Struct Io

pub struct Io { /* private fields */ }

Available on crate feature unstable only.

General Purpose Input/Output driver

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

Implementations

impl Io

pub fn new(_io_mux: IO_MUX) -> Self

Initialize the I/O driver.

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

pub fn set_interrupt_priority(&self, prio: Priority)

Set the interrupt priority for GPIO interrupts.

Panics

Panics if passed interrupt handler is invalid (e.g. has priority None)

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

pub fn set_interrupt_handler(&mut self, handler: InterruptHandler)

Registers an interrupt handler for all GPIO pins.

Note that when using interrupt handlers registered by this function, we clear the interrupt status register for you. This is NOT the case if you register the interrupt handler directly, by defining a #[no_mangle] unsafe extern "C" fn GPIO() function.

Panics

Panics if passed interrupt handler is invalid (e.g. has priority None)

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

Trait Implementations

impl Debug for Io

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

Formats the value using the given formatter.

impl Format for Io

where IO_MUX: Format,

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl InterruptConfigurable for Io

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

fn set_interrupt_handler(&mut self, handler: InterruptHandler)

Registers an interrupt handler for the peripheral.
