Posted on February 27, 2015 at 11:12Hello 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.
