# Mathematica - Industrial Analog Out Bricklet

Note

This Bricklet is currently in the prototype stage and the software/hardware as well as the documentation is in an incomplete state.

This is the description of the Mathematica API bindings for the Industrial Analog Out Bricklet. General information and technical specifications for the Industrial Analog Out Bricklet are summarized in its hardware description.

An installation guide for the Mathematica API bindings is part of their general description.

## Examples

The example code below is Public Domain (CC0 1.0).

## API

Generally, every method of the Mathematica bindings that returns a value can throw a `Tinkerforge.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 plugs the device out). However, if a wireless connection is used, timeouts will occur if the distance to the device gets too big.

Since .NET/Link does not support multiple return values directly, we use the `out` keyword to return multiple values from a method. For further information about the `out` keyword in .NET/Link see the corresponding Mathematica .NET/Link documentation.

The namespace for all Brick/Bricklet bindings and the IPConnection is `Tinkerforge.*`.

### Basic Functions

`BrickletIndustrialAnalogOut`[uid, ipcon] → industrialAnalogOut

  Parameters:

  - uid -- String
  - ipcon -- NETObject[IPConnection]

  Returns:

  - industrialAnalogOut -- NETObject[BrickletIndustrialAnalogOut]

  Creates an object with the unique device ID `uid`:

      industrialAnalogOut=NETNew["Tinkerforge.BrickletIndustrialAnalogOut","YOUR_DEVICE_UID",ipcon]

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

  The .NET runtime has built-in garbage collection that frees objects that are no longer in use by a program. But because Mathematica can not automatically tell when a Mathematica "program" doesn't use a .NET object anymore, this has to be done by the program. For this the ReleaseNETObject[] function is used in the examples.

  For further information about object management in .NET/Link see the corresponding Mathematica .NET/Link documentation.

`BrickletIndustrialAnalogOut``@``Enable`[] → Null

  Enables the output of voltage and current.

  The default is disabled.

`BrickletIndustrialAnalogOut``@``Disable`[] → Null

  Disables the output of voltage and current.

  The default is disabled.

`BrickletIndustrialAnalogOut``@``IsEnabled`[] → enabled

  Returns:

  - enabled -- True/False

  Returns true if output of voltage and current is enabled, false otherwise.

`BrickletIndustrialAnalogOut``@``SetVoltage`[voltage] → Null

  Parameters:

  - voltage -- Integer

  Sets the output voltage in mV.

`BrickletIndustrialAnalogOut``@``GetVoltage`[] → voltage

  Returns:

  - voltage -- Integer

  Returns the voltage as set by `SetVoltage[]`.

`BrickletIndustrialAnalogOut``@``SetCurrent`[current] → Null

  Parameters:

  - current -- Integer

  Sets the output current in µA.

`BrickletIndustrialAnalogOut``@``GetCurrent`[] → current

  Returns:

  - current -- Integer

  Returns the current as set by `SetCurrent[]`.

### Advanced Functions

`BrickletIndustrialAnalogOut``@``SetConfiguration`[voltageRange, currentRange] → Null

  Parameters:

  - voltageRange -- Integer
  - currentRange -- Integer

  Configures the voltage and current range.

  Possible voltage ranges are:

  - 0V to 5V
  - 0V to 10V

  Possible current ranges are:

  - 4mA to 20mA
  - 0mA to 20mA
  - 0mA to 24mA

  The resolution will always be 12 bit. This means, that the precision is higher with a smaller range.

  The following constants are available for this function:

  - BrickletIndustrialAnalogOut`VOLTAGEURANGEU0UTOU5V = 0
  - BrickletIndustrialAnalogOut`VOLTAGEURANGEU0UTOU10V = 1
  - BrickletIndustrialAnalogOut`CURRENTURANGEU4UTOU20MA = 0
  - BrickletIndustrialAnalogOut`CURRENTURANGEU0UTOU20MA = 1
  - BrickletIndustrialAnalogOut`CURRENTURANGEU0UTOU24MA = 2

`BrickletIndustrialAnalogOut``@``GetConfiguration`[out voltageRange, out currentRange] → Null

  Parameters:

  - voltageRange -- Integer
  - currentRange -- Integer

  Returns the configuration as set by `SetConfiguration[]`.

  The following constants are available for this function:

  - BrickletIndustrialAnalogOut`VOLTAGEURANGEU0UTOU5V = 0
  - BrickletIndustrialAnalogOut`VOLTAGEURANGEU0UTOU10V = 1
  - BrickletIndustrialAnalogOut`CURRENTURANGEU4UTOU20MA = 0
  - BrickletIndustrialAnalogOut`CURRENTURANGEU0UTOU20MA = 1
  - BrickletIndustrialAnalogOut`CURRENTURANGEU0UTOU24MA = 2

`BrickletIndustrialAnalogOut``@``GetAPIVersion`[] → {apiVersion1, apiVersion2, apiVersion3}

  Returns:

  - apiVersioni -- Integer

  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.

`BrickletIndustrialAnalogOut``@``GetResponseExpected`[functionId] → responseExpected

  Parameters:

  - functionId -- Integer

  Returns:

  - responseExpected -- True/False

  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.

  See `SetResponseExpected[]` for the list of function ID constants available for this function.

`BrickletIndustrialAnalogOut``@``SetResponseExpected`[functionId, responseExpected] → Null

  Parameters:

  - functionId -- Integer
  - responseExpected -- True/False

  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 and callbacks it is always disabled.

  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 function ID constants are available for this function:

  - BrickletIndustrialAnalogOut`FUNCTIONUENABLE = 1
  - BrickletIndustrialAnalogOut`FUNCTIONUDISABLE = 2
  - BrickletIndustrialAnalogOut`FUNCTIONUSETUVOLTAGE = 4
  - BrickletIndustrialAnalogOut`FUNCTIONUSETUCURRENT = 6
  - BrickletIndustrialAnalogOut`FUNCTIONUSETUCONFIGURATION = 8

`BrickletIndustrialAnalogOut``@``SetResponseExpectedAll`[responseExpected] → Null

  Parameters:

  - responseExpected -- True/False

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

`BrickletIndustrialAnalogOut``@``GetIdentity`[out uid, out connectedUid, out position, out {hardwareVersion1, hardwareVersion2, hardwareVersion3}, out {firmwareVersion1, firmwareVersion2, firmwareVersion3}, out deviceIdentifier] → Null

  Parameters:

  - uid -- String
  - connectedUid -- String
  - position -- Integer
  - hardwareVersioni -- Integer
  - firmwareVersioni -- Integer
  - deviceIdentifier -- Integer

  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. There is also a constant for the device identifier of this Bricklet.

### Constants

`BrickletIndustrialAnalogOut`````DEVICEUIDENTIFIER`

  This constant is used to identify a Industrial Analog Out Bricklet.

  The `GetIdentity[]` function and the `EnumerateCallback` callback of the IP Connection have a `deviceIdentifier` parameter to specify the Brick's or Bricklet's type.
