Trait nucleo_f401re::hal::digital::v2::IoPin

pub trait IoPin<TInput, TOutput>where
    TInput: InputPin + IoPin<TInput, TOutput>,
    TOutput: OutputPin + IoPin<TInput, TOutput>,{
    type Error;

    fn into_input_pin(self) -> Result<TInput, Self::Error>;
    fn into_output_pin(self, state: PinState) -> Result<TOutput, Self::Error>;
}

Single pin that can switch from input to output mode, and vice-versa.

Example use (assumes the Error type is the same for the IoPin, InputPin, and OutputPin):

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

Required Associated Types

type Error

Error type.

Required Methods

fn into_input_pin(self) -> Result<TInput, Self::Error>

Tries to convert this pin to input mode.

If the pin is already in input mode, this method should succeed.

fn into_output_pin(self, state: PinState) -> Result<TOutput, Self::Error>

Tries to convert this pin to output mode with the given initial state.

If the pin is already in the requested state, this method should succeed.
