.. zephyr:code-sample:: draw_touch_events
:name: Draw touch events
:relevant-api: input_events display_interface
Visualize touch events on a display.
Overview
********
This sample will draw a small plus in the last touched coordinates, that way you can check
if the touch screen works for a board, examine its parameters such as inverted/swapped axes.
Building and Running
********************
While this is a generic sample and it should work with any boards with both display controllers
and touch controllers supported by Zephyr (provided the corresponding ``/chosen node`` properties
are set i.e. ``zephyr,touch`` and ``zephyr,display``).
Below is an example on how to build the sample for :zephyr:board:`stm32f746g_disco`:
.. zephyr-app-commands::
:zephyr-app: samples/subsys/input/draw_touch_events
:board: stm32f746g_disco
:goals: build
:compact:
For testing purposes without the need of any hardware, the :ref:`native_sim <native_sim>`
board is also supported and can be built as follows:
.. zephyr-app-commands::
:zephyr-app: samples/subsys/input/draw_touch_events
:board: native_sim
:goals: build
