Trait embedded_hal::Pwm[−][src]

pub trait Pwm {
    type Channel;
    type Time;
    type Duty;
    fn disable(&mut self, channel: Self::Channel);

    fn enable(&mut self, channel: Self::Channel);

    fn get_period(&self) -> Self::Time;

    fn get_duty(&self, channel: Self::Channel) -> Self::Duty;

    fn get_max_duty(&self) -> Self::Duty;

    fn set_duty(&mut self, channel: Self::Channel, duty: Self::Duty);

    fn set_period<P>(&mut self, period: P)
    where
        P: Into<Self::Time>;
}

Pulse Width Modulation

This trait is available if embedded-hal is built with the "unproven" feature.

Examples

Use this interface to control the power output of some actuator

extern crate embedded_hal as hal;

use hal::prelude::*;

fn main() {
    let mut pwm: Pwm1 = {
        // ..
    };

    pwm.set_period(1.khz());

    let max_duty = pwm.get_max_duty();

    // brightest LED
    pwm.set_duty(Channel::_1, max_duty);

    // dimmer LED
    pwm.set_duty(Channel::_2, max_duty / 4);
}

Associated Types

type Channel[src]

Enumeration of channels that can be used with this Pwm interface

If your Pwm interface has no channels you can use the type () here

type Time[src]

A time unit that can be converted into a human time unit (e.g. seconds)

type Duty[src]

Type for the duty methods

The implementer is free to choose a float / percentage representation (e.g. 0.0 .. 1.0) or an integer representation (e.g. 0 .. 65535)
