Struct GpioPin 

pub struct GpioPin { /* private fields */ }

A GpioPin represents a single pin on a gpio device.

This is a lightweight wrapper around the Zephyr gpio_dt_spec structure.

Implementations

impl GpioPin

pub unsafe fn wait_for_high(&mut self) -> impl Future<Output = ()> + use<'_>

Asynchronously wait for a gpio pin to become high.

Safety

Safety of multiple GPIOs depends on the underlying controller.

pub unsafe fn wait_for_low(&mut self) -> impl Future<Output = ()> + use<'_>

Asynchronously wait for a gpio pin to become low.

Safety

Safety of multiple GPIOs depends on the underlying controller.

impl GpioPin

pub unsafe fn raw_new( device: *const device, device_static: &'static GpioStatic, pin: u32, dt_flags: u32, ) -> GpioPin

An unsafe constructor intended for use outside of this crate. Does not guarantee any uniqueness (which isn’t guaranteed or needed by the Gpio device anyway).

pub fn is_ready(&self) -> bool

Verify that the device is ready for use. At a minimum, this means the device has been successfully initialized.

pub fn get_gpio(&self) -> Gpio

Get the underlying Gpio device.

pub fn configure(&mut self, extra_flags: gpio_flags_t)

Configure a single pin.

Safety

Concurrency safety is determined by the underlying driver.

pub fn toggle_pin(&mut self)

Toggle pin level.

Safety

Concurrency safety is determined by the underlying driver.

pub fn set(&mut self, value: bool)

Set the logical level of the pin.

pub fn get(&mut self) -> bool

Read the logical level of the pin.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
