Expand description

Backends for a framebuffer.

One could use a simple array of [PixelColor], or some more elaborate proxy backends.

Example:

use embedded_graphics::{pixelcolor::Rgb565, prelude::RgbColor};
use embedded_graphics_framebuf::{
    backends::{EndianCorrectedBuffer, EndianCorrection},
    FrameBuf,
};

// A potential backend
let mut data = [Rgb565::BLACK; 12 * 11];
let mut fbuf = FrameBuf::new(&mut data, 12, 11);

// Another potential backend that is owned by the framebuffer
let mut fbuf = FrameBuf::new([Rgb565::BLACK; 12 * 11], 12, 11);

let mut fbuf = FrameBuf::new(
    EndianCorrectedBuffer::new(&mut data, EndianCorrection::ToBigEndian),
    12,
    11,
);

Structs

  • EndianCorrectedBuffer
    A backend for FrameBuf which changes the underlying byte order. This can be useful when using the buffer for DMA with peripherals that have a different endianness than the host.

Enums

  • EndianCorrection
    Enum indicating how the bytes should be converted in the host’s memory.
