Struct Input 

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

GPIO input driver.

Implementations

impl<'d> Input<'d>

pub fn new(pin: Peri<'d, impl Pin>, pull: Pull) -> Self

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

pub const fn from_flex(pin: Flex<'d>) -> Self

Create a GPIO input driver from an existing Flex pin.

This is useful when a pin was previously used in bidirectional mode and needs to be converted to a typed input driver without re-acquiring the peripheral token. The pin should already be configured as an input via Flex::set_as_input().

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 level(&self) -> Level

Get the current pin input level.

pub fn persist(self)

Give up the pin, leaving it configured.

Dropping disconnects the pin, this doesn’t. The pin keeps its configuration after the borrow it came from ends.
