Detailed Description

Abstract ePaper panel interface, framebuffers, and shared types.

Provides a controller-agnostic abstract base class (idfxx::epaper::panel) that concrete drivers — idfxx::epaper::ssd1680, idfxx::epaper::uc8179, and future siblings — implement, plus the framebuffers (idfxx::epaper::mono_framebuffer, idfxx::epaper::gray4_framebuffer) that hold pixel data in the row-major layouts ePaper controllers consume.

The interface models the ePaper update cycle rather than an immediate-mode display: pixel data is first uploaded to the controller's RAM with idfxx::epaper::panel::write (nothing changes on the glass), then made visible with idfxx::epaper::panel::refresh, which drives the physical ink update and blocks until the controller's BUSY line releases. Panels support full refreshes, faster reduced-quality full refreshes, flicker-free partial refreshes, and 4-level grayscale, subject to each driver's capabilities.

Depends on Core Utilities for error handling and GPIO Component for the BUSY and reset lines.
