Trait InputPin

pub trait InputPin {
    type Error;

    // Required methods
    fn is_high(&self) -> Result<bool, Self::Error>;
    fn is_low(&self) -> Result<bool, Self::Error>;
}

Single digital input pin

This trait is available if embedded-hal is built with the "unproven" feature.

Error type

Required Methods

fn is_high(&self) -> Result<bool, Self::Error>

Is the input pin high?

fn is_low(&self) -> Result<bool, Self::Error>
