custom systick_handler

[MvdLande]

Hi, first of all, thank you for developing XMC-for-Arduino!

I have a question about the systick interrupt handler. I would like to add a custom task scheduler in systick_handler. Currently I have modified the wiring_time.c file and added the required functionality.

However, I noticed that I cannot redefine systick_handler in my sketch. Is there a way to redefine the systick_handler in a sketch?

Hi MvdLande,

Thanks for the question. In the current code, SysTick_Handler is owned by the platform because it also provide core timing functions such as millis(), delay(), and the internal scheduler. A sketch therefore cannot safely redefine it directly.

Could you share a bit more about your use case:
Why do you need to redefine SysTick_Handler?
What kind of task scheduler are you trying to run there, and what functionality is missing from the current implementation?

That context would help us determine how we can help further. Thanks!

BR,
Linjing
