[−][src]Trait nrf52811_hal::prelude::_embedded_hal_Pwm
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
)
