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 Shields for more details).
Programming
Correct shield designation (see the table above) for your display must
be entered when you invoke west build.
For example:
# From the root of the zephyr repository
west build -b nrf52840dk_nrf52840 samples/subsys/display/lvgl -- -DSHIELD=waveshare_epaper_gdeh0213b1
