Struct Io

pub struct Io<'d> { /* 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<'d> Io<'d>

pub fn new(_io_mux: IO_MUX<'d>) -> Self

Initialize the I/O driver.

Stability

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)

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, or by defining a #[no_mangle] unsafe extern "C" fn GPIO() function, we do not clear the interrupt status register or the interrupt enable setting for you. Based on your use case, you need to do one of this yourself:

• Disabling the interrupt enable setting for the GPIO pin allows you to handle an event once per call to listen(). Using this method, the is_interrupt_set() method will return true if the interrupt is set even after your handler has finished running.
• Clearing the interrupt status register allows you to handle an event repeatedly after listen() is called. Using this method, is_interrupt_set() will return false after your handler has finished running.

Panics

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