embedded_graphics_framebuffer

lvgl-rs 的帧缓冲区支持

lib.rs:

允许使用LVGL库与帧缓冲区结合。该库将lvgl-rs库和帧缓冲区库连接在一起

连接方式遵循https://docs.rs/embedded-graphics/0.7.1/embedded_graphics/draw_target/trait.DrawTarget.html

示例

要运行示例，请访问https://github.com/rafaelcaricio/lvgl-rs

use embedded_graphics_framebuffer::FrameBufferDisplay;
use std::error::Error;
use embedded_graphics::{
        pixelcolor::{Rgb888, RgbColor},
            prelude::*,
                primitives::{Circle, PrimitiveStyle},
};

fn main() -> Result<(), Box<dyn Error>> {
    let mut display = FrameBufferDisplay::new();
    let circle = Circle::new(Point::new(190, 122), 230)
        .into_styled(PrimitiveStyle::with_stroke(Rgb888::GREEN, 10));
    circle.draw(&mut display)?;
    display.flush().unwrap();
    Ok(())
}
