Cale-idf is where we test new versions of CalEPD esp-idf epaper component. Is a repository where CalEPD is working together with our fork of Adafruit GFX.
We started adding some color epapers, already 5.83 and 7.5 inches from Good display are there:

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 CALE.es 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:

• Extendable
• Maintainable
• Object-Oriented Programming with human-readable code and function names
• Easy to add a new Epaper display drivers
• Easy to implement and send stuff to your Epaper displays
• Human-understandable
• Well documented
• ESP-IDF only (No Arduino classes)

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