Implementations

impl TemperatureBricklet

pub const DEVICE_IDENTIFIER: u16 = 216u16

pub const DEVICE_DISPLAY_NAME: &'static str = "Temperature Bricklet"

pub fn new(uid: &str, ip_connection: &IpConnection) -> TemperatureBricklet

Creates an object with the unique device ID uid. This object can then be used after the IP Connection ip_connection is connected.

pub fn get_response_expected(
    &mut self,
    fun: TemperatureBrickletFunction
) -> Result<bool, GetResponseExpectedError>

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 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 send and errors are silently ignored, because they cannot be detected.

See set_response_expected for the list of function ID constants available for this function.

pub fn set_response_expected(
    &mut self,
    fun: TemperatureBrickletFunction,
    response_expected: bool
) -> Result<(), SetResponseExpectedError>

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.

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 send and errors are silently ignored, because they cannot be detected.

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

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

pub fn get_temperature_callback_receiver(
    &self
) -> ConvertingCallbackReceiver<i16>

This receiver is triggered periodically with the period that is set by Set Temperature Receiver Period. The parameter is the temperature of the sensor.

The get_temperature_callback_receiver receiver is only triggered if the temperature has changed since the last triggering.

pub fn get_temperature_reached_callback_receiver(
    &self
) -> ConvertingCallbackReceiver<i16>

This receiver is triggered when the threshold as set by Set Temperature Receiver Threshold is reached. The parameter is the temperature of the sensor.

If the threshold keeps being reached, the receiver is triggered periodically with the period as set by Set Debounce Period.

pub fn get_temperature(&self) -> ConvertingReceiver<i16>

Returns the temperature of the sensor. The value has a range of -2500 to 8500 and is given in °C/100, e.g. a value of 4223 means that a temperature of 42.23 °C is measured.

If you want to get the temperature periodically, it is recommended to use the get_temperature_callback_receiver receiver and set the period with Set Temperature Receiver Period.

pub fn set_temperature_callback_period(
    &self,
    period: u32
) -> ConvertingReceiver<()>

Sets the period in ms with which the get_temperature_callback_receiver receiver is triggered periodically. A value of 0 turns the receiver off.

The get_temperature_callback_receiver receiver is only triggered if the temperature has changed since the last triggering.

The default value is 0.

pub fn get_temperature_callback_period(&self) -> ConvertingReceiver<u32>

Returns the period as set by Set Temperature Receiver Period.

pub fn set_temperature_callback_threshold(
    &self,
    option: char,
    min: i16,
    max: i16
) -> ConvertingReceiver<()>

Sets the thresholds for the get_temperature_reached_callback_receiver receiver.

The following options are possible:

Option	Description
‘x’	Receiver is turned off
‘o’	Receiver is triggered when the temperature is outside the min and max values
‘i’	Receiver is triggered when the temperature is inside the min and max values
‘<’	Receiver is triggered when the temperature is smaller than the min value (max is ignored)
‘>’	Receiver is triggered when the temperature is greater than the min value (max is ignored)

The default value is (‘x’, 0, 0).

Associated constants:

• TEMPERATUREBRICKLET_THRESHOLD_OPTION_OFF
• TEMPERATUREBRICKLET_THRESHOLD_OPTION_OUTSIDE
• TEMPERATUREBRICKLET_THRESHOLD_OPTION_INSIDE
• TEMPERATUREBRICKLET_THRESHOLD_OPTION_SMALLER
• TEMPERATUREBRICKLET_THRESHOLD_OPTION_GREATER

pub fn get_temperature_callback_threshold(
    &self
) -> ConvertingReceiver<TemperatureCallbackThreshold>

Returns the threshold as set by Set Temperature Receiver Threshold.

Associated constants:

• TEMPERATUREBRICKLET_THRESHOLD_OPTION_OFF
• TEMPERATUREBRICKLET_THRESHOLD_OPTION_OUTSIDE
• TEMPERATUREBRICKLET_THRESHOLD_OPTION_INSIDE
• TEMPERATUREBRICKLET_THRESHOLD_OPTION_SMALLER
• TEMPERATUREBRICKLET_THRESHOLD_OPTION_GREATER

pub fn set_debounce_period(&self, debounce: u32) -> ConvertingReceiver<()>

Sets the period in ms with which the threshold receiver

• get_temperature_reached_callback_receiver

is triggered, if the threshold

• Set Temperature Receiver Threshold

keeps being reached.

The default value is 100.

pub fn get_debounce_period(&self) -> ConvertingReceiver<u32>

Returns the debounce period as set by Set Debounce Period.

pub fn set_i2c_mode(&self, mode: u8) -> ConvertingReceiver<()>

Sets the I2C mode. Possible modes are:

• 0: Fast (400kHz, default)
• 1: Slow (100kHz)

If you have problems with obvious outliers in the Temperature 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.

.. versionadded:: 2.0.1$nbsp;(Plugin)

Associated constants:

• TEMPERATUREBRICKLET_I2C_MODE_FAST
• TEMPERATUREBRICKLET_I2C_MODE_SLOW

pub fn get_i2c_mode(&self) -> ConvertingReceiver<u8>

Returns the I2C mode as set by Set I2C Mode.

.. versionadded:: 2.0.1$nbsp;(Plugin)

Associated constants:

• TEMPERATUREBRICKLET_I2C_MODE_FAST
• TEMPERATUREBRICKLET_I2C_MODE_SLOW

pub fn get_identity(&self) -> ConvertingReceiver<Identity>

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be ‘a’, ‘b’, ‘c’ or ‘d’.

The device identifier numbers can be found here. |device_identifier_constant|
