Before You Start

Make sure your user is a part of video and input group

sudo addusr video richard 
sudo addusr input richard
# Logout and login

To bring up a virtual terminal that isn't being used for X11, you can usually get to it by typing:

ctrl + alt + f2 # or f3,f4...

Sometimes this can only be done from a login screen.

Hello World

use conifer::prelude::*;

fn main() {
    let white = color_from_rgb(255, 255, 255);
    run(move |canvas, event| {
        // if the user swiped, exit
        if let Event::Swipe(s) = event {
            // if the users finger released, exit
            if s.finished {
                return Ok(RunResponse::Exit);
            }
            // draw something where finger is
            for p in s.points {
                canvas.set_pixel(p.x as usize, p.y as usize, white);
            }
        }
        // let conifer know we want to push framebuffer pixels to screen
        Ok(RunResponse::Draw)
    })
    .expect("something went wrong")
}
