Quickstart

use flight_builder::prelude::*;

pub struct SensorReadings {
    pub bar: f32,
    pub temperature: f32,
    pub humidity: f32,
}

pub fn check_sensors(mut readings: ResMut<SensorReadings>) {
    readings.bar = 1.0;
    readings.temperature = 22.0;
    readings.humidity = 0.4;
}

pub fn print_sensors(readings: Res<SensorReadings>) {
    println!(
        "Bar: {}  Temperature: {} Humidity: {}",
        readings.bar, readings.temperature, readings.humidity
    );
}

fn main() {
    let mut s = Scheduler::default();

    // Add sensor reading resource
    s.add_resource(SensorReadings {
        bar: 0.0,
        temperature: 0.0,
        humidity: 0.0,
    });

    // Add a task that updates sensor readings as fast as the system can run
    s.add_task(PerATick, check_sensors);

    // Add a task that runs every 5 seconds
    s.add_task(Update(5.0), print_sensors);

    s.build().run();
}

Flags

• default: By default this crate implments the std flag. To use in no_std, do add the following to your cargo toml instead flight-builder = { version = "0.1.0", default-features = false, features = [<instert platform you are on>] }
• cortex-m: This makes this library work on cortex-m based proccessors. Some examples of cortex-m platforms: RP2040, RP2350, Teensey, and STM32 microcontrollers. Be sure that you have configured your memory.x file accordingly. There are some templates and examples in the examples folder if want to use it. Be sure to set default-features = false.
