GetTick() and HAL_Delay(xxx);

[XooM]

When I give the delay time greater than 300 for the code below (500ms or 1000ms), GetTick or HAL_Delay(500); functions do not work.

If I make the time 100ms, 200ms or 300ms, it works.

When I want to control the delay at longer times, the program does not work.

Where should I look for the problem?
I am using STM32F030C6T6.

	  if(PA10_On==0)
	  {
		  Tick_PA10_On = HAL_GetTick();
		  PA10_On=1;
	  }

	  if ( PA10_On==1 &&(HAL_GetTick() - Tick_PA10_On) >= 300)
	  	 {
		 	 HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_14);
		 	 PA10_On=0;
	  	 }

For example, this code below does not work.

HAL_GPIO_WritePin(PA10_GPIO_Port,PA10_Pin,GPIO_PIN_SET);
HAL_Delay(500);
HAL_GPIO_WritePin(PB14_GPIO_Port,PB14_Pin,GPIO_PIN_RESET);
HAL_Delay(500);

But this below code works.

HAL_GPIO_WritePin(PA10_GPIO_Port,PA10_Pin,GPIO_PIN_SET);
HAL_Delay(200);
HAL_GPIO_WritePin(PB14_GPIO_Port,PB14_Pin,GPIO_PIN_RESET);
HAL_Delay(200);

 Waits of 300ms and below work.

What do you mean by, "do not work"?

• Don't give any delay at all?
• Give an excessive delay?
• Crash?
• Other??

[XooM]

HAL_GPIO_WritePin(PA10_GPIO_Port,PA10_Pin,GPIO_PIN_SET);
HAL_Delay(200);
HAL_GPIO_WritePin(PB14_GPIO_Port,PB14_Pin,GPIO_PIN_RESET);
HAL_Delay(200);

If I write the code above, the PA10 pin goes HIGH and LOW at 200ms intervals.

but the duration is a larger value like 400ms 500ms. It remains in the HIGH position.

Still not clear what is actually happening.

Are you saying that, with a delay value over ~ 400, your code just "stops" at the HAL_Delay() call?

ie, your code becomes equivalent to:

HAL_GPIO_WritePin(PA10_GPIO_Port,PA10_Pin,GPIO_PIN_SET);
while(1);                                                 // Code "sticks" here ?

[XooM]

When I give a value higher than 300ms for the wait time, the output remains in the HIGH position.
I don't know what to do to understand clearly.
I don't know that much.
but I can't control anything with a 500ms delay.
HAL_delay or Gettick both don't work.

Use the debugger:  can you step over that delay, or does it just "stick" in the delay - as if it where a while(1) ... ?

Gettick ... don't work.

Again, what does "don't work" mean here?

What does it do?

Use the debugger to see ...

What is the relation between:

	  if(PA10_On==0)
	  {
		  Tick_PA10_On = HAL_GetTick();
		  PA10_On=1;
	  }

	  if ( PA10_On==1 &&(HAL_GetTick() - Tick_PA10_On) >= 300)
	  	 {
		 	 HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_14);
		 	 PA10_On=0;
	  	 }

and:

HAL_GPIO_WritePin(PA10_GPIO_Port,PA10_Pin,GPIO_PIN_SET);
HAL_Delay(500);
HAL_GPIO_WritePin(PB14_GPIO_Port,PB14_Pin,GPIO_PIN_RESET);
HAL_Delay(500);

?

Need to be concise ..
