Struct imxrt_hal::gpio::Output

pub struct Output<P> { /* private fields */ }

An output GPIO.

Implementations

impl<P> Output<P>

pub fn set(&self)

Set the GPIO high.

pub fn clear(&self)

Set the GPIO low.

pub fn toggle(&self)

Alternate the GPIO pin output.

toggle is implemented in hardware, so it will be more efficient than implementing in software.

pub fn is_set(&self) -> bool

Returns true if the GPIO is set.

pub fn release(self) -> P

Release the underlying pin object.

pub fn pin(&self) -> &P

Access the underlying pin.

pub fn pin_mut(&mut self) -> &mut P

Mutably access the underling pin.

impl Output<()>

pub fn without_pin<const N: u8>(port: &mut Port<N>, offset: u32) -> Self

Allocate an output GPIO without a pin.

Prefer using Port::output to create a GPIO ouptut with a pin resource. That method ensures that pin resources are managed throughout your program, and that the pin is configured to operate as a GPIO output.

You may use this method to allocate duplicate Output object for the same physical GPIO output. This is considered safe, since the Output API is reentrant.

If you use this constructor, you’re responsible for configuring the IOMUX multiplexer register.
