WAVESHARE e-Paper Raw Panel Shield¶
Overview¶
The WAVESHARE e-Paper Raw Panel Shield is a universal driver shield. The shield can be used to drive various Electrophoretic (electronic ink) Display (EPD) with a SPI interface. This shield includes a 23LC1024 1Mb SPI Serial SRAM that is not currently supported by the Zephyr RTOS.
More information about the shield can be found at the Universal e-Paper Raw Panel Driver Shield website 1.

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
