Required Associated Types§

type Error

Error type

Required Methods§

source

fn set_low(&mut self) -> Result<(), Self::Error>

Drives the pin low

NOTE the actual electrical state of the pin may not actually be low, e.g. due to external electrical sources

source

fn set_high(&mut self) -> Result<(), Self::Error>

Drives the pin high

NOTE the actual electrical state of the pin may not actually be high, e.g. due to external electrical sources

Provided Methods§

source

fn set_state(&mut self, state: PinState) -> Result<(), Self::Error>

Drives the pin high or low depending on the provided value

NOTE the actual electrical state of the pin may not actually be high or low, e.g. due to external electrical sources
