- The [Embedded Rust Book][embedded rust] is a great learning resource, especially the Concurrency chapter.
- If you are looking to write an interrupt handler, look at the [`#[interrupt]` attribute][interrupt]. All interrupts implemented by the nrf52840 hal are listed in [`nrf52840-pac/src/lib.rs`][pac].
It is also recommended that you work through the advanced material of this course to learn about [RTIC][rtic].
