Common utility functions for sensors.

Provided methods

`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.

`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:

`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.

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

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

`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.

`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.

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

Returns a list of the valid modes for the sensor.

`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.

`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.

`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.
