Struct InputBuilder

pub struct InputBuilder<P>
where
    P: Peripheral,
    <P as Peripheral>::P: InputPin,
{ /* private fields */ }

Builder type for Input, can be obtained with Input::builder().

Implementations

impl<P> InputBuilder<P>

where P: Peripheral + 'static, <P as Peripheral>::P: InputPin,

pub fn schmitt_trigger(self, enable: bool) -> InputBuilder<P>

Configures the input’s Schmitt trigger.

Note

Fails to compile if the HAL does not support configuring Schmitt trigger on inputs.

impl<P> InputBuilder<P>

where P: Peripheral + 'static, <P as Peripheral>::P: InputPin,

pub fn build(self) -> Input

Returns an Input by finalizing the builder.

pub fn build_with_interrupt(self) -> Result<IntEnabledInput, Error>

Available on crate feature external-interrupts only.

Returns an IntEnabledInput by finalizing the builder.

Errors

On some MCU families, the number of external interrupts that can simultaneously be enabled is limited by the number of hardware interrupt channels. Some MCU families also have other limitations, for instance it may not be possible to register interrupts on a pin if one is already registered on the pin with the same pin number of another port (e.g., PA0 and PB0). In these cases, this returns an Error::InterruptChannel, with a HAL-specific error.
