

I have in another c file, the following function (the header of this filz is include in the main.c file project):

void SysTickHandler(void)

{

    Tick++;

}.

The problem is the next one : when i run my program, the main stop running soon after the SysTick_Config().

I try to debug with other interrupts like EXTI which still work, I also implement an UART to print out the SystemCoreClock value before the SysTick_Config and its at 72MHz.

I ll join in annex the main.c file and the IRQ_handler file. Everything works except the Systick. If you need more informations, just ask.

I hope u can help me.

Sry for my bad english.
