Trait kernel::hil::led::Led

pub trait Led {
    // Required methods
    fn init(&self);
    fn on(&self);
    fn off(&self);
    fn toggle(&self);
    fn read(&self) -> bool;
}

Simple on/off interface for LED pins.

Since GPIO pins are synchronous in Tock the LED interface is synchronous as well.

Required Methods

fn init(&self)

Initialize the LED. Must be called before the LED is used.

fn on(&self)

Turn the LED on.

fn off(&self)

Turn the LED off.

fn toggle(&self)

Toggle the LED.

fn read(&self) -> bool

Return the on/off state of the LED. true if the LED is on, false if it is off.
