Delete something!
The simplest way of freeing up space is to delete files from the drive. Perhaps there
are libraries in the lib folder that you aren't using anymore or test code that isn't in
use. Don't delete the lib folder completely, though, just remove what you don't need.
The board ships with the Windows 7 serial driver too! Feel free to delete that if you
don't need it or have already installed it. It's ~12KiB or so.
Use tabs
One unique feature of Python is that the indentation of code matters. Usually the
recommendation is to indent code with four spaces for every indent. In general, that
is recommended too. However, one trick to storing more human-readable code is to
use a single tab character for indentation. This approach uses 1/4 of the space for
indentation and can be significant when you're counting bytes.
On MacOS?
MacOS loves to generate hidden files. Luckily you can disable some of the extra
hidden files that macOS adds by running a few commands to disable search indexing
and create zero byte placeholders. Follow the steps below to maximize the amount of
space available on macOS.
Prevent & Remove MacOS Hidden Files
First find the volume name for your board. With the board plugged in run this
command in a terminal to list all the volumes:
ls -l /Volumes
