epd-datafuri: Adafruit ePaper Display Driver

Supports Adafruit ThinkInk 2.9“ Mono / 4 Grayscale display and Adafruit MagTag 2.9“.

For a complete example see the example.

This driver is loosely modeled after the epd-waveshare drivers.

Architecture

This driver separates hardware control from graphics rendering:

• Driver structs (ThinkInk2in9Mono, MagTag2in9) handle hardware interface and controller commands
• Graphics structs (Display2in9Mono, Display2in9Gray2) handle frame buffers and embedded-graphics integration

This allows multiple graphics buffers (e.g., for grayscale planes) to share a single hardware driver.

Usage

Adafruit ThinkInk 2.9“ Display (Mono/Grayscale, SSD1680)

use epd_datafuri::displays::adafruit_thinkink_290_mfgn::{ThinkInk2in9Mono, Display2in9Mono};

// Create driver and graphics buffer
let mut driver = ThinkInk2in9Mono::new(spi, busy, dc, rst)?;
let mut display = Display2in9Mono::new();

// Draw and update in one command
driver.update_and_display(display.buffer(), &mut delay)?;

For advanced use cases, you can also use the individual update_bw(), update_red(), update(), and update_display() methods for more granular control.
