[ST NUCLEO-U5A5ZJ-Q development board evaluation] 3 Adding timer interrupts [Copy link]

[ST NUCLEO-U5A5ZJ-Q development board evaluation] 3 Adding timer interrupts
Let's use the basic timer first, which is Tim6 and Tim7, so it's easier to understand.
Tim6 Tim7 block diagram is as follows
The time-base unit includes:
Counter Register (TIMx_CNT)
Prescaler Register (TIMx_PSC)
Auto-Reload Register (TIMx_ARR)
Use Stm32cubeide to configure as follows:
1. Select Activated, Prescaler, Counter Mode, Counter Period (AutoReload Register), autoreload preload.
2. Enable interrupts
3. Generate code after saving
4. Add a timer start function to the initialization
5. Write a callback function to handle the timer, which flips a light
6. The light is on. If you want to adjust the flashing interval, you can also add a static variable control in the above callback function as follows:
void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)
{
	if(htim->Instance ==TIM6)// htim6.Instance)
	{
		static uint8_t tim6_ts=2;
		tim6_ts -=1;
		if(0 == tim6_ts)
		{
			HAL_GPIO_TogglePin(LED_RED_GPIO_Port, LED_RED_Pin);
			tim6_ts=2;
		}
	}
}

7. The overall code is as follows:

That’s all I have to report for now. Thank you everyone.
