Development environment setup

Dealing with microcontrollers involves several tools, as we'll be dealing with an architecture different than your laptop's, and we'll have to run and debug programs on a "remote" device.

Documentation

Without documentation it is pretty much impossible to work with microcontrollers.

We'll be referring to the micro:bit hardware page and the links found within.

HEADS UP Some of the links point to large PDF files several MBs in size.

Tools

We'll use all the tools listed below. Where a minimum version is not specified, any recent version should work but we have listed the version we have tested.

Cargo & rustc.
OpenOCD. version >=0.8
arm-none-eabi toolchain. Tested version: gcc 8.1.0, binutils 2.30.
arm-none-eabi-gdb.
minicom on Linux and macOS. Tested version: 2.7. Readers report that picocom also works but we'll use minicom in this book.
PuTTY on Windows.

Next, follow OS-agnostic installation instructions for a few of the tools:

`rustc` & Cargo

Install rustup by following the instructions at https://rustup.rs.

NOTE Make sure you have a recent version, but only 1.39.0 is validated. rustc -V should return a date newer than the one shown below:

$ rustc -V
rustc 1.39.0 (4560ea788 2019-11-04)

OS specific instructions

Now follow the instructions specific to the OS you are using:
