Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers Now that device_api attribute is unmodified at runtime, as well as all the other attributes, it is possible to switch all device driver instance to be constant. A coccinelle rule is used for this: @r_const_dev_1 disable optional_qualifier @ @@ -struct device * +const struct device * @r_const_dev_2 disable optional_qualifier @ @@ -struct device * const +const struct device * Fixes #27399 Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>		2020-09-02 13:48:13 +02:00

BBC micro:bit pong game
#######################

Overview
********

Play pong over as single player or Bluetooth between two micro:bit
devices.

The game works by controlling a paddle with the two buttons of the
micro:bit (labeled A and B). Initially the playing mode is selected: use
button A to toggle between single- and multi-player, and press button B
to select the current choice. To start the game, the player with the
ball launches the ball by pressing both buttons.

When multi-player mode has been selected the game will try to look for
and connect to a second micro:bit which has also been set into multi-
player mode.

If the board has a piezo buzzer connected to pin 0, this will be used to
generate beeps whenever the ball hits a wall or the paddle.
