This book is designed to help you get started and become comfortable using our tools and ecosystem. Along the way, we’ll introduce the structure of our software stack, and walk through basic workflows using project generation and tooling. By the end, you’ll be ready to explore more advanced material through our reference documentation and external training resources. This book is intended for Rust developers who are interested in embedded development, even if they don’t have prior experience with embedded systems. While some familiarity with low-level programming concepts can be helpful, we aim to introduce key ideas as they come up. If you would like to expand your baseline knowledge, consider studying the additional Resources.

While we strive for stability, users should expect periodic modifications as we improve the API, enhance performance, and introduce new features. Modules that are already stabilized will not be subject to breaking changes, in accordance with semantic versioning - SemVer. However, unstable features—such as parts of the esp-hal and certain drivers are actively being developed and are not covered by SemVer guarantees. This means that using these unstable components may break your project with a simple cargo update, much like working with Rust’s nightly compiler. This kind of instability is common across the broader Rust embedded ecosystem, which is still rapidly evolving. Expect frequent changes and track dependencies closely.

For all major crates, we provide migration guides between releases to help you stay up to date.

Omar Hiari’s “Simplified Embedded Rust” series offers two books, each tailored to different stages of a developer’s Rust and embedded systems journey. The two books, “ESP Core Library Edition” and “ESP Standard Library Edition,” provide comprehensive guidance on using Rust for embedded development on Espressif chips, specifically the ESP32-C3.

The Core Library Edition focuses on a no_std environment, giving developers complete control over their code, ideal for performance-critical applications. The Standard Library Edition, on the other hand, leverages the ESP-IDF framework, making it easier for beginners by providing access to all features supported by ESP-IDF. Overview: The ESP Core Library Edition is designed for developers with some embedded experience. This book uses the no_std environment, offering a lean and efficient approach suitable for performance-critical applications. Expectations: Readers should be aware that this edition is ideal for those who are comfortable with Rust and looking to leverage its performance in a bare-metal environment. The focus on no_std means it’s geared towards developers who need complete control over their code for efficiency and performance.

Overview: The ESP Standard Library Edition is aimed at beginners in embedded systems and Rust developers transitioning to embedded development. This book uses the standard library, making it easier to grasp fundamental concepts without the complexities of a no_std environment. ESP32-C3 is a single-core Wi-Fi and Bluetooth 5 (LE) microcontroller SoC, based on the open-source RISC-V architecture.

Alternatively, real-time chat via IRC is a great way to converse with others, learn new things, and sometimes get answers to questions on the spot. But, having said that, the main drawback to online chat is that not everyone is active or looking at the channel (chat room) at the same moment — people work at different hours and...

So, if you ask a question in the IRC channel, try to stick around, as it might take someone awhile to respond. Development software, tools, environments, languages, platforms, frameworks, libraries, code, and other resources: Erik Bartmann is a seasoned programmer and maker from Germany. He is also a best-selling author who has written many books about programming and electronics. His books are always highly successful across the German-speaking countries in Europe. In November 2016 he published, with Elektror-Verlag, Das ESP8266-Praxisbuch: Mit NodeMCU und ESPlorer (The ESP8266 Practice Book: With NodeMCU and ESPlorer).

In an interview he gave us shortly afterwards, he said he also wanted to write a book about ESP32. And he certainly kept his word! In Das ESP32-Praxisbuch (The ESP32 Practice Book), Erik Bartmann explains readers in a lucid and engaging manner the great variety of projects they can bring to life with Espressif’s flagship System-on-a-Chip. ESP: Hi Erik, the last time we spoke was about your ESP8266 Praxisbuch, which proved to be hugely popular with the international maker community. A little over a year later you released your ESP32 Praxisbuch. Can you please describe the main objective of your new book?

EB: My new book about ESP32 shows that the Wi-Fi module is an integral part of the modern Maker toolbox. I show how to control ESP32 with the Arduino IDE. This tool is known to every maker, so teaching how to work with it is easy. In the book I also show the construction of a hardware development environment, my ESP32 Discovery Board. This board, which every reader can easily build by themselves, makes it possible to carry out many electronics-related projects with ESP32, without having to constantly rebuild breadboards. The didactic benefit is very high.
