Struct DigitalPin

pub struct DigitalPin<'a> { /* private fields */ }

Provides access to a digital pin, e.g. PD4.

Implementations

impl<'a> DigitalPin<'a>

pub fn set(&mut self, high: bool)

Changes pin’s state to low or high.

pub fn set_low(&mut self)

Changes pin’s state to low.

pub fn set_high(&mut self)

Changes pin’s state to high.

pub fn toggle(&mut self)

Changes pin’s state from low to high or from high to low.

pub fn is_low(&mut self) -> bool

Returns whether pin’s state is low.

pub fn is_high(&mut self) -> bool

Returns whether pin’s state is high.

pub fn assert(&mut self, high: bool)

Asserts that pin’s state is high or low.

pub fn assert_low(&mut self)

Asserts that pin’s state is low.

pub fn assert_high(&mut self)

Asserts that pin’s state is high.

pub fn pulse_in(&mut self) -> AvrDuration

Waits until pin switches state (e.g. from low to high or from high to low).

Returns duration it took for the pin to switch state.

pub fn wait_while_low(&mut self) -> AvrDuration

Waits until pin becomes high; if the pin is already high, exits immediately.

Returns duration it took for the pin to get high.

pub fn wait_while_low_timeout( &mut self, timeout: AvrDuration, ) -> Result<AvrDuration, AvrDuration>

Waits until pin becomes high or timeout is reached; if the pin is already high, exits immediately.

Returns a result containing the amount of time that has passed for the device.

If the timeout was reached before the pin state changed, the duration will be contained in the Err variant, otherwise the Ok variant contains the duration it took for the pin to get high.

pub fn wait_while_high(&mut self) -> AvrDuration

Waits until pin becomes low; if the pin is already low, exits immediately.

Returns duration it took for the pin to get low.

pub fn wait_while_high_timeout( &mut self, timeout: AvrDuration, ) -> Result<AvrDuration, AvrDuration>

Waits until pin becomes low or timeout is reached; if the pin is already low, exits immediately.

Returns a result containing the amount of time that has passed for the device.

If the timeout was reached before the pin state changed, the duration will be contained in the Err variant, otherwise the Ok variant contains the duration it took for the pin to get low.

pub fn name(&self) -> String

Return pin’s name, e.g. PC6.
