Covering some of the process rather than the detailed code of porting a python library for a hobbyist eInk display to Elixir. A bit of Nerves, a bit of Scenic, a bunch of refactoring for testability. Guest appearance by the Erlang wxWidgets library. References available for diving into the code. This is more of an overview than a code-along.
