[−][src]Struct ev3dev_lang_rust::sensors::ColorSensor

pub struct ColorSensor { /* fields omitted */ }

LEGO EV3 color sensor.

Methods

`impl ColorSensor`[src]

`pub fn get(port: SensorPort) -> Ev3Result<Self>`[src]

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

`pub fn find() -> Ev3Result<Self>`[src]

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

`pub fn list() -> Ev3Result<Vec<Self>>`[src]

Extract list of connected 'Self'

`pub const MODE_COL_REFLECT: &'static str`[src]

Reflected light - sets LED color to red

`pub const MODE_COL_AMBIENT: &'static str`[src]

Ambient light - sets LED color to blue (dimly lit)

`pub const MODE_COL_COLOR: &'static str`[src]

Color - sets LED color to white (all LEDs rapidly cycling)

`pub const MODE_REF_RAW: &'static str`[src]

Raw Reflected - sets LED color to red

`pub const MODE_RGB_RAW: &'static str`[src]

Raw Color Components - sets LED color to white (all LEDs rapidly cycling)

`pub const MODE_COL_CAL: &'static str`[src]

Calibration ??? - sets LED color to red, flashing every 4 seconds, then goes continuous

`pub fn get_bin_data(&self) -> Ev3Result<String>`[src]

Reading the file will give the unscaled raw values in the value<N> attributes. Use bin_data_format, num_values and the individual sensor documentation to determine how to interpret the data.

`pub fn get_bin_data_format(&self) -> Ev3Result<String>`[src]

Returns the format of the values in bin_data for the current mode. Possible values are:

`pub fn get_decimals(&self) -> Ev3Result<i32>`[src]

Returns the number of decimal places for the values in the value<N> attributes of the current mode.

`pub fn get_fw_version(&self) -> Ev3Result<String>`[src]

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

`pub fn get_mode(&self) -> Ev3Result<String>`[src]

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

`pub fn set_mode(&self, mode: &str) -> Ev3Result<()>`[src]

Sets the sensor to that mode. See the individual sensor documentation for a description of the modes available for each type of sensor.

`pub fn get_modes(&self) -> Ev3Result<Vec<String>>`[src]

Returns a list of the valid modes for the sensor.

`pub fn get_num_values(&self) -> Ev3Result<i32>`[src]

Returns the number of value<N> attributes that will return a valid value for the current mode.

`pub fn get_poll_ms(&self) -> Ev3Result<i32>`[src]

Returns the polling period of the sensor in milliseconds. Returns -EOPNOTSUPP if changing polling is not supported. Note: Setting poll_ms too high can cause the input port autodetection to fail. If this happens, use the mode attribute of the port to force the port to nxt-i2c mode. Values must not be negative.

`pub fn set_poll_ms(&self, poll_ms: i32) -> Ev3Result<()>`[src]

Sets the polling period of the sensor in milliseconds. Setting to 0 disables polling. Note: Setting poll_ms too high can cause the input port autodetection to fail. If this happens, use the mode attribute of the port to force the port to nxt-i2c mode. Values must not be negative.
