AsyncInput

Struct AsyncInput 

Source
pub struct AsyncInput { /* private fields */ }
Expand description

Async wrapper around a GPIO input pin.

Methods take &'static self because the C-side ove_gpio_irq_register callback retains a pointer to the internal state.

Implementations§

Source§

impl AsyncInput

Source

pub const fn new(pin: GpioPin) -> Self

Wrap a GPIO pin for async edge-event handling.

Source

pub fn arm(&'static self, mode: GpioIrqMode) -> Result<()>

Register the IRQ trampoline and enable interrupts for mode (rising / falling / both). Must be called exactly once.

Source

pub async fn wait_for_event(&'static self)

Await the next edge event. Returns immediately if an edge has fired since the last call to this function.

Source

pub fn is_high(&self) -> Result<bool>

Read the pin’s current logic level.

Source

pub fn pin(&self) -> GpioPin
