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 0.28.0:

#![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::helpers::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();
  
  // Get gop
  let gop_handle = boot_services.get_handle_for_protocol::<GraphicsOutput>().unwrap();
  let mut gop = boot_services.open_protocol_exclusive::<GraphicsOutput>(gop_handle).unwrap();
  
  // Create UefiDisplay
  let mode = gop.current_mode_info();
  let mut display = UefiDisplay::new(gop.frame_buffer(), mode);

  // Tint the entire screen cyan
  display.fill_entire(Rgb888::CYAN).unwrap();
  
  // Draw everything
  display.flush();

  // wait 10000000 microseconds (10 seconds)
  boot_services.stall(10_000_000);
  
  Status::SUCCESS
}
