Struct rust_rpi_4wd_car::Hids

pub struct Hids { /* fields omitted */ }

Proven easier access to audio, visual, and other forms of human interaction with the robot.

Implementations

impl Hids

pub fn new() -> Rr4cResult<Self>

Constructor

pub fn beep<S: Into<Option<f64>>>(&mut self, secs: S)

Used to sound buzzer.

Arguments

• secs - Optional number of seconds to sound buzzer. Defaults to 0.1 seconds. Internally limited between 0.1 and 10 secs.

pub fn blow<S: Into<Option<f64>>>(&mut self, secs: S)

Turn on the fan motor to blow out flame.

Arguments

• secs - Optional number of seconds to run fan. Defaults to 2 seconds. Internal limits to maximum of 60 seconds.

pub fn key_press(&mut self)

Waits for the KEY button on the robot to be pressed.

Filters out noise/debounce the button press.

pub fn lights<R, G, B>(&mut self, red: R, green: G, blue: B) -> Result where
    R: Into<Option<u8>>,
    G: Into<Option<u8>>,
    B: Into<Option<u8>>, 

Used to set all three color LEDs at the same time.

Arguments

• red - Optional brightness for the red LEDs. See set_red() for more info.
• green - Optional brightness for the green LEDs. See set_green() for more info.
• blue - Optional brightness for the blue LEDs. See set_blue() for more info.

pub fn set_blue<C: Into<Option<u8>>>(&mut self, brightness: C) -> Result

Sets to brightness of the blue LEDs.

Arguments

• brightness - How brightly the LED should be lit. 0-100(%) range with 50% default if None is used.

Examples

use rust_rpi_4wd_car::{Hids, Result};
use std::{thread::sleep, time::Duration};

fn main() -> Result {
    let mut hids = Hids::new()?;
    let pause = Duration::from_millis(50);
    println!("Varying brightness of LEDs");
    for i in (0..100).step_by(10) {
        hids.set_blue(i)?;
        sleep(pause);
    }
    hids.set_blue(0)
}

pub fn set_color<C: Into<u8>>(&mut self, index: C) -> Result

Set the LEDs to show a color from a preset list of primary and secondary colors.

Arguments

• Index - Index of a color from list which can be found in the constant LED_COLORS array.

pub fn set_green<C: Into<Option<u8>>>(&mut self, value: C) -> Result

Sets to brightness of the green LEDs.

Arguments

• brightness - How brightly the LED should be lit. 0-100(%) range with 50% default if None is used.

Examples

use rust_rpi_4wd_car::{Hids, Result};
use std::{thread::sleep, time::Duration};

fn main() -> Result {
    let mut hids = Hids::new()?;
    let pause = Duration::from_millis(50);
    println!("Varying brightness of LEDs");
    for i in (0..100).step_by(10) {
        hids.set_green(i)?;
        sleep(pause);
    }
    hids.set_green(0)
}

pub fn set_red<C: Into<Option<u8>>>(&mut self, value: C) -> Result

Sets to brightness of the red LEDs.

Arguments

• brightness - How brightly the LED should be lit. 0-100(%) range with 50% default if None is used.

Examples

use rust_rpi_4wd_car::{Hids, Result};
use std::{thread::sleep, time::Duration};

fn main() -> Result {
    let mut hids = Hids::new()?;
    let pause = Duration::from_millis(50);
    println!("Varying brightness of LEDs");
    for i in (0..100).step_by(10) {
        hids.set_red(i)?;
        sleep(pause);
    }
    hids.set_red(0)
}

pub fn toggle_fan(&mut self) -> Result

Toggle the fan on/off.

pub fn whistle(&mut self)

A short bleep from the buzzer.
