Struct Output 

pub struct Output { /* private fields */ }

An output GPIO.

Implementations

impl Output

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 is_pad_high(&self) -> bool

Returns true if the value of the pad is high.

Can differ from is_set(), especially in an open drain config.

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

Allocate an output GPIO without a pin.

Prefer using Port::output to create a GPIO output 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.
