Display Sample
4+
##############
5+
6+
Overview
7+
********
8+
9+
This sample will draw some basic rectangles onto the display.
10+
The rectangle colors and positions are chosen so that you can check the
11+
orientation of the LCD and correct RGB bit order. The rectangles are drawn
12+
in clockwise order, from top left corner: red, green, blue, grey. The shade of
13+
grey changes from black through to white. If the grey looks too green or red
14+
at any point or the order of the corners is not as described above then the LCD
15+
may be endian swapped.
16+
17+
Building and Running
18+
********************
19+
20+
As this is a generic sample it should work with any display supported by Zephyr.
21+
22+
Below is an example on how to build for a :ref:`nrf52840_pca10056` board with a
23+
:ref:`adafruit_2_8_tft_touch_v2`.

25+
.. zephyr-app-commands::
26+
:zephyr-app: samples/drivers/display_shield
27+
:board: nrf52840_pca10056
28+
:goals: build
29+
:shield: adafruit_2_8_tft_touch_v2
30+
:compact:
31+
32+
For testing purpose without the need of any hardware, the :ref:`native_posix`
33+
board is also supported and can be built as follows;
