Expand description

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);
}
