Issue

This Content is from Stack Overflow. Question asked by Sina_Torkzadeh

I want to notify my task to run from an ISR. I red the RTOS docs but I could not do it. I would really appreciate if you tell me what I am supposed to do and give an example if it is possible. I used cmsis-V2.
Inside the ISR which I am sure the ISR works correctly I wrote:

if (htim == &htim16)
  {
      BaseType_t xHigherPriorityTaskWoken;
      xHigherPriorityTaskWoken = pdFALSE;
      vTaskNotifyGiveFromISR(ADXL_HandlerHandle , &xHigherPriorityTaskWoken);
      portYIELD_FROM_ISR( xHigherPriorityTaskWoken );
    }

and inside the thask, inside the for loop the first lines are:

ulNotifiedValue = ulTaskNotifyTake( pdFALSE, portMAX_DELAY);
      if( ulNotifiedValue > 0 ){
//my codes ....
}

before for loop I defined:

uint32_t ulNotifiedValue;

but the task is not executed. even once.
I use Nucleo H755ZIQ.

Thanks in advance.
