[Microbit-Python] Non volatile storage

[David Whale]

Hi Bruce,

Yes, that will be the problem. The version of MicroPython on the BBC
website is updated on a much slower schedule than the version inside the Mu
editor, and as such, does not have a number of the new features.

Your best bet is to go to codewith.mu and download one of the prebuilt
packages for your platform and use that, as it will have the latest code
(including radio, speech, music, singing and filing system) inside it.

Also Mu has a FILES button that you can use to drag and drop files to and
from the micro:bit file system, and a REPL button that allows you to
interact live with your Python code.

David
