Struct InputChannel 

pub struct InputChannel<'d, M: Mode = Blocking> { /* private fields */ }

GPIOTE channel driver in input mode

Implementations

impl<M: Mode> InputChannel<'static, M>

pub fn persist(self)

Persist the channel’s configuration for the rest of the program’s lifetime. This method should be preferred over core::mem::forget() because the 'static bound prevents accidental reuse of the underlying peripheral.

impl<'d> InputChannel<'d, Blocking>

pub fn new<C: Channel, T: GpioPin>( ch: Peri<'d, C>, pin: Peri<'d, T>, pull: Pull, polarity: InputChannelPolarity, ) -> Self

Create a new blocking GPIOTE input channel driver.

The channel’s IN event can be used with PPI through event_in.

impl<'d> InputChannel<'d, Async>

pub fn new_async<C: Channel, T: GpioPin>( ch: Peri<'d, C>, pin: Peri<'d, T>, _irq: impl Binding<C::Interrupt, InterruptHandler<C>> + 'd, pull: Pull, polarity: InputChannelPolarity, ) -> Self

Create a new async GPIOTE input channel driver.

The channel’s GPIOTE interrupt must be bound to InterruptHandler for this channel.

pub fn wait(&mut self) -> impl Future<Output = ()>

Asynchronously wait for an event in this channel.

It is possible to call this function and await the returned future later. If an even occurs in the mean time, the future will immediately report ready.

pub fn wait_for_high(&mut self) -> impl Future<Output = ()>

Asynchronously wait for the pin to become high.

The channel must be configured with InputChannelPolarity::LoToHi or InputChannelPolarity::Toggle. If the channel is not configured to detect rising edges, it is unspecified when the returned future completes.

It is possible to call this function and await the returned future later. If an even occurs in the mean time, the future will immediately report ready.

pub fn wait_for_low(&mut self) -> impl Future<Output = ()>

Asynchronously wait for the pin to become low.

The channel must be configured with InputChannelPolarity::HiToLo or InputChannelPolarity::Toggle. If the channel is not configured to detect falling edges, it is unspecified when the returned future completes.

It is possible to call this function and await the returned future later. If an even occurs in the mean time, the future will immediately report ready.

impl<'d, M: Mode> InputChannel<'d, M>

pub fn pin(&self) -> &Input<'d>

Get the associated input pin.

pub fn event_in(&self) -> Event<'d>

Returns the IN event, for use with PPI.

Trait Implementations

impl<'d, M: Mode> Drop for InputChannel<'d, M>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
