Basic Functions¶

new BrickletDistanceIR(uid, ipcon)¶

Parameters:	uid – Type: string ipcon – Type: IPConnection
Returns:	distanceIR – Type: BrickletDistanceIR

Creates an object with the unique device ID uid:

var distanceIR = new BrickletDistanceIR("YOUR_DEVICE_UID", ipcon);

This object can then be used after the IP Connection is connected.

BrickletDistanceIR.getDistance([returnCallback][, errorCallback])¶

Callback Parameters:	distance – Type: int, Unit: 1 mm, Range: [0 to 216 - 1]
Returns:	undefined

Returns the distance measured by the sensor. Possible distance ranges are 40 to 300, 100 to 800 and 200 to 1500, depending on the selected IR sensor.

If you want to get the distance periodically, it is recommended to use the CALLBACK_DISTANCE callback and set the period with setDistanceCallbackPeriod().

Advanced Functions¶

BrickletDistanceIR.getAnalogValue([returnCallback][, errorCallback])¶

Callback Parameters:	value – Type: int, Range: [0 to 212 - 1]
Returns:	undefined

Returns the value as read by a 12-bit analog-to-digital converter.

Note

The value returned by getDistance() is averaged over several samples to yield less noise, while getAnalogValue() gives back raw unfiltered analog values. The only reason to use getAnalogValue() is, if you need the full resolution of the analog-to-digital converter.

If you want the analog value periodically, it is recommended to use the CALLBACK_ANALOG_VALUE callback and set the period with setAnalogValueCallbackPeriod().

BrickletDistanceIR.setSamplingPoint(position, distance[, returnCallback][, errorCallback])¶

Parameters:	position – Type: int, Range: [0 to 127] distance – Type: int, Unit: 1/10 mm, Range: [0 to 216 - 1]
Callback Parameters:	undefined
Returns:	undefined

Sets a sampling point value to a specific position of the lookup table. The lookup table comprises 128 equidistant analog values with corresponding distances.

If you measure a distance of 50cm at the analog value 2048, you should call this function with (64, 5000). The utilized analog-to-digital converter has a resolution of 12 bit. With 128 sampling points on the whole range, this means that every sampling point has a size of 32 analog values. Thus the analog value 2048 has the corresponding sampling point 64 = 2048/32.

Sampling points are saved on the EEPROM of the Distance IR Bricklet and loaded again on startup.

Note

An easy way to calibrate the sampling points of the Distance IR Bricklet is implemented in the Brick Viewer. If you want to calibrate your Bricklet it is highly recommended to use this implementation.

BrickletDistanceIR.getSamplingPoint(position[, returnCallback][, errorCallback])¶

Parameters:	position – Type: int, Range: [0 to 127]
Callback Parameters:	distance – Type: int, Unit: 1/10 mm, Range: [0 to 216 - 1]
Returns:	undefined

Returns the distance to a sampling point position as set by setSamplingPoint().

BrickletDistanceIR.getIdentity([returnCallback][, errorCallback])¶

Callback Parameters:

Callbacks¶

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done with the on() function of the device object. The first parameter is the callback ID and the second parameter the callback function:

distanceIR.on(BrickletDistanceIR.CALLBACK_EXAMPLE,
    function (param) {
        console.log(param);
    }
);

The available constants with inherent number and type of parameters are described below.

BrickletDistanceIR.CALLBACK_DISTANCE¶

Callback Parameters:	distance – Type: int, Unit: 1 mm, Range: [0 to 216 - 1]

This callback is triggered periodically with the period that is set by setDistanceCallbackPeriod(). The parameter is the distance of the sensor.

The CALLBACK_DISTANCE callback is only triggered if the distance has changed since the last triggering.

BrickletDistanceIR.CALLBACK_ANALOG_VALUE¶

Callback Parameters:	value – Type: int, Range: [0 to 212 - 1]

This callback is triggered periodically with the period that is set by setAnalogValueCallbackPeriod(). The parameter is the analog value of the sensor.

The CALLBACK_ANALOG_VALUE callback is only triggered if the analog value has changed since the last triggering.

BrickletDistanceIR.CALLBACK_DISTANCE_REACHED¶

Callback Parameters:	distance – Type: int, Unit: 1 mm, Range: [0 to 216 - 1]

This callback is triggered when the threshold as set by setDistanceCallbackThreshold() is reached. The parameter is the distance of the sensor.

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

BrickletDistanceIR.CALLBACK_ANALOG_VALUE_REACHED¶

Callback Parameters:	value – Type: int, Range: [0 to 212 - 1]

This callback is triggered when the threshold as set by setAnalogValueCallbackThreshold() is reached. The parameter is the analog value of the sensor.

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

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.

BrickletDistanceIR.getAPIVersion()¶

Returns:	apiVersion – Type: [int, ...], Length: 3 0: major – Type: int, Range: [0 to 255] 1: minor – Type: int, Range: [0 to 255] 2: revision – Type: int, 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.

BrickletDistanceIR.getResponseExpected(functionId[, errorCallback])¶

Parameters:	functionId – Type: int, 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 sent and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For function_id:

• BrickletDistanceIR.FUNCTION_SET_SAMPLING_POINT = 3
• BrickletDistanceIR.FUNCTION_SET_DISTANCE_CALLBACK_PERIOD = 5
• BrickletDistanceIR.FUNCTION_SET_ANALOG_VALUE_CALLBACK_PERIOD = 7
• BrickletDistanceIR.FUNCTION_SET_DISTANCE_CALLBACK_THRESHOLD = 9
• BrickletDistanceIR.FUNCTION_SET_ANALOG_VALUE_CALLBACK_THRESHOLD = 11
• BrickletDistanceIR.FUNCTION_SET_DEBOUNCE_PERIOD = 13

BrickletDistanceIR.setResponseExpected(functionId, responseExpected[, errorCallback])¶

Parameters:	functionId – Type: int, Range: See constants responseExpected – Type: boolean
Returns:	undefined

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

The following constants are available for this function:

For function_id:

• BrickletDistanceIR.FUNCTION_SET_SAMPLING_POINT = 3
• BrickletDistanceIR.FUNCTION_SET_DISTANCE_CALLBACK_PERIOD = 5
• BrickletDistanceIR.FUNCTION_SET_ANALOG_VALUE_CALLBACK_PERIOD = 7
• BrickletDistanceIR.FUNCTION_SET_DISTANCE_CALLBACK_THRESHOLD = 9
• BrickletDistanceIR.FUNCTION_SET_ANALOG_VALUE_CALLBACK_THRESHOLD = 11
• BrickletDistanceIR.FUNCTION_SET_DEBOUNCE_PERIOD = 13

BrickletDistanceIR.setResponseExpectedAll(responseExpected)¶

Parameters:	responseExpected – Type: boolean
Returns:	undefined

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

Constants¶

BrickletDistanceIR.DEVICE_IDENTIFIER¶

This constant is used to identify a Distance IR Bricklet.

The getIdentity() function and the IPConnection.CALLBACK_ENUMERATE callback of the IP Connection have a device_identifier parameter to specify the Brick's or Bricklet's type.

BrickletDistanceIR.DEVICE_DISPLAY_NAME¶

This constant represents the human readable name of a Distance IR Bricklet.
