Provided methods
fn get_bin_data(&mut self) -> AttributeResult<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.
fn get_bin_data_format(&mut self) -> AttributeResult<String>
Returns the format of the values in bin_data
for the current mode. Possible values are:
fn get_decimals(&mut self) -> AttributeResult<isize>
Returns the number of decimal places for the values in the value<N>
attributes of the current mode.
fn get_fw_version(&mut self) -> AttributeResult<String>
Returns the firmware version of the sensor if available. Currently only NXT/I2C sensors support this.
fn get_mode(&mut self) -> AttributeResult<String>
Returns the current mode. See the individual sensor documentation for a description of the modes available for each type of sensor.
fn set_mode(&mut self, mode: String) -> AttributeResult<()>
Sets the sensor to that mode. See the individual sensor documentation for a description of the modes available for each type of sensor.
fn get_modes(&mut self) -> AttributeResult<Vec<String>>
Returns a list of the valid modes for the sensor.
fn get_num_values(&mut self) -> AttributeResult<isize>
Returns the number of value<N>
attributes that will return a valid value for the current mode.
fn get_poll_ms(&mut self) -> AttributeResult<isize>
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.
fn set_poll_ms(&mut self, poll_ms: isize) -> AttributeResult<()>
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.
fn get_units(&mut self) -> AttributeResult<String>
Returns the units of the measured value for the current mode. May return empty string if units are unknown.
fn get_value0(&mut self) -> AttributeResult<isize>
fn get_value1(&mut self) -> AttributeResult<isize>
fn get_value2(&mut self) -> AttributeResult<isize>
fn get_value3(&mut self) -> AttributeResult<isize>
fn get_value4(&mut self) -> AttributeResult<isize>
fn get_value5(&mut self) -> AttributeResult<isize>
fn get_value6(&mut self) -> AttributeResult<isize>
fn get_value7(&mut self) -> AttributeResult<isize>
fn get_text_value(&mut self) -> AttributeResult<String>
Returns a space delimited string representing sensor-specific text values. Returns -EOPNOTSUPP
if a sensor does not support text values.
