RUST EMBEDDED
ENGINEER

Write firmware that runs on bare metal — no OS, no allocator, no excuses.

01

NO_STD FOUNDATIONS

Programming without the standard library. Custom allocators, panic handlers, and linker scripts for microcontroller targets.

book

The Embedded Rust Book

Official guide to embedded development in Rust. Covers toolchain setup, no_std, memory-mapped registers, and HAL abstractions.

book

The Embedonomicon

Deep dive into how embedded Rust programs are structured: linker scripts, startup code, and minimal runtime setup from scratch.

cortex-m-quickstart — project template

Official template for getting a Rust program running on ARM Cortex-M microcontrollers. Start every new embedded project from here.

02

HAL & PERIPHERAL CONTROL

GPIO, UART, SPI, I2C with embedded-hal traits. Writing portable drivers that work across chip families without rewriting.

repo

embedded-hal — hardware abstraction layer

Trait-based HAL that allows writing portable peripheral drivers. If a chip has an embedded-hal impl, your driver just works.

repo

stm32f4xx-hal — STM32 HAL example

Mature HAL implementation for STM32F4 chips. Study the source to understand how embedded-hal traits are implemented.

book

RTIC — Real-Time Interrupt-driven Concurrency

Framework for writing real-time embedded applications. Handles task scheduling, resource sharing, and priority-based interrupt execution.

rtic.rs
03

RTOS & REAL-TIME

Scheduling with RTIC, priority-based interrupt handling, and deterministic latency. Shipping production firmware with Defmt logging.

repo

defmt — deferred formatting for embedded

Ultra-efficient logging framework for embedded Rust. Formats log messages on the host, not the device — minimal overhead.

repo

probe-rs — embedded debugging toolkit

Flash, debug, and log from embedded Rust targets directly from the command line. Replaces OpenOCD + GDB for most workflows.

repo

Embassy — async embedded Rust framework

Modern async framework for embedded Rust. Brings Tokio-style async/await to microcontrollers without an OS.
