An Arduino library for driving SPI e-paper (e-ink) displays from Good Display and Waveshare, built on Adafruit_GFX for graphics and text. It supports paged drawing to limit RAM usage as well as full screen buffer and low-level bitmap drawing.
Use cases
- drive an e-paper display from an ESP32 or Arduino
- show text and graphics on a Waveshare e-ink panel
- render images on a Good Display e-paper module with limited RAM
- build a low-power e-ink weather or status display
- update e-paper screens using paged drawing to save memory
When to choose
- you use an Arduino-compatible microcontroller with a supported SPI e-paper panel
- you need Adafruit_GFX-compatible drawing on e-ink hardware
- RAM constraints require paged/picture-loop rendering
When to avoid
- your display uses I2C or parallel interfaces rather than SPI
- you target non-Arduino platforms without the Arduino ecosystem
- you need fast full-color display refresh
