API

Generally, every method of the MATLAB bindings that returns a value can throw a TimeoutException. This exception gets thrown if the device did not respond. If a cable based connection is used, it is unlikely that this exception gets thrown (assuming nobody unplugs the device). However, if a wireless connection is used, timeouts will occur if the distance to the device gets too big.

Beside the TimeoutException there is also a NotConnectedException that is thrown if a method needs to communicate with the device while the IP Connection is not connected.

Since the MATLAB bindings are based on Java and Java does not support multiple return values and return by reference is not possible for primitive types, we use small classes that only consist of member variables. The member variables of the returned objects are described in the corresponding method descriptions.

The package for all Brick/Bricklet bindings and the IP Connection is com.tinkerforge.*

All methods listed below are thread-safe.

Basic Functions

class BrickletTemperatureIR(String uid, IPConnection ipcon)
Parameters:
  • uid – Type: String
  • ipcon – Type: IPConnection
Returns:
  • temperatureIR – Type: BrickletTemperatureIR

Creates an object with the unique device ID uid.

In MATLAB:

import com.tinkerforge.BrickletTemperatureIR;

temperatureIR = BrickletTemperatureIR('YOUR_DEVICE_UID', ipcon);

In Octave:

temperatureIR = java_new("com.tinkerforge.BrickletTemperatureIR", "YOUR_DEVICE_UID", ipcon);

This object can then be used after the IP Connection is connected (see examples above).

short BrickletTemperatureIR.getAmbientTemperature()
Returns:
  • temperature – Type: short, Range: [-215 to 215 - 1]

Returns the ambient temperature of the sensor. The value has a range of -400 to 1250 and is given in °C/10, e.g. a value of 423 means that an ambient temperature of 42.3 °C is measured.

If you want to get the ambient temperature periodically, it is recommended to use the AmbientTemperatureCallback callback and set the period with setAmbientTemperatureCallbackPeriod().

short BrickletTemperatureIR.getObjectTemperature()
Returns:
  • temperature – Type: short, Range: [-215 to 215 - 1]

Returns the object temperature of the sensor, i.e. the temperature of the surface of the object the sensor is aimed at. The value has a range of -700 to 3800 and is given in °C/10, e.g. a value of 3001 means that a temperature of 300.1 °C is measured on the surface of the object.

The temperature of different materials is dependent on their emissivity. The emissivity of the material can be set with setEmissivity().

If you want to get the object temperature periodically, it is recommended to use the ObjectTemperatureCallback callback and set the period with setObjectTemperatureCallbackPeriod().

Advanced Functions

void BrickletTemperatureIR.setEmissivity(int emissivity)
Parameters:
  • emissivity – Type: int, Range: [0 to 216 - 1]

Sets the emissivity that is used to calculate the surface temperature as returned by getObjectTemperature().

The emissivity is usually given as a value between 0.0 and 1.0. A list of emissivities of different materials can be found here.

The parameter of setEmissivity() has to be given with a factor of 65535 (16-bit). For example: An emissivity of 0.1 can be set with the value 6553, an emissivity of 0.5 with the value 32767 and so on.

Note

If you need a precise measurement for the object temperature, it is absolutely crucial that you also provide a precise emissivity.

The default emissivity is 1.0 (value of 65535) and the minimum emissivity the sensor can handle is 0.1 (value of 6553).

The emissivity is stored in non-volatile memory and will still be used after a restart or power cycle of the Bricklet.

int BrickletTemperatureIR.getEmissivity()
Returns:
  • emissivity – Type: int, Range: [0 to 216 - 1]

Returns the emissivity as set by setEmissivity().

short[] BrickletTemperatureIR.getAPIVersion()
Returns:
  • apiVersion – Type: short[], Length: 3, Range: [0 to 255]

Returns the version of the API definition (major, minor, revision) 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.

boolean BrickletTemperatureIR.getResponseExpected(short functionId)
Parameters:
  • functionId – Type: short, Range: See constants
Returns:
  • responseExpected – Type: boolean

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 setResponseExpected(). 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.

The following constants are available for this function:

For functionId:

  • BrickletTemperatureIR.FUNCTION_SET_EMISSIVITY = 3
  • BrickletTemperatureIR.FUNCTION_SET_AMBIENT_TEMPERATURE_CALLBACK_PERIOD = 5
  • BrickletTemperatureIR.FUNCTION_SET_OBJECT_TEMPERATURE_CALLBACK_PERIOD = 7
  • BrickletTemperatureIR.FUNCTION_SET_AMBIENT_TEMPERATURE_CALLBACK_THRESHOLD = 9
  • BrickletTemperatureIR.FUNCTION_SET_OBJECT_TEMPERATURE_CALLBACK_THRESHOLD = 11
  • BrickletTemperatureIR.FUNCTION_SET_DEBOUNCE_PERIOD = 13
void BrickletTemperatureIR.setResponseExpected(short functionId, boolean responseExpected)
Parameters:
  • functionId – Type: short, Range: See constants
  • responseExpected – Type: boolean

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.

The following constants are available for this function:

For functionId:

  • BrickletTemperatureIR.FUNCTION_SET_EMISSIVITY = 3
  • BrickletTemperatureIR.FUNCTION_SET_AMBIENT_TEMPERATURE_CALLBACK_PERIOD = 5

  • BrickletTemperatureIR.FUNCTION_SET_AMBIENT_TEMPERATURE_CALLBACK_THRESHOLD = 9
  • BrickletTemperatureIR.FUNCTION_SET_OBJECT_TEMPERATURE_CALLBACK_THRESHOLD = 11
  • BrickletTemperatureIR.FUNCTION_SET_DEBOUNCE_PERIOD = 13
void BrickletTemperatureIR.setResponseExpectedAll(boolean responseExpected)
Parameters:
  • responseExpected – Type: boolean

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

Return Object:
  • uid – Type: String, Length: up to 8
  • connectedUid – Type: String, Length: up to 8
  • position – Type: char
  • hardwareVersion – Type: short[], Length: 3, Range: [0 to 255]

Callbacks

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done with "set" function of MATLAB. The parameters consist of the IP Connection object, the callback name and the callback function. For example, it looks like this in MATLAB:

function my_callback(e)
    fprintf('Parameter: %s\n', e.param);
end

set(device, 'ExampleCallback', @(h, e) my_callback(e));

Due to a difference in the Octave Java support the "set" function cannot be used in Octave. The registration is done with "add*Callback" functions of the device object. It looks like this in Octave:

function my_callback(e)
    fprintf("Parameter: %s\n", e.param);
end

device.addExampleCallback(@my_callback);

It is possible to add several callbacks and to remove them with the corresponding "remove*Callback" function.

The parameters of the callback are passed to the callback function as fields of the structure e, which is derived from the java.util.EventObject class. The available callback names with corresponding structure fields are described below.

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.

callback BrickletTemperatureIR.AmbientTemperatureCallback
Event Object:
  • temperature – Type: short, Range: [-215 to 215 - 1]

This callback is triggered periodically with the period that is set by setAmbientTemperatureCallbackPeriod(). The parameter is the ambient temperature of the sensor.

The AmbientTemperatureCallback callback is only triggered if the ambient temperature has changed since the last triggering.

In MATLAB the set() function can be used to register a callback function to this callback.

In Octave a callback function can be added to this callback using the addAmbientTemperatureCallback() function. An added callback function can be removed with the removeAmbientTemperatureCallback() function.

callback BrickletTemperatureIR.ObjectTemperatureCallback
Event Object:
  • temperature – Type: short, Range: [-215 to 215 - 1]

This callback is triggered periodically with the period that is set by setObjectTemperatureCallbackPeriod(). The parameter is the object temperature of the sensor.

The ObjectTemperatureCallback callback is only triggered if the object temperature has changed since the last triggering.

In MATLAB the set() function can be used to register a callback function to this callback.

In Octave a callback function can be added to this callback using the addObjectTemperatureCallback() function. An added callback function can be removed with the removeObjectTemperatureCallback() function.

callback BrickletTemperatureIR.AmbientTemperatureReachedCallback
Event Object:
  • temperature – Type: short, Range: [-215 to 215 - 1]

This callback is triggered when the threshold as set by setAmbientTemperatureCallbackThreshold() is reached. The parameter is the ambient temperature of the sensor.

If the threshold keeps being reached, the callback is triggered periodically with the period as set by setDebouncePeriod().

In MATLAB the set() function can be used to register a callback function to this callback.

In Octave a callback function can be added to this callback using the addAmbientTemperatureReachedCallback() function. An added callback function can be removed with the removeAmbientTemperatureReachedCallback() function.
