Wrap-Up & Next Steps

What You Learned Today

Create → Configure → Control — it works for every peripheral, every HAL, every driver crate.

Step	What You Do	Where in the Docs
Create	Instantiate a driver	Struct page → `new()` or builder
Configure	Set behavior options	Config structs, enums
Control	Read/write/interact	Trait implementations, methods

BSP → Driver Crates → embedded-hal → HAL → PAC → Hardware

You've worked at every level. You know what each layer does and how to read its documentation.

Working example → Read the docs → Adapt → Extend

The example shows ONE way. The docs show ALL ways. Your job is to explore.

Your uFerris board has more peripherals to explore:

Same pattern: find the module in esp-hal docs, Create → Configure → Control.

Embassy is an async runtime for embedded Rust. Instead of interrupt handlers with mutexes, you write async/await code:

#![allow(unused)]
fn main() {
// Instead of interrupt handler + AtomicBool flag:
let level = button.wait_for_falling_edge().await;
led.toggle();
}

Check out embassy.dev and the embassy-executor crate.

The board is yours. Experiment, break things, build projects. The best way to learn is to have a problem you actually want to solve.

Thank you for attending. Now go build something.
