EPD Integration

Overview

Use this skill to integrate e-paper displays by proving power sequencing, reset, SPI commands, busy timing, framebuffer layout, waveform/LUT setup, and refresh mode. EPD failures are timing and panel-variant sensitive, so driver code must match the exact module.

When To Use

Use this skill when:

• The user wants to add or debug e-paper/e-ink display panels on MCUs or embedded Linux.
• The issue involves blank screen, stuck busy pin, mirrored image, ghosting, partial refresh artifacts, slow refresh, or high sleep current.
• The project uses SPI, GPIO reset/DC/CS/busy pins, external boost power, partial update, deep sleep, or multiple color planes.

Do not use this skill for generic GUI widget logic. Use lvgl-integration or u8g2-integration after the panel refresh path is proven.
