Twenty experiments in low-level programming

This book describes a series of experiments in programming the BBC micro:bit at a low level.

Chapters will appear one-by-one in coming weeks, starting with some experiments with programming the micro:bit in machine code. If you want to follow along as the book grows, you should get a micro:bit and either a Raspberry Pi or a Linux laptop, and begin with the appendices about hardware and software setup. The hardware setup instructions include some modifications to the micro:bit 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 gmail.com spivoxitygmail.com, or raise issues on the github page if you prefer: http://github.com/Spivoxity/baremetal.
