How to implement the TIM_IRQHandler when using other classes

[Jvan .10]

I'm trying to make a scheduler and everything seems to be ready, now the final step is add the proper function to the IRQ_Handler. This is where my problem starts. At default this uses a extern tim object from the main.c. I removed it there and put it in a class, as required for my project.

from the _it.c file:

void TIM3_IRQHandler(void)
{
  /* USER CODE BEGIN TIM3_IRQn 0 */
 
  /* USER CODE END TIM3_IRQn 0 */
  HAL_TIM_IRQHandler(&htim3);
  /* USER CODE BEGIN TIM3_IRQn 1 */
 
  /* USER CODE END TIM3_IRQn 1 */
}

Now is my question. How can I use the tim located in my scheduler class in the IRQHandler?

Thanks in advance!

IRQ handlers are identified by their names which are defined in g_pfnVectors table of startup code. Hence, TIM3_IRQHandler will only be called on TIM3 events. There is nothing wrong with using htim3 wihin the handler.

Instead of TIM handle struct, keep in the class a pointer to it.

The struct itself will stay global.

(No, one can't really hide a timer in a class instance. If this is not obvious, think on it as a homework).
