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 will try but the problem must be somewhere else.

because
even the code above does not work. b14 is not active or passive.

attach main.c 

 

I added.

if (HAL_GetTick() - tick_start >= 500) {

 HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_12); // 

 HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_13);

 HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_14);

 tick_start = HAL_GetTick(); //

 }

even this code is not working.
I think there is a problem with HAL_GetTick();..
HAL_GetTick(); may not be working.

Seems you project isnt configured... HAL_IncTick is in Systick IT handler , but systick isnt configured...

How you manage project ? CubeMX ?

Or timers is misconfigured and ISR took long, then main code never run. Know you how debug code?

Try comment all timers out.

I am using stm32cubeide. If I send you my project file, can you review it? Just find my mistake about the hal_gettick(); function. I control my project with timers. I don't understand which one is longer.

I use test5.rar and main.c , and try send you back working code.

I don't know which file is in test 5, but the solution you make there will still be useful to me.

Try this main file
