Uefi-graphics2
A blazingly fast embedded-graphics display driver for UEFI environments,
using the embedded-graphics
crate
as its base.
Supports:
- Double buffering
- Display resizing
- An extensive draw/render library using the
embedded-graphics
crate
Why are there 2 other crates for this job?
uefi-graphics
and
uefi-graphics-driver
are 2 crates providing similar purpose,
sadly both seem to either lack functionality or are unmaintained
Example
Here is a simple example with utilising the uefi
crate on version 0.27.0
:
#![no_main]
#![no_std]
extern crate alloc;
use uefi::prelude::*;
use uefi::proto::console::gop::GraphicsOutput;
use uefi_graphics2::embedded_graphics::pixelcolor::{Rgb888, RgbColor};
use uefi_graphics2::UefiDisplay;
#[entry]
fn main(_image_handle: Handle, mut boot_system_table: SystemTable<Boot>) -> Status {
uefi_services::init(&mut boot_system_table).unwrap();
// Disable the watchdog timer
boot_system_table
.boot_services()
.set_watchdog_timer(0, 0x10000, None)
.unwrap();
let boot_services = boot_system_table.boot_services();
let gop_handle = boot_services.get_handle_for_protocol::<GraphicsOutput>().unwrap();
let mut gop = boot_services.open_protocol_exclusive::<GraphicsOutput>(gop_handle).unwrap();
let mode = gop.current_mode_info();
let mut display = UefiDisplay::new(gop.frame_buffer(), mode);
let _ = display.fill_entire(Rgb888::CYAN);
display.flush();
Status::SUCCESS
}
