Struct embassy_nrf::gpio::Input

pub struct Input<'d> { /* private fields */ }

GPIO input driver.

Implementations

impl<'d> Input<'d>

pub fn new(pin: impl Peripheral<P = impl Pin> + 'd, pull: Pull) -> Self

Create GPIO input driver for a Pin with the provided Pull configuration.

pub fn is_high(&self) -> bool

Get whether the pin input level is high.

pub fn is_low(&self) -> bool

Get whether the pin input level is low.

pub fn get_level(&self) -> Level

Get the pin input level.

impl<'d> Input<'d>

pub async fn wait_for_high(&mut self)

Wait until the pin is high. If it is already high, return immediately.

pub async fn wait_for_low(&mut self)

Wait until the pin is low. If it is already low, return immediately.

pub async fn wait_for_rising_edge(&mut self)

Wait for the pin to undergo a transition from low to high.

pub async fn wait_for_falling_edge(&mut self)

Wait for the pin to undergo a transition from high to low.

pub async fn wait_for_any_edge(&mut self)

Wait for the pin to undergo any transition, i.e low to high OR high to low.
