Create a precision timer with HAL and interrupt

Posted on November 20, 2015 at 12:41

Hi guys,

I'm using CubeMx with HAL STM32F051.

I need to activate a one shot timer with interrupt.

Something likr this:

void StartTimer(unsigned short microSecond){

...

...

}

volatile unsigned char TimerIsOver = 0;

 void HAL_TIM_OC_DelayElapsedCallback(TIM_HandleTypeDef *htim) {

TimerIsOver = 1;

}

void main(void) {

LedOff();

TimerIsOver = 0;

StartTimer(20);

while(!TimerIsOver);

LedOn();

TimerIsOver = 0;

HAL_Delay(50);

LedOff();

StartTimer(340);

while(!TimerIsOver);

LedOn();

}
