Implementations§

Source§

impl IrSeekerSensor

Source

pub const MODE_AC: &'static str = "AC"

Sensor mode alternating current -> filters the infrared signal of the hitechnic ball -> only shows direction

fn get_fw_version(&self) -> Ev3Result<String>

Returns the firmware version of the sensor if available. Currently only NXT/I2C sensors support this.
Source§

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

Returns the current mode. See the individual sensor documentation for a description of the modes available for each type of sensor.
Source§

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