What do you mean by "external events"?

Using GPIOs as EXTI *interrupt* sources is easy, see examples in the Cube_FW_G0 package. Whether you want to use the "HAL" library for EXTI is another question.

Hi Very interesting. Os there any way to add some level of debaucing to the switch state detection in isr? BR Gilberto Em qua, 29 de mar de 2023 07:49, ST Community escreveu:

Check out this video on how you can use a timercallback to debounce an EXTI
