Trait Implementations§

Source§

impl Polarity for ActiveLow

Source§

const MODE: PolarityMode = PolarityMode::ActiveLow

The corresponding runtime PolarityMode.
Source§

fn physical_on() -> PinState

Physical pin level corresponding to logical ON (GPIO).
Source§

fn physical_off() -> PinState

Physical pin level corresponding to logical OFF (GPIO).
Source§

fn is_logical_on(physical_high: bool) -> bool
