# Interrupt handling
|
|
|
|
We haven't covered interrupt handling in the workshop but the `cortex-m-rt` crate provides attributes to declare exception and interrupt handlers: `#[exception]` and `#[interrupt]`. You can find documentation about these attributes and how to safely share data with interrupt handlers using Mutexes in the ["Concurrency" chapter][concurrency] of the Embedded Rust book.
|
|
|
|
Another way to deal with interrupts is to use a framework like Real-Time Interrupt-driven Concurrency ([RTIC]); this framework has a [book] that explains how you can build reactive applications using interrupts. We use this framework in the advanced level workshop.
