I am trying to work with STM32 board and I want a function, to be executed repeatedly for a certain period of time. The code looks something like this.

while (1)
  {
    /* USER CODE END WHILE */

      for(count = 0; count<1000;count++){
          
          num_display_func(count);
          
         / /HAL_Delay(10);
      }

How to make the function run multiple times, let’s say within in a period of 1 sec?

I have tried using while loop yet I cannot wrap my head around.
