Struct sysfs_pwm::Pwm

pub struct Pwm { /* fields omitted */ }

Methods

impl Pwm

fn new(chip: u32, number: u32) -> Result<Pwm>

Create a new Pwm wiht the provided chip/number

This function does not export the Pwm pin

fn with_exported<F>(&self, closure: F) -> Result<()> where F: FnOnce() -> Result<()>

Run a closure with the GPIO exported

fn export(&self) -> Result<()>

Export the Pwm for use

fn unexport(&self) -> Result<()>

Unexport the PWM

fn enable(&self, enable: bool) -> Result<()>

Enable/Disable the PWM Signal

fn get_duty_cycle_ns(&self) -> Result<u32>

Get the currently configured duty_cycle in nanoseconds

fn set_duty_cycle_ns(&self, duty_cycle_ns: u32) -> Result<()>

The active time of the PWM signal

Value is in nanoseconds and must be less than the period.

fn get_period_ns(&self) -> Result<u32>

Get the currently configured period in nanoseconds

fn set_period_ns(&self, period_ns: u32) -> Result<()>

The period of the PWM signal in Nanoseconds

Trait Implementations
