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

Initializes the I/O driver.

pub fn set_interrupt_priority(&self, prio: Priority)

Sets the interrupt priority and enables GPIO interrupts.

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

Registers an interrupt handler for all GPIO pins.

When using interrupt handlers registered by this method, or by defining a #[no_mangle] unsafe extern "C" fn GPIO() function, the interrupt status register and the interrupt enable setting for the GPIO pin are not cleared automatically. Based on the use case, do one of the following:

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