===Twenty experiments in low-level programming===
{{Smallcaps|This book describes}} a series of experiments in programming the BBC {{microbit}} at a low level.
Chapters will appear one-by-one in coming weeks, starting with some experiments with programming the {{microbit}} in machine code.  If you want to follow along as the book grows, you should get a {{microbit}} and either a Raspberry Pi or a Linux laptop, and begin with the appendices about [[Appendix A: Hardware setup|hardware]] and [[Appendix B: Software setup|software]] setup.  The hardware setup instructions include some modifications to the {{microbit}} that will come in handy later, but you don't have to do them before beginning with the first experiment.
Feedback is very welcome, and you can send me e-mail to [mailto:spivoxity@gmail.com <nowiki>spivoxity@gmail.com</nowiki>], or raise issues on the github page if you prefer: https://github.com/Spivoxity/baremetal.

Twenty-one experiments in low-level programming

This is the website for my book, "Bare metal micro:bit", containing online recources to support the book, including updated instructions for setting up the hardware and software you will need, and a page that gathers together documentation on all aspects of the micro:bit hardware.

  • An outline of the book as it will appear.

I am now in discussions with publishers about how to take the project forward, including what will continue to appear on the website. The code for the experiments will remain available on GitHub and continue to be updated. If you would like to look at sample chapters or try out the experiments, please get in touch with me and I will give you access. – Mike
