to solder the 5 INT jumper to use it. You will also need to
adjust driver configuration and its Device Tree entry to make use of
it.
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 Shields for more details).
Programming
Set -DSHIELD=buydisplay_2_8_tft_touch_arduino when you invoke
west build. For example:
# From the root of the zephyr repository
west build -b nrf52840dk_nrf52840 samples/subsys/display/lvgl -- -DSHIELD=buydisplay_2_8_tft_touch_arduino
