Johan Hedberg d2ba7950c5 samples: boards/microbit: Use 250 ticks per second for smooth display
To avoid display flickering, use 250 ticks per second instead of the
default 100.

Johan Hedberg a90735d64c samples: microbit/pong: Disable advertising when connected
The state machine of the game assumes that the user needs to
explicitly re-select multiplayer game when disconnected. We need to
therefore make sure that advertising stays off as soon as the first
connection happens.

Johan Hedberg eb89db26b5 samples: microbit/pong: Fix disabling sound when ending game
Occasionally the sound might stay enabled for the restart timeout (2
seconds) if the ball would hit the wall right before missing the
paddle. Ensure that it's disabled whenever the game ends.

Johan Hedberg 190b0d1a10 samples: microbit/pong: Filter out spurious button presses
The buttons on the microbit cause quite easily "ghost" key presses.
Add a simple filter that ignores button presses from the same button
that happen less than 100ms from each other.

Johan Hedberg 0b16e8ada5 samples: microbit/pong: Increase ISR stack size
The stuff that the GPIO button callback does (in particular the printk
calls) requires more stack space from the ISR stack. Increase it to 1k
from the default 640.

Johan Hedberg 9a7cb7134a samples: microbit/pong: Add initial draft of a pong game
Add initial draft of a pong game using the display on the micro:bit
and its two buttons. This draft only supports a solo game where the
ball bounces from the "roof" and lets the player play against himself.

Johan Hedberg d7a189d2ec 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.

David B. Kinder 0f77021ba7 doc: add labels to board-specific sample docs
Docs need a label at the top so we can use :ref:`labelname`
to create a link to that doc from other docs.

Johan Hedberg 7e5df0cc02 drivers: display: Enhance BBC micro:bit string output capabilities
Add a new mb_display_print() API which takes printf-style parameters
and outputs scrolling text instead of one character at a time. The
existing mb_display_str() API is renamed to mb_display_string() for
consistency, and now also takes printf-style parameters.

Johan Hedberg 380d24de1d 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.
