Question about LVGL + nRF Connect SDK support for e-ink display

[Mohammad Afaneh]

Hi,

Is there any existing support for an e-ink display interfacing with the nRF52840? Something that already has an existing LVGL driver and can be integrated with an nRF Connect SDK application?

Thanks!

Hi,

It should be possible to integrate e-ink display with the nRF52840DK. We have the LVGL sample for the nRF Connect SDK.

Moreover, you can request sample code or driver for this, from E-ink by requesting them.

Regards,

Priyanka

Thanks for pointing me to the example. I will check it out.

Regarding "e-ink", I used this as a generic term similar to "e-paper" (https://en.wikipedia.org/wiki/Electronic_paper) and not referring to the specific EInk brand. Does the Nordic team have any input on any e-paper technology display that's supported by LVGL?

Hello Mohammad,

Zephyr supports a few different e-ink displays from Waveshare, the list (which lists some display part numbers, some display IC part numbers) is available here:

docs.zephyrproject.org/.../index.html
 

There are a few Waveshare offerings from this list. Others are available. For a full list of display ICs supported in Zephyr check here:
