Struct embassy_stm32::gpio::OutputOpenDrain

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

GPIO output open-drain driver.

Note that pins will return to their floating state when OutputOpenDrain is dropped. If pins should retain their state indefinitely, either keep ownership of the OutputOpenDrain, or pass it to core::mem::forget.

Implementations

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

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

Create a new GPIO open drain output driver for a Pin with the provided Level and Speed, Pull configuration.

pub fn degrade(self) -> Output<'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.

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 current pin input level.

pub fn set_high(&mut self)

Set the output as high.

pub fn set_low(&mut self)

Set the output as low.

pub fn set_level(&mut self, level: Level)

Set the output level.

pub fn is_set_high(&self) -> bool

Get whether the output level is set to high.

pub fn is_set_low(&self) -> bool

Get whether the output level is set to low.

pub fn get_output_level(&self) -> Level

Get the current output level.

pub fn toggle(&mut self)

Toggle pin output
