pub struct Input<'d, T: Pin> { /* private fields */ }
Expand description

GPIO input driver.

Implementations§

source§

impl<'d, T: Pin> Input<'d, T>

source

pub fn new(pin: impl Peripheral<P = T> + 'd, pull: Pull) -> Self

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

source

pub fn degrade(self) -> Input<'d, AnyPin>

Type-erase (degrade) this pin into an AnyPin.

This converts pin singletons (PA5, PB6, …), which are all different types, into the same type. It is useful for creating arrays of pins, or avoiding generics.

source

pub fn is_high(&self) -> bool

Get whether the pin input level is high.

source

pub fn is_low(&self) -> bool

Get whether the pin input level is low.

source

pub fn get_level(&self) -> Level

Get the current pin input level.
