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 --shield st7735r_ada_160x128 when you invoke west build. For example:
.. zephyr-app-commands:: :zephyr-app: samples/subsys/display/lvgl :board: nrf52840dk/nrf52840 :shield: st7735r_ada_160x128 :goals: build
