I have created a pull request, #612 (https://github.com/espressif/esp-bsp/pull/612). It adds support for non-rectangular epaper displays with at least one dimension larger than 200. 200 is the limit of the SSD1681 controller; larger dimensions use SSD1680 controller.

ESP-BSP contains sample code for a Waveshare 1.54" square eInk display that measures 200x200 bits.
The code can be found at esp-bsp/components/lcd/esp_lcd_ssd1681.
I hope someone who has used this code can help me. I'm trying to adapt it for other Waveshare eInk displays.

SSD1681 is an interface ...

If you upload a project with the "Search for nested projects" field marked, then a bunch of errors about undiscovered libraries appear. And if you download with the "Search for nested projects" unchecked, then everything compiles normally.


Interesting, but not ...

Hello,

Could you replace add_subdirectory(esp_idf/mini_epaper_s3 ) with the set(EXTRA_COMPONENT_DIRS "esp_idf/mini_epaper_s3") see if that helps?

set(EXTRA_COMPONENT_DIRS "esp_idf/mini_epaper_s3")

Project fails to compile, cannot find esp_sleep.h . I am using ESP-IDF v5.4 in VSCode in Windows 11 Pro. I have never had a problem like this with other ESP-IDF projects. I believe this is a problem in c_cpp_properties.json (found in .vscode directory). And I think the problem ultimately arises from ...

Using ESP-IDF extension in VSCode in Windows 10 Pro.

I wanted my project to have two different targets: ESP32c6 with 2.9 inch ePaper and ESP32s3 with 2.7 inch ePaper. So I used ESP-IDF: Open Project Configuration and then select config with ESP-IDF: Select Project Configuration . I was never able ...
