Trait _embedded_hal_digital_v2_StatefulOutputPin

Source 
pub trait _embedded_hal_digital_v2_StatefulOutputPin: OutputPin {
    // Required methods
    fn is_set_high(&self) -> Result<bool, Self::Error>;
    fn is_set_low(&self) -> Result<bool, Self::Error>;
}
Expand description

Push-pull output pin that can read its output state

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

Required Methods§

Source

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

Is the pin in drive high mode?

NOTE this does not read the electrical state of the pin

Source

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

Is the pin in drive low mode?

NOTE this does not read the electrical state of the pin
