Source code for use with the book 'Bare Metal micro:bit'.
This copy of the repository has code that suits the newer Version 2 of the BBC micro:bit, based on the Nordic nRF52833 chip. See the other repository for code that runs on the Version 1 board.
Draft material for the book will appear at
https://spivey.oriel.ox.ac.uk/baremetal
The copy of this repository that appears on GitHub is an exact copy of the one that appears at
https://spivey.oriel.ox.ac.uk/git/baremetal-v2.git.
The book is in a rapid phase of evolution at present, and the code and text will not always be in sync -- in particular, code will appear here for testing while the corresponding chapter is still being written.
