[Microbit-Python] some questions (and where should I ask them normally?)

[Damien George]

Yes, this is the right channel for questions and discussion.

Larry is correct: you construct an image using

img = microbit.Image('0,1,0,0,0\n...')

then use it:

microbit.display.print(img)

To use the greyscale feature you need to first do:

microbit.display.set_display_mode(1)

(Yes that's obscure, it needs a nicer way to do it!)
