BBC micro:bit display
#####################

Overview
********
A simple example that demonstrates how to use the 5x5 LED matrix display
on the BBC micro:bit board.

Building
********

This project outputs various things on the BBC micro:bit display. It can
be built as follows:

.. code-block:: console

   $ cd samples/boards/microbit/display
   $ make

Sample Output
=============

The sample app displays a countdown of the characters 9-0, iterates
through all pixels one-by-one, displays a smiley face, some animations,
and finally the text "Hello Zephyr!" by scrolling.
drivers: Add support for BBC micro:bit LED display Adds a simple driver to access the 5x5 LED display found on BBC micro:bit boards. The display is so limited that no effort is done to try to integrate with the existing console (which would likely make the display unusable). Instead, dedicated mb_display_* APIs are added that are specific to this display.

drivers: display: mb_display: Unify image and string APIs Both the string and image rendering may want to take advantage of scrolling and sequential display capabilities. Consolidate the APIs so that there's a single one for images (mb_display_image) and a single one for strings (mb_display_print). Both take a duration parameter for the per-frame duration as well as a mode parameter which specifies sequential vs scrolling behavior as well as an optional looping flag.
