Required methods

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

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

Implementors

impl<'gpio, T> OutputPin for Pin<T, Gpio<'gpio, Output>> where
    T: PinTrait, 

type Error = Void

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

Set the pin output to HIGH

This method is only available, if two conditions are met:

• The pin is in the GPIO state. Use into_gpio_pin to achieve this.
• The pin direction is set to output. See into_output.

Unless both of these conditions are met, code trying to call this method will not compile.

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

Set the pin output to LOW

This method is only available, if two conditions are met:

• The pin is in the GPIO state. Use into_gpio_pin to achieve this.
• The pin direction is set to output. See into_output.

Unless both of these conditions are met, code trying to call this method will not compile.
