Lego ports

Implementations

impl LegoPort

pub fn get<T: Port>(port: T) -> Ev3Result<Self>

Try to get a Self on the given port. Returns None if port is not used or another device is connected. Get the port device for this port

Examples

use ev3dev_lang_rust::{Ev3Result, LegoPort};
use ev3dev_lang_rust::sensors::{ColorSensor, SensorPort};
use std::thread;
use std::time::Duration;

fn init_color_sensor(port: SensorPort) -> Ev3Result<ColorSensor> {
    let lego_port = LegoPort::get(port)?;
    lego_port.set_mode("ev3-uart")?;
    lego_port.set_device("lego-ev3-color")?;

    thread::sleep(Duration::from_millis(100));

    ColorSensor::get(port)
}

let color_sensor = init_color_sensor(SensorPort::In1)?;

pub fn find() -> Ev3Result<Self>

Try to find a Self. Only returns a device if their is exactly one connected, Error::NotFound otherwise.

pub fn list() -> Ev3Result<Vec<Self>>

Extract list of connected ‘Self’

pub fn get_address(&self) -> Ev3Result<String>

Returns the name of the port that the device is connected to.

pub fn get_driver_name(&self) -> Ev3Result<String>

Returns the name of the driver that provides this device.

pub fn get_mode(&self) -> Ev3Result<String>

Returns the currently selected mode.

pub fn set_mode(&self, mode: &str) -> Ev3Result<()>

Sets the currently selected mode. Generally speaking when the mode changes any sensor or motor devices associated with the port will be removed new ones loaded, however this this will depend on the individual driver implementing this class.

pub fn get_modes(&self) -> Ev3Result<Vec<String>>

Returns a list of the available modes of the port.

pub fn set_device(&self, mode: &str) -> Ev3Result<()>

For modes that support it, writing the name of a driver will cause a new device to be registered for that driver and attached to this port. For example, since NXT/Analog sensors cannot be auto-detected, you must use this attribute to load the correct driver. Returns -EOPNOTSUPP if setting a device is not supported.

pub fn get_status(&self) -> Ev3Result<String>

In most cases, reading status will return the same value as mode. In cases where there is an auto mode additional values may be returned, such as no-device or error. See individual port driver documentation for the full list of possible values.
