Maureen Helm 556da6f99d samples: display: Build NXP boards with adafruit_2_8_tft_touch_v2 shield
Now that we can use the adafruit_2_8_tft_touch_v2 shield with
mimxrt685_evk_cm33 and frdm_k64f boards, start building the display
driver and lvgl samples for these boards in CI.

Display Sample
##############

Overview
********

This sample will draw some basic rectangles onto the display.
The rectangle colors and positions are chosen so that you can check the
orientation of the LCD and correct RGB bit order. The rectangles are drawn
in clockwise order, from top left corner: red, green, blue, grey. The shade of
grey changes from black through to white. If the grey looks too green or red
at any point or the order of the corners is not as described above then the LCD
may be endian swapped.

Building and Running
********************

As this is a generic sample it should work with any display supported by Zephyr.

Below is an example on how to build for a :ref:`nrf52840dk_nrf52840` board with a
:ref:`adafruit_2_8_tft_touch_v2`.

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/display
   :board: nrf52840dk_nrf52840
   :goals: build
   :shield: adafruit_2_8_tft_touch_v2
   :compact:

For testing purpose without the need of any hardware, the :ref:`native_posix`
board is also supported and can be built as follows;

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/display
   :board: native_posix
   :goals: build
