|
|
************
|
||
|
|
|
||
|
|
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_generic`` when you invoke ``west build``. For example:
|
||
|
|
|
||
|
|
.. zephyr-app-commands::
|
||
|
|
:zephyr-app: samples/gui/lvgl
|
||
|
|
:board: nrf52840_pca10056
|
||
|
|
:shield: st7789v_generic
|
||
|
|
:goals: build
