API¶

To allow non-blocking usage, nearly every function of the Rust bindings returns a wrapper around a mpsc::Receiver. To block until the function has finished and get your result, call one of the receiver's recv variants. Those return either the result sent by the device, or any error occurred.

Functions returning a result directly will block until the device has finished processing the request.

All functions listed below are thread-safe, those which return a receiver are lock-free.

Basic Functions¶

pub fn BarometerBricklet::new(uid: &str, ip_connection: &IpConnection) → BarometerBricklet¶

Parameters:	uid – Type: &str ip_connection – Type: &IPConnection
Returns:	barometer – Type: BarometerBricklet

Creates a new BarometerBricklet object with the unique device ID uid and adds it to the IPConnection ip_connection:

let barometer = BarometerBricklet::new("YOUR_DEVICE_UID", &ip_connection);

This device object can be used after the IP connection has been connected.

pub fn BarometerBricklet::get_air_pressure(&self) → ConvertingReceiver<i32>¶

Returns:	air_pressure – Type: i32, Unit: 1/1000 hPa, Range: [10000 to 1200000]

Returns the air pressure of the air pressure sensor.

If you want to get the air pressure periodically, it is recommended to use the BarometerBricklet::get_air_pressure_callback_receiver callback and set the period with BarometerBricklet::set_air_pressure_callback_period.

pub fn BarometerBricklet::get_altitude(&self) → ConvertingReceiver<i32>¶

Returns:	altitude – Type: i32, Unit: 1 cm, Range: [-2³¹ to 2³¹ - 1]

Returns the relative altitude of the air pressure sensor. The value is calculated based on the difference between the current air pressure and the reference air pressure that can be set with BarometerBricklet::set_reference_air_pressure.

If you want to get the altitude periodically, it is recommended to use the BarometerBricklet::get_altitude_callback_receiver callback and set the period with BarometerBricklet::set_altitude_callback_period.

pub fn BarometerBricklet::set_reference_air_pressure(&self, air_pressure: i32) → ConvertingReceiver<()>¶

Parameters:	air_pressure – Type: i32, Unit: 1/1000 hPa, Range: [0, 10000 to 1200000], Default: 1013250

Sets the reference air pressure for the altitude calculation. Setting the reference to the current air pressure results in a calculated altitude of 0cm. Passing 0 is a shortcut for passing the current air pressure as reference.

Well known reference values are the Q codes QNH and QFE used in aviation.

pub fn BarometerBricklet::get_reference_air_pressure(&self) → ConvertingReceiver<i32>¶

Returns:	air_pressure – Type: i32, Unit: 1/1000 hPa, Range: [10000 to 1200000], Default: 1013250

Returns the reference air pressure as set by BarometerBricklet::set_reference_air_pressure.

Advanced Functions¶

pub fn BarometerBricklet::get_chip_temperature(&self) → ConvertingReceiver<i16>¶

Returns:	temperature – Type: i16, Unit: 1/100 °C, Range: [-4000 to 8500]

Returns the temperature of the air pressure sensor.

This temperature is used internally for temperature compensation of the air pressure measurement. It is not as accurate as the temperature measured by the Temperature Bricklet or the Temperature IR Bricklet.

pub fn BarometerBricklet::set_averaging(&self, moving_average_pressure: u8, average_pressure: u8, average_temperature: u8) → ConvertingReceiver<()>¶

Parameters:	moving_average_pressure – Type: u8, Range: [0 to 25], Default: 25 average_pressure – Type: u8, Range: [0 to 10], Default: 10 average_temperature – Type: u8, Range: [0 to 255], Default: 10

Sets the different averaging parameters. It is possible to set the length of a normal averaging for the temperature and pressure, as well as an additional length of a moving average for the pressure. The moving average is calculated from the normal averages. There is no moving average for the temperature.

Setting the all three parameters to 0 will turn the averaging completely off. If the averaging is off, there is lots of noise on the data, but the data is without delay. Thus we recommend to turn the averaging off if the Barometer Bricklet data is to be used for sensor fusion with other sensors.

New in version 2.0.1 (Plugin).

pub fn BarometerBricklet::get_averaging(&self) → ConvertingReceiver<Averaging>¶

Return Object:	moving_average_pressure – Type: u8, Range: [0 to 25], Default: 25 average_pressure – Type: u8, Range: [0 to 10], Default: 10 average_temperature – Type: u8, Range: [0 to 255], Default: 10

Returns the averaging configuration as set by BarometerBricklet::set_averaging.

New in version 2.0.1 (Plugin).

pub fn BarometerBricklet::set_i2c_mode(&self, mode: u8) → ConvertingReceiver<()>¶

Parameters:	mode – Type: u8, Range: See constants, Default: 0

Sets the I2C mode. Possible modes are:

0: Fast (400kHz)
1: Slow (100kHz)

If you have problems with obvious outliers in the Barometer Bricklet measurements, they may be caused by EMI issues. In this case it may be helpful to lower the I2C speed.

It is however not recommended to lower the I2C speed in applications where a high throughput needs to be achieved.

The following constants are available for this function:

For mode:

BAROMETER_BRICKLET_I2C_MODE_FAST = 0
BAROMETER_BRICKLET_I2C_MODE_SLOW = 1

New in version 2.0.3 (Plugin).

pub fn BarometerBricklet::get_i2c_mode(&self) → ConvertingReceiver<u8>¶

Returns:	mode – Type: u8, Range: See constants, Default: 0

Returns the I2C mode as set by BarometerBricklet::set_i2c_mode.

The following constants are available for this function:

For mode:

BAROMETER_BRICKLET_I2C_MODE_FAST = 0
BAROMETER_BRICKLET_I2C_MODE_SLOW = 1

New in version 2.0.3 (Plugin).

Returns the debounce period as set by BarometerBricklet::set_debounce_period.

Callbacks¶

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done with the corresponding get_*_callback_receiver function, which returns a receiver for callback events.

Note

Using callbacks for recurring events is always preferred compared to using getters. It will use less USB bandwidth and the latency will be a lot better, since there is no round trip time.

pub fn BarometerBricklet::get_air_pressure_callback_receiver(&self) → ConvertingCallbackReceiver<i32>¶

Event:	air_pressure – Type: i32, Unit: 1/1000 hPa, Range: [10000 to 1200000]

Receivers created with this function receive Air Pressure events.

This callback is triggered periodically with the period that is set by BarometerBricklet::set_air_pressure_callback_period. The received variable is the air pressure of the air pressure sensor.

The BarometerBricklet::get_air_pressure_callback_receiver callback is only triggered if the air pressure has changed since the last triggering.

pub fn BarometerBricklet::get_altitude_callback_receiver(&self) → ConvertingCallbackReceiver<i32>¶

Event:	altitude – Type: i32, Unit: 1 cm, Range: [-2³¹ to 2³¹ - 1]

Receivers created with this function receive Altitude events.

This callback is triggered periodically with the period that is set by BarometerBricklet::set_altitude_callback_period. The received variable is the altitude of the air pressure sensor.

The BarometerBricklet::get_altitude_callback_receiver callback is only triggered if the altitude has changed since the last triggering.

pub fn BarometerBricklet::get_air_pressure_reached_callback_receiver(&self) → ConvertingCallbackReceiver<i32>¶

Event:	air_pressure – Type: i32, Unit: 1/1000 hPa, Range: [10000 to 1200000]

Receivers created with this function receive Air Pressure Reached events.

This callback is triggered when the threshold as set by BarometerBricklet::set_air_pressure_callback_threshold is reached. The received variable is the air pressure of the air pressure sensor.

If the threshold keeps being reached, the callback is triggered periodically with the period as set by BarometerBricklet::set_debounce_period.

pub fn BarometerBricklet::get_altitude_reached_callback_receiver(&self) → ConvertingCallbackReceiver<i32>¶

Event:	altitude – Type: i32, Unit: 1 cm, Range: [-2³¹ to 2³¹ - 1]

Receivers created with this function receive Altitude Reached events.

This callback is triggered when the threshold as set by BarometerBricklet::set_altitude_callback_threshold is reached. The received variable is the altitude of the air pressure sensor.

If the threshold keeps being reached, the callback is triggered periodically with the period as set by BarometerBricklet::set_debounce_period.

Virtual Functions¶

Virtual functions don't communicate with the device itself, but operate only on the API bindings device object. They can be called without the corresponding IP Connection object being connected.

pub fn BarometerBricklet::get_api_version(&self) → [u8; 3]¶

Return Object:	api_version – Type: [u8; 3] 0: major – Type: u8, Range: [0 to 255] 1: minor – Type: u8, Range: [0 to 255] 2: revision – Type: u8, Range: [0 to 255]

Returns the version of the API definition implemented by this API bindings. This is neither the release version of this API bindings nor does it tell you anything about the represented Brick or Bricklet.

pub fn BarometerBricklet::get_response_expected(&mut self, function_id: u8) → bool¶

Parameters:	function_id – Type: u8, Range: See constants
Returns:	response_expected – Type: bool

Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.

For getter functions this is enabled by default and cannot be disabled, because those functions will always send a response. For callback configuration functions it is enabled by default too, but can be disabled by BarometerBricklet::set_response_expected. For setter functions it is disabled by default and can be enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For function_id:

BAROMETER_BRICKLET_FUNCTION_SET_AIR_PRESSURE_CALLBACK_PERIOD = 3
BAROMETER_BRICKLET_FUNCTION_SET_ALTITUDE_CALLBACK_PERIOD = 5
BAROMETER_BRICKLET_FUNCTION_SET_AIR_PRESSURE_CALLBACK_THRESHOLD = 7
BAROMETER_BRICKLET_FUNCTION_SET_ALTITUDE_CALLBACK_THRESHOLD = 9
BAROMETER_BRICKLET_FUNCTION_SET_DEBOUNCE_PERIOD = 11
BAROMETER_BRICKLET_FUNCTION_SET_REFERENCE_AIR_PRESSURE = 13
BAROMETER_BRICKLET_FUNCTION_SET_AVERAGING = 20
BAROMETER_BRICKLET_FUNCTION_SET_I2C_MODE = 22

pub fn BarometerBricklet::set_response_expected(&mut self, function_id: u8, response_expected: bool) → ()¶

Parameters:	function_id – Type: u8, Range: See constants response_expected – Type: bool

Changes the response expected flag of the function specified by the function ID parameter. This flag can only be changed for setter (default value: false) and callback configuration functions (default value: true). For getter functions it is always enabled.

The following constants are available for this function:

For function_id:

BAROMETER_BRICKLET_FUNCTION_SET_AIR_PRESSURE_CALLBACK_PERIOD = 3
BAROMETER_BRICKLET_FUNCTION_SET_ALTITUDE_CALLBACK_PERIOD = 5
BAROMETER_BRICKLET_FUNCTION_SET_AIR_PRESSURE_CALLBACK_THRESHOLD = 7
BAROMETER_BRICKLET_FUNCTION_SET_ALTITUDE_CALLBACK_THRESHOLD = 9

BAROMETER_BRICKLET_FUNCTION_SET_REFERENCE_AIR_PRESSURE = 13
BAROMETER_BRICKLET_FUNCTION_SET_AVERAGING = 20
BAROMETER_BRICKLET_FUNCTION_SET_I2C_MODE = 22

pub fn BarometerBricklet::set_response_expected_all(&mut self, response_expected: bool) → ()¶

Parameters:	response_expected – Type: bool

Changes the response expected flag for all setter and callback configuration functions of this device at once.

Constants¶

pub const BarometerBricklet::DEVICE_IDENTIFIER¶

This constant is used to identify a Barometer Bricklet.

The BarometerBricklet::get_identity function and the IpConnection::get_enumerate_callback_receiver callback of the IP Connection have a device_identifier parameter to specify the Brick's or Bricklet's type.

pub const BarometerBricklet::DEVICE_DISPLAY_NAME¶: This constant represents the human readable name of a Barometer Bricklet.
