KSCAN Interface
####################################
Overview
********
This sample demonstrates how to use the :ref:`KSCAN API <kscan_api>`.
Callbacks are registered that will write to the console indicating KSCAN events.
These events indicate key presses and releases.
Building and Running
********************
The sample can be built and executed on boards supporting a Keyboard Matrix.
Please connect a Keyboard Matrix to exercise the functionality. You need to
obtain the right keymap from the vendor because they vary across different
manufactures.
Sample output
=============
.. code-block:: console
KSCAN test with a Keyboard matrix
Note: You are expected to see several callbacks
as you press and release keys!
