Basic Functions¶

class BrickletIndustrialDualAnalogInV2(String uid, IPConnection ipcon)¶

Parameters:	uid – Type: String ipcon – Type: IPConnection
Returns:	industrialDualAnalogInV2 – Type: BrickletIndustrialDualAnalogInV2

Creates an object with the unique device ID uid.

In MATLAB:

import com.tinkerforge.BrickletIndustrialDualAnalogInV2;

industrialDualAnalogInV2 = BrickletIndustrialDualAnalogInV2('YOUR_DEVICE_UID', ipcon);

In Octave:

industrialDualAnalogInV2 = java_new("com.tinkerforge.BrickletIndustrialDualAnalogInV2", "YOUR_DEVICE_UID", ipcon);

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

int BrickletIndustrialDualAnalogInV2.getVoltage(int channel)¶

Parameters:	channel – Type: int, Range: [0 to 1]
Returns:	voltage – Type: int, Unit: 1 mV, Range: [-35000 to 35000]

Returns the voltage for the given channel.

If you want to get the value periodically, it is recommended to use the VoltageCallback callback. You can set the callback configuration with setVoltageCallbackConfiguration().

void BrickletIndustrialDualAnalogInV2.setChannelLEDConfig(int channel, int config)¶

Parameters:	channel – Type: int, Range: [0 to 1] config – Type: int, Range: See constants, Default: 3

Each channel has a corresponding LED. You can turn the LED off, on or show a heartbeat. You can also set the LED to "Channel Status". In this mode the LED can either be turned on with a pre-defined threshold or the intensity of the LED can change with the measured value.

You can configure the channel status behavior with setChannelLEDStatusConfig().

By default all channel LEDs are configured as "Channel Status".

The following constants are available for this function:

For config:

• BrickletIndustrialDualAnalogInV2.CHANNEL_LED_CONFIG_OFF = 0
• BrickletIndustrialDualAnalogInV2.CHANNEL_LED_CONFIG_ON = 1
• BrickletIndustrialDualAnalogInV2.CHANNEL_LED_CONFIG_SHOW_HEARTBEAT = 2
• BrickletIndustrialDualAnalogInV2.CHANNEL_LED_CONFIG_SHOW_CHANNEL_STATUS = 3

int BrickletIndustrialDualAnalogInV2.getChannelLEDConfig(int channel)¶

Parameters:	channel – Type: int, Range: [0 to 1]
Returns:	config – Type: int, Range: See constants, Default: 3

Returns the channel LED configuration as set by setChannelLEDConfig()

The following constants are available for this function:

For config:

• BrickletIndustrialDualAnalogInV2.CHANNEL_LED_CONFIG_OFF = 0
• BrickletIndustrialDualAnalogInV2.CHANNEL_LED_CONFIG_ON = 1
• BrickletIndustrialDualAnalogInV2.CHANNEL_LED_CONFIG_SHOW_HEARTBEAT = 2
• BrickletIndustrialDualAnalogInV2.CHANNEL_LED_CONFIG_SHOW_CHANNEL_STATUS = 3

void BrickletIndustrialDualAnalogInV2.setChannelLEDStatusConfig(int channel, int min, int max, int config)¶

Parameters:	channel – Type: int, Range: [0 to 1] min – Type: int, Unit: 1 mV, Range: [-231 to 231 - 1], Default: 0 max – Type: int, Unit: 1 mV, Range: [-231 to 231 - 1], Default: 10000 config – Type: int, Range: See constants, Default: 1

Sets the channel LED status config. This config is used if the channel LED is configured as "Channel Status", see setChannelLEDConfig().

For each channel you can choose between threshold and intensity mode.

In threshold mode you can define a positive or a negative threshold. For a positive threshold set the "min" parameter to the threshold value in mV above which the LED should turn on and set the "max" parameter to 0. Example: If you set a positive threshold of 10V, the LED will turn on as soon as the voltage exceeds 10V and turn off again if it goes below 10V. For a negative threshold set the "max" parameter to the threshold value in mV below which the LED should turn on and set the "min" parameter to 0. Example: If you set a negative threshold of 10V, the LED will turn on as soon as the voltage goes below 10V and the LED will turn off when the voltage exceeds 10V.

In intensity mode you can define a range in mV that is used to scale the brightness of the LED. Example with min=4V, max=20V: The LED is off at 4V, on at 20V and the brightness is linearly scaled between the values 4V and 20V. If the min value is greater than the max value, the LED brightness is scaled the other way around.

The following constants are available for this function:

For config:

• BrickletIndustrialDualAnalogInV2.CHANNEL_LED_STATUS_CONFIG_THRESHOLD = 0
• BrickletIndustrialDualAnalogInV2.CHANNEL_LED_STATUS_CONFIG_INTENSITY = 1

Callback Configuration Functions¶

void BrickletIndustrialDualAnalogInV2.setVoltageCallbackConfiguration(int channel, long period, boolean valueHasToChange, char option, int min, int max)¶

Parameters:	channel – Type: int, Range: [0 to 1] period – Type: long, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0 valueHasToChange – Type: boolean, Default: false option – Type: char, Range: See constants, Default: 'x' min – Type: int, Unit: 1 mV, Range: [-231 to 231 - 1], Default: 0 max – Type: int, Unit: 1 mV, Range: [-231 to 231 - 1], Default: 0

The period is the period with which the VoltageCallback callback is triggered periodically. A value of 0 turns the callback off.

If the value has to change-parameter is set to true, the callback is only triggered after the value has changed. If the value didn't change within the period, the callback is triggered immediately on change.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

It is furthermore possible to constrain the callback with thresholds.

The option-parameter together with min/max sets a threshold for the VoltageCallback callback.

The following options are possible:

Option	Description
'x'	Threshold is turned off
'o'	Threshold is triggered when the value is outside the min and max values
'i'	Threshold is triggered when the value is inside or equal to the min and max values
'<'	Threshold is triggered when the value is smaller than the min value (max is ignored)
'>'	Threshold is triggered when the value is greater than the min value (max is ignored)

If the option is set to 'x' (threshold turned off) the callback is triggered with the fixed period.

The following constants are available for this function:

For option:

• BrickletIndustrialDualAnalogInV2.THRESHOLD_OPTION_OFF = 'x'
• BrickletIndustrialDualAnalogInV2.THRESHOLD_OPTION_OUTSIDE = 'o'
• BrickletIndustrialDualAnalogInV2.THRESHOLD_OPTION_INSIDE = 'i'
• BrickletIndustrialDualAnalogInV2.THRESHOLD_OPTION_SMALLER = '<'
• BrickletIndustrialDualAnalogInV2.THRESHOLD_OPTION_GREATER = '>'

Parameters:	channel – Type: int, Range: [0 to 1]
Return Object:	period – Type: long, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0 valueHasToChange – Type: boolean, Default: false option – Type: char, Range: See constants, Default: 'x' min – Type: int, Unit: 1 mV, Range: [-231 to 231 - 1], Default: 0 max – Type: int, Unit: 1 mV, Range: [-231 to 231 - 1], Default: 0

Returns the callback configuration as set by setVoltageCallbackConfiguration().

The following constants are available for this function:

For option:

• BrickletIndustrialDualAnalogInV2.THRESHOLD_OPTION_OFF = 'x'
• BrickletIndustrialDualAnalogInV2.THRESHOLD_OPTION_OUTSIDE = 'o'
• BrickletIndustrialDualAnalogInV2.THRESHOLD_OPTION_INSIDE = 'i'
• BrickletIndustrialDualAnalogInV2.THRESHOLD_OPTION_SMALLER = '<'
• BrickletIndustrialDualAnalogInV2.THRESHOLD_OPTION_GREATER = '>'

void BrickletIndustrialDualAnalogInV2.setAllVoltagesCallbackConfiguration(long period, boolean valueHasToChange)¶

Parameters:	period – Type: long, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0 valueHasToChange – Type: boolean, Default: false

The period is the period with which the AllVoltagesCallback callback is triggered periodically. A value of 0 turns the callback off.

If the value has to change-parameter is set to true, the callback is only triggered after at least one of the values has changed. If the values didn't change within the period, the callback is triggered immediately on change.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

New in version 2.0.6 (Plugin).

BrickletIndustrialDualAnalogInV2.AllVoltagesCallbackConfiguration BrickletIndustrialDualAnalogInV2.getAllVoltagesCallbackConfiguration()¶

Return Object:	period – Type: long, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0 valueHasToChange – Type: boolean, Default: false

Returns the callback configuration as set by setAllVoltagesCallbackConfiguration().

New in version 2.0.6 (Plugin).

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.

callback BrickletIndustrialDualAnalogInV2.VoltageCallback¶

Event Object:	channel – Type: int, Range: [0 to 1] voltage – Type: int, Unit: 1 mV, Range: [-35000 to 35000]

This callback is triggered periodically according to the configuration set by setVoltageCallbackConfiguration().

The parameter is the same as getVoltage().

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 addVoltageCallback() function. An added callback function can be removed with the removeVoltageCallback() function.

callback BrickletIndustrialDualAnalogInV2.AllVoltagesCallback¶

Event Object:	voltages – Type: int[], Length: 2, Unit: 1 mV, Range: [-35000 to 35000]

This callback is triggered periodically according to the configuration set by setAllVoltagesCallbackConfiguration().

The parameters are the same as getAllVoltages().

New in version 2.0.6 (Plugin).

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 addAllVoltagesCallback() function. An added callback function can be removed with the removeAllVoltagesCallback() function.

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.

short[] BrickletIndustrialDualAnalogInV2.getAPIVersion()¶

Return Object:	apiVersion – Type: short[], Length: 3 1: major – Type: short, Range: [0 to 255] 2: minor – Type: short, Range: [0 to 255] 3: revision – Type: short, 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.

boolean BrickletIndustrialDualAnalogInV2.getResponseExpected(byte functionId)¶

Parameters:	functionId – Type: byte, 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 functionId:

• BrickletIndustrialDualAnalogInV2.FUNCTION_SET_VOLTAGE_CALLBACK_CONFIGURATION = 2
• BrickletIndustrialDualAnalogInV2.FUNCTION_SET_SAMPLE_RATE = 5
• BrickletIndustrialDualAnalogInV2.FUNCTION_SET_CALIBRATION = 7
• BrickletIndustrialDualAnalogInV2.FUNCTION_SET_CHANNEL_LED_CONFIG = 10
• BrickletIndustrialDualAnalogInV2.FUNCTION_SET_CHANNEL_LED_STATUS_CONFIG = 12
• BrickletIndustrialDualAnalogInV2.FUNCTION_SET_ALL_VOLTAGES_CALLBACK_CONFIGURATION = 15
• BrickletIndustrialDualAnalogInV2.FUNCTION_SET_WRITE_FIRMWARE_POINTER = 237

• BrickletIndustrialDualAnalogInV2.FUNCTION_RESET = 243
• BrickletIndustrialDualAnalogInV2.FUNCTION_WRITE_UID = 248

void BrickletIndustrialDualAnalogInV2.setResponseExpected(byte functionId, boolean responseExpected)¶

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

The following constants are available for this function:

For functionId:

• BrickletIndustrialDualAnalogInV2.FUNCTION_SET_VOLTAGE_CALLBACK_CONFIGURATION = 2
• BrickletIndustrialDualAnalogInV2.FUNCTION_SET_SAMPLE_RATE = 5
• BrickletIndustrialDualAnalogInV2.FUNCTION_SET_CALIBRATION = 7
• BrickletIndustrialDualAnalogInV2.FUNCTION_SET_CHANNEL_LED_CONFIG = 10
• BrickletIndustrialDualAnalogInV2.FUNCTION_SET_CHANNEL_LED_STATUS_CONFIG = 12

• BrickletIndustrialDualAnalogInV2.FUNCTION_RESET = 243
• BrickletIndustrialDualAnalogInV2.FUNCTION_WRITE_UID = 248

void BrickletIndustrialDualAnalogInV2.setResponseExpectedAll(boolean responseExpected)¶

Parameters:	responseExpected – Type: boolean

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

Internal Functions¶

Internal functions are used for maintenance tasks such as flashing a new firmware of changing the UID of a Bricklet. These task should be performed using Brick Viewer instead of using the internal functions directly.

int BrickletIndustrialDualAnalogInV2.setBootloaderMode(int mode)¶

Parameters:	mode – Type: int, Range: See constants
Returns:	status – Type: int, Range: See constants

Sets the bootloader mode and returns the status after the requested mode change was instigated.

You can change from bootloader mode to firmware mode and vice versa. A change from bootloader mode to firmware mode will only take place if the entry function, device identifier and CRC are present and correct.

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

The following constants are available for this function:

For mode:

• BrickletIndustrialDualAnalogInV2.BOOTLOADER_MODE_BOOTLOADER = 0
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_MODE_FIRMWARE = 1
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_MODE_BOOTLOADER_WAIT_FOR_REBOOT = 2
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_REBOOT = 3
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_ERASE_AND_REBOOT = 4

For status:

• BrickletIndustrialDualAnalogInV2.BOOTLOADER_STATUS_OK = 0
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_STATUS_INVALID_MODE = 1
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_STATUS_NO_CHANGE = 2
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_STATUS_ENTRY_FUNCTION_NOT_PRESENT = 3
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_STATUS_DEVICE_IDENTIFIER_INCORRECT = 4
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_STATUS_CRC_MISMATCH = 5

int BrickletIndustrialDualAnalogInV2.getBootloaderMode()¶

Returns:	mode – Type: int, Range: See constants

Returns the current bootloader mode, see setBootloaderMode().

The following constants are available for this function:

For mode:

• BrickletIndustrialDualAnalogInV2.BOOTLOADER_MODE_BOOTLOADER = 0
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_MODE_FIRMWARE = 1
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_MODE_BOOTLOADER_WAIT_FOR_REBOOT = 2
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_REBOOT = 3
• BrickletIndustrialDualAnalogInV2.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_ERASE_AND_REBOOT = 4

void BrickletIndustrialDualAnalogInV2.setWriteFirmwarePointer(long pointer)¶

Parameters:	pointer – Type: long, Unit: 1 B, Range: [0 to 232 - 1]

Sets the firmware pointer for writeFirmware(). The pointer has to be increased by chunks of size 64. The data is written to flash every 4 chunks (which equals to one page of size 256).

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

int BrickletIndustrialDualAnalogInV2.writeFirmware(int[] data)¶

Parameters:	data – Type: int[], Length: 64, Range: [0 to 255]
Returns:	status – Type: int, Range: [0 to 255]

Writes 64 Bytes of firmware at the position as written by setWriteFirmwarePointer() before. The firmware is written to flash every 4 chunks.

You can only write firmware in bootloader mode.

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

void BrickletIndustrialDualAnalogInV2.writeUID(long uid)¶

Parameters:	uid – Type: long, Range: [0 to 232 - 1]

Writes a new UID into flash. If you want to set a new UID you have to decode the Base58 encoded UID string into an integer first.

We recommend that you use Brick Viewer to change the UID.

long BrickletIndustrialDualAnalogInV2.readUID()¶

Returns:	uid – Type: long, Range: [0 to 232 - 1]

Returns the current UID as an integer. Encode as Base58 to get the usual string version.

Constants¶

int BrickletIndustrialDualAnalogInV2.DEVICE_IDENTIFIER¶

This constant is used to identify a Industrial Dual Analog In Bricklet 2.0.

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

String BrickletIndustrialDualAnalogInV2.DEVICE_DISPLAY_NAME¶

This constant represents the human readable name of a Industrial Dual Analog In Bricklet 2.0.
