Module epd_waveshare::epd2in13bc

A simple Driver for the Waveshare 2.13“ (B/C) E-Ink Display via SPI More information on this display can be found at the Waveshare Wiki This driver was build and tested for 212x104, 2.13inch E-Ink display HAT for Raspberry Pi, three-color, SPI interface

Example for the 2.13“ E-Ink Display

use embedded_graphics::{prelude::*, primitives::{Line, PrimitiveStyle, PrimitiveStyleBuilder}};
use epd_waveshare::{epd2in13bc::*, prelude::*};

// Setup EPD
let mut epd = Epd2in13bc::new(&mut spi, cs_pin, busy_in, dc, rst, &mut delay)?;

// Use display graphics from embedded-graphics
// This display is for the black/white/chromatic pixels
let mut tricolor_display = Display2in13bc::default();

// Use embedded graphics for drawing a black line
let _ = Line::new(Point::new(0, 120), Point::new(0, 200))
    .into_styled(PrimitiveStyle::with_stroke(TriColor::Black, 1))
    .draw(&mut tricolor_display);

// We use `chromatic` but it will be shown as red/yellow
let _ = Line::new(Point::new(15, 120), Point::new(15, 200))
    .into_styled(PrimitiveStyle::with_stroke(TriColor::Chromatic, 1))
    .draw(&mut tricolor_display);

// Display updated frame
epd.update_color_frame(
    &mut spi,
    &tricolor_display.bw_buffer(),
    &tricolor_display.chromatic_buffer()
)?;
epd.display_frame(&mut spi, &mut delay)?;

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