Wait but MCU is unblocked

I haven't been able to wait 500ms without affecting the timers for 7 days.
In this block, doesn't PB14 become "0" after 500ms?
Even if I use comment lines, it doesn't work.

Note: volatile uint32_t Counter = 0;
The "Counter" variable is incremented every 1ms with Timer16.

 

** STM32F030C6T6 I'm using.

** Own PCB board..

*** Note: Card of a working system.. There is no card design error.

 

 

if(htim->Instance==TIM16)
		{
		 Counter++;

		if(HAL_GPIO_ReadPin(GPIOC, GPIO_PIN_13)==0)
		  {
			  if(HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_2)==0)
					 {
				         if(PA10_On==0)
				         {
                         HAL_GPIO_WritePin(GPIOB, GPIO_PIN_12,GPIO_PIN_RESET);
                         HAL_GPIO_WritePin(GPIOB, GPIO_PIN_14,GPIO_PIN_SET);
                         Counter=0;
                         PA10_On=1;

                         // Tick_PA10_On= HAL_GetTick();
                         // PA10_On=1;
				         }
				         else
				         {
				          if(Counter>500) // if((HAL_GetTick()-Tick_PA10_On)>=500)
							{
				        	 HAL_GPIO_WritePin(GPIOB, GPIO_PIN_14,GPIO_PIN_RESET);
				        	 Counter=501;
							}
				         }



				   	}
				else
					  {

					  	 HAL_GPIO_WritePin(GPIOB, GPIO_PIN_12,GPIO_PIN_SET);
					  }

		  }
		  else
		  {
			  HAL_GPIO_WritePin(GPIOB, GPIO_PIN_12,GPIO_PIN_RESET);

		  }
}

I give energy to the circuit. I explain what I did in order.

1- I give PC13=0 (No output is active)
2- I give PA2=0, PB14 =1 becomes.. (it waits like that. It is not zero).
So it did not work, sorry.

I added a project made with Stm32CubeIDE that only contains the following codes. Unfortunately, even this code doesn't work. I'm going to go crazy if I can't find where I made a mistake.

  while (1)
  {

	  if(a==0)
	  {
		TickTime=HAL_GetTick();
		a=1;
	  }

	  if(a==1 &&  (HAL_GetTick()-TickTime)>=500)
	  {
		  HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_14);
		  a=0;
	  }
    /* USER CODE END WHILE */

    /* USER CODE BEGIN 3 */
  }
  /* USER CODE END 3 */
}

 

The file is attached and only this code is written, there is no other code but it does not work. 

Know you how debug code ?

I don't know

then switch to it.c and click on line set break point , on left click play button learn use debuger ...

The program is starting to go crazy. This stm32 is going to drive me crazy. I made a mistake by giving up on MicroChip.

HAL_delay command does not work either. Is there a solution for this?

Make sure that SysTick is causing HAL_GetTick() to advance.

If it is not, then HAL_Delay() will not work.

Make sure all the input and output lines are functional.

Need to start from first principles, and confirm what is and what isn't working.

Up vote any posts that you find helpful, it shows what's working..

I have written nothing but a simple blink program.HAL_Delay(500); is not working.I noticed that while I was suspecting that the GetTick(); function was not working.Then when I made a simple Toggle query, it turned out that HAL_Delay() was not working. I don't know how to solve this.

Seems you choice ST versions with some bugy frameworks. I understand your frustration , but try remove systick and use other timebase. Start with open ioc and free TIM16 disable it.

Then choice here

and test your HAL_Delay 500 toggle or my code.
