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`_.

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
|
||||
***********
|
||||
|
||||
Correct shield designation (see the table above) for your display must
|
||||
be entered when you invoke ``west build``.
|
||||
For example:
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/gui/lvgl
|
||||
:board: nrf52840_pca10056
|
||||
:shield: waveshare_epaper_gdeh0213b1
|
||||
:goals: build
|
||||
