Module epd_waveshare::epd2in9

A simple Driver for the Waveshare 2.9“ E-Ink Display via SPI

Example for the 2.9 in E-Ink Display

use embedded_graphics::{
    pixelcolor::BinaryColor::On as Black, prelude::*, primitives::{Line, PrimitiveStyle},
};
use epd_waveshare::{epd2in9::*, prelude::*};

// Setup EPD
let mut epd = Epd2in9::new(&mut spi, cs_pin, busy_in, dc, rst, &mut delay)?;

// Use display graphics from embedded-graphics
let mut display = Display2in9::default();

// Use embedded graphics for drawing a line
let _ = Line::new(Point::new(0, 120), Point::new(0, 295))
    .into_styled(PrimitiveStyle::with_stroke(Black, 1))
    .draw(&mut display);

    // Display updated frame
epd.update_frame(&mut spi, &display.buffer(), &mut delay)?;
epd.display_frame(&mut spi, &mut delay)?;

// Set the EPD to sleep
epd.sleep(&mut spi, &mut delay)?;
