Posted on October 16, 2015 at 15:34Hello,
A bit of a beginner question here.
I want to have a timer interrupt to trigger every x mS.
This is the code I've made so far but it's not triggering any interrupt.
int uwPrescalerValue = (uint32_t) ((SystemCoreClock /2) / 10000) - 1;
htim3.Instance = TIM3;
htim3.Init.Prescaler = uwPrescalerValue;
htim3.Init.CounterMode = TIM_COUNTERMODE_UP;
htim3.Init.Period = 100;
htim3.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;
if(HAL_TIM_Base_Init(&htim3) != HAL_OK)
{
while(1)
{
}
}
if(HAL_TIM_Base_Start_IT(&htim3) != HAL_OK)
{
while(1)
{
}
}
__HAL_RCC_TIM3_CLK_ENABLE();
/* Set the TIMx priority */
HAL_NVIC_SetPriority(TIM3_IRQn, 0, 1);
/* Enable the TIMx global Interrupt */
HAL_NVIC_EnableIRQ(TIM3_IRQn);
Am I missing something to enable the timer interrupt here?
Best regards,
Rik
