Trait Implementations

impl<B: Board> GpioPin for Pin<B>

fn read(&self) -> Result<bool>

Reads the value of the GPIO pin.

fn write(&self, value: bool) -> Result<()>

Sets the value of the GPIO pin to value.

fn set_mode(&self, mode: PinMode) -> Result<()>

Sets the mode of the GPIO pin as input, output, or open drain I/O.

fn set_pull_mode(&self, mode: PullMode) -> Result<()>

Sets the weak pull resistors of the GPIO pin.

fn get_internal_pin_name(&self) -> Option<&str>

Not meant for API clients, this method returns the pin name as it is known to the transport (which may have been through one or more alias mappings from the name provided by the API client.) This method is used by implementations of GpioMonitoring.

fn analog_read(&self) -> Result<f32>

Reads the analog value of the GPIO pin in Volts. AnalogInput mode disables digital circuitry for better results, but this method may also work in other modes.

fn analog_write(&self, _volts: f32) -> Result<()>

Sets the analog value of the GPIO pin to value Volts, must be in AnalogOutput mode.

fn set( &self, mode: Option<PinMode>, value: Option<bool>, pull: Option<PullMode>, analog_value: Option<f32>, ) -> Result<()>

Simultaneously sets mode, value, and weak pull, some transports may guarantee atomicity.
