E-paper component driver for the ESP-IDF framework and compatible with ESP32 / ESP32S2 can be found in this repository:

Codenamed Cal e-pe-de for the initials of E-Paper Display this is basically all what I’ve been doing the last weeks. Learning more about C++ object oriented coding and preparing a class that can be used to send graphic Buffers to different epaper displays. In order to do that I’m documenting on the go and building at the same time CALE-IDF that is our Firmware version for but this time built on top of the Espressif IoT Development Framework (IDF)

The mission of this new component is to have a similar library for ESP-IDF that is easier to understand. If possible strictly meeting these requirements:

Please find here the Wiki with the models that are already supported in the component:

There are 11 monochrome epapers supported, includeding Good display, and a german brand called PlasticLogic with 4 gray level support. Additionally two other models with colors are supported (5.83 and 7.5 both from Good display, red/black or yellow/black)
