Adafruit 2.8" TFT Touch Shield v2
#################################

Overview
********

The Adafruit 2.8" TFT Touch Shield v2 with a
resolution of 320x240 pixels, is based on the ILI9341 controller.
This shield comes with a resistive (STMPE610 controller)
or capacitive (FT6206 controller) touchscreen. While the
Zephyr RTOS supports display output to these screens,
it currently does not support touchscreen input.
More information about the shield can be found
at the `Adafruit 2.8" TFT Touch Shield v2 website`_.

Requirements
************

This shield can only be used with a board which provides a configuration
for Arduino connectors and defines node aliases for SPI and GPIO interfaces
(see :ref:`shields` for more details).

Programming
***********

Set ``-DSHIELD=adafruit_2_8_tft_touch_v2`` when you invoke ``west build``. For example:

.. zephyr-app-commands::
   :zephyr-app: samples/gui/lvgl
   :board: nrf52840_pca10056
   :shield: adafruit_2_8_tft_touch_v2
   :goals: build
