Struct Chip 

pub struct Chip<T: PwmOps>(/* private fields */);

Wrapper for a PWM chip/controller (struct pwm_chip).

Implementations

impl<T: PwmOps> Chip<T>

pub fn num_channels(&self) -> u32

Gets the number of PWM channels (hardware PWMs) on this chip.

pub fn is_atomic(&self) -> bool

Returns true if the chip supports atomic operations for configuration.

pub fn device(&self) -> &Device

Returns a reference to the embedded struct device abstraction.

pub fn drvdata(&self) -> &T

Gets the typed driver specific data associated with this chip’s embedded device.

pub fn new( parent_dev: &Device, num_channels: u32, data: impl PinInit<T, Error>, ) -> Result<ARef<Self>>

Allocates and wraps a PWM chip using bindings::pwmchip_alloc.

Returns an ARef<Chip> managing the chip’s lifetime via refcounting on its embedded struct device.

Trait Implementations

impl<T: PwmOps> AlwaysRefCounted for Chip<T>

fn inc_ref(&self)

Increments the reference count on the object.

unsafe fn dec_ref(obj: NonNull<Chip<T>>)

Decrements the reference count on the object.
