|
The Micro Bit (also referred to as BBC Micro Bit, stylized as micro:bit) is an
|
|
|
|
|
|
ARM-based embedded system designed by the BBC for use in computer education in
|
|
|
|
|
|
the UK.
|
|
|
|
|
|
|
|
|
|
|
|
The board is 4 cm × 5 cm and has an ARM Cortex-M4F processor, accelerometer and
|
|
|
|
|
|
magnetometer sensors, Bluetooth and USB connectivity, a display consisting of
|
|
|
|
|
|
25 LEDs, a microphone, two programmable buttons, and can be powered by either
|
|
|
|
|
|
USB or an external battery pack. The device inputs and outputs are through five
|
|
|
|
|
|
ring connectors that are part of the 23-pin edge connector.
|
|
|
|
|
|
|

Flashing
|
|
|
|
|
|
========
|
|
|
|
|
|
|
|
|
|
|
|
Build and flash applications as usual (see :ref:`build_an_application` and
|
|
|
|
|
|
:ref:`application_run` for more details).
|
|
|
|
|

|
|
|
|
Here is an example for the :zephyr:code-sample:`hello_world` application.
|
2020-12-24 23:04:39 -08:00
|
|
|
|
|
|
|
|
|
|
First, run your favorite terminal program to listen for output.
|
|
|
|
|
|
|
|
|
|
|
|
.. code-block:: console
|
|
|
|
|
|
|
|
|
|
|
|
$ minicom -D <tty_device> -b 115200
|
|
|
|
|
|
|
|
|
|
|
|
Replace :code:`<tty_device>` with the port where the micro:bit board
|
|
|
|
|
|
can be found. For example, under Linux, :code:`/dev/ttyACM0`.
|
|
|
|
|
|
|
|
|
|
|
|
Then build and flash the application in the usual way.
