From the Preface

MicroPython is a re implementation of Python 3 for micro controllers and embedded systems. It’s also a staggering feat of engineering to have a reimplemention of Python that works under such constrained circumstances. Why is this important? Micro­Python empowers people: it brings one of the most beautiful, easy-to-learn, and expressive programming languages to the world of embedded development.

This book is intended for anyone who wants to learn how MicroPython is used for embedded development. I expect you to already know Python, but I don’t expect you to be an expert. For example, much of the material found in this book works well in an educational context; so rather than being a professional programmer, you might be a teacher or autodidact.

I aim to give you the understanding, pointers, and ideas you need so you feel confident when working on your own projects.

Most importantly, I want this book to be both fun and inspiring. After reading it, I hope you have enough enthusiasm that you dive in, feet first, to making your own MicroPython-based doohickey, thingamabob, or enchanted object.

This book will provide an overview of the sorts of devices that run MicroPython, prompt you into thinking about how best to develop and execute embedded projects, examine how MicroPython uses and interacts with hardware in order to fulfil various common outcomes and behaviours, and explore idiomatic MicroPython development. It will close with suggestions for next steps.

As with any book, it contains compromises. Some may find it too technical, others not technical enough. Alternatively, some may feel I spend too much time on certain subjects and gloss over others. No matter the compromises I’ve had to make, my intention has been to write something that is easy to read and accessible while providing enough context and signposts to resources for further study. My ultimate aim is simple: to help bring more people to the remarkable technology that is MicroPython.

It’s important to note that MicroPython is a relatively young project. It’s an exciting time to get involved as a community evolves, tools and infrastructure are created, features are added, and bugs are fixed. Given the sharp uptake in conference talks, workshops, and community meetings, there is a lot of enthusiasm in various communities for MicroPython and its nascent potential. Python programmers are learning how to create projects with embedded devices, embedded developers are discovering how much fun it is to use Python, and educators all over the world see MicroPython as a compelling platform for teaching children how to code.

Furthermore, since MicroPython is a re implementation of regular Python, it retains Python’s state as a mature language with an international community of engaged and active programmers.
