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

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

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

Set ``-DSHIELD=st7789v_tl019fqv01`` when you invoke ``west build``. For example:

.. zephyr-app-commands::
   :zephyr-app: samples/gui/lvgl
   :board: nrf52840dk_nrf52840
   :shield: st7789v_tl019fqv01
   :goals: build
