Getting started with Secure Embedded systems : developing IoT systems for micro:bit and Raspberry Pi Pico using Rust and Tock Build secure and reliable IoT applications for micro:bit and Raspberry Pi Pico by using Rust and Tock. One of the first Operating Systems written in Rust Tock is designed to safely run multiple applications on low power devices enabling you to build a secure foundation for IoT systems. It is an open source OS that has recently gained popularity as companies such as Google[1] explore and integrate it into their products. This book guides you through the steps necessary to customize and integrate Tock into your devices. First youll explore the characteristics of Tock and how to run it on two of the most popular IoT platforms: micro:bit and Raspberry Pi Pico. You’ll also take a look at Rust and how to use it for building secure applications with Tock. The book focuses on the Tock kernel internals and presents the steps necessary to integrate new features. From simple drivers to the more complex asynchronous ones you are provided with a detailed description of the Tock kernel API. Next youll review the Tock applications framework for C. Starting from simple Tock APIs to the more complex Inter Process Communication system this book provides a complete overview of the Tock application ecosystem. By taking a practical approach Getting Started with Secure Embedded Systems provides a starting point for building a secure IoT foundation using the Tock Operating System. You will: Use Rust for embedded systems development Write applications and drivers for Tock Customize the Tock kernel for specific hardware platforms Set a solid base for building secure and reliable IoT applications Use Tock to ensure the security of your microcontrollers and integrate them into your projects Manage products that rely on Tock .
