[I found out the issue, it's newbee one :) I enabled interrupts early and it ISR is called before I initialized a device, working with that device caused an error. Thanks for the response and the blog!](https://hashnode.com/posts/stm32f4-embedded-rust-at-the-hal-timer-interrupts/630cc3b556df9e8e502523bf/comment/67a0a6c840988f0f9f286ed6#reply-67a0e52f52e680d5e965c3f7)

[Hello, thanks for the article! I'm trying to set a low value for timer it panics, e.g. timer.start(100.millis()).unwrap(); I'm using STM32F103C8T6. Any thoughts on why?](https://hashnode.com/posts/stm32f4-embedded-rust-at-the-hal-timer-interrupts/630cc3b556df9e8e502523bf/comment/67a0a6c840988f0f9f286ed6)
