#![no_std]
#![no_main]

use {defmt_rtt as _, panic_probe as _};

use microbit_bsp::*;

use {
    embassy_executor::Spawner,
    embassy_futures::select::{select, Either},
    embassy_time::Duration,
};

#[embassy_executor::main]
async fn main(_spawner: Spawner) {
    let board = Microbit::default();

    let mut display = board.display;
    let mut btn_a = board.btn_a;
    let mut btn_b = board.btn_b;

    display.set_brightness(display::Brightness::MAX);
    display.scroll("Hello, World!").await;
    defmt::info!("Application started, press buttons!");
    loop {
        match select(btn_a.wait_for_low(), btn_b.wait_for_low()).await {
            Either::First(_) => {
                display
                    .display(display::fonts::ARROW_LEFT, Duration::from_secs(1))
                    .await;
            }
            Either::Second(_) => {
                display
                    .display(display::fonts::ARROW_RIGHT, Duration::from_secs(1))
                    .await;
