[Microbit-Python] Can the micro:bit display text on the Adafruit OLED display?

[Mark Shannon]

Hi Nevil,

The simplest thing to do is to write code that mirrors the micro:bit 
display onto the external display:

def update_external_display():
     for x in range(5):
         for y in range(5)
             external_display.set_pixel(x, y, display.get_pixel(x, y))

Then use the normal display code.

Or, you can get the font data by creating an Image from a character:

 >>> Image("%")
Image('99009:90090:00900:09009:90099:')

Cheers,
Mark.
