Common utility functions for sensors.

Provided Methods§

Source

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

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.

Source

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

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

Source

fn get_decimals(&self) -> Ev3Result<i32>

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

Source

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<()>

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

Source

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

Returns a list of the valid modes for the sensor.

Source

fn get_num_values(&self) -> Ev3Result<i32>

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

Source

fn get_poll_ms(&self) -> Ev3Result<i32>

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 auto detection 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.

Source

fn set_poll_ms(&self, poll_ms: i32) -> Ev3Result<()>

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 auto detection 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.
