All methods listed below are thread-safe.




Basic Functions
^^^^^^^^^^^^^^^


.. rb:function:: BrickletVoltageCurrent::new(uid, ipcon) -> voltage_current

 :param uid: str
 :param ipcon: IPConnection

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

 .. code-block:: ruby

    voltage_current = BrickletVoltageCurrent.new 'YOUR_DEVICE_UID', ipcon

 This object can then be used after the IP Connection is connected
 (see examples :ref:`above <voltage_current_bricklet_ruby_examples>`).


.. rb:function:: BrickletVoltageCurrent#get_current -> int


 Returns the current. The value is in mA
 and between -20000mA and 20000mA.
 
 If you want to get the current periodically, it is recommended to use the
 callback :rb:attr:`::CALLBACK_CURRENT <BrickletVoltageCurrent::CALLBACK_CURRENT>` and set the period with 
 :rb:func:`#set_current_callback_period <BrickletVoltageCurrent#set_current_callback_period>`.
 
.. rb:function:: BrickletVoltageCurrent#get_voltage -> int


 Returns the voltage. The value is in mV
 and between 0mV and 36000mV.
 
 If you want to get the voltage periodically, it is recommended to use the
 callback :rb:attr:`::CALLBACK_VOLTAGE <BrickletVoltageCurrent::CALLBACK_VOLTAGE>` and set the period with 
 :rb:func:`#set_voltage_callback_period <BrickletVoltageCurrent#set_voltage_callback_period>`.
 
.. rb:function:: BrickletVoltageCurrent#get_power -> int


 Returns the power. The value is in mW
 and between 0mV and 720000mW.
 
 If you want to get the power periodically, it is recommended to use the
 callback :rb:attr:`::CALLBACK_POWER <BrickletVoltageCurrent::CALLBACK_POWER>` and set the period with 
 :rb:func:`#set_power_callback_period <BrickletVoltageCurrent#set_power_callback_period>`.
 
.. rb:function:: BrickletVoltageCurrent#set_configuration(averaging, voltage_conversion_time, current_conversion_time) -> nil

 :param averaging: int

 :param current_conversion_time: int

 Sets the configuration of the Voltage/Current Bricklet. It is
 possible to configure number of averages as well as
 voltage and current conversion time.

 .. csv-table::
  :header: "Value", "Number of Averages"
  :widths: 20, 20
 
  "0",    "1"
  "1",    "4"
  "2",    "16"

 Voltage/Current conversion:
 
 .. csv-table::
  :header: "Value", "Conversion time"
  :widths: 20, 20
 
  "0",    "140µs"
  "1",    "204µs"

 The default values are 3, 4 and 4 (64, 1.1ms, 1.1ms) for averaging, voltage 
 conversion and current conversion.
 
 The following constants are available for this function:
 
 * BrickletVoltageCurrent::AVERAGING_1 = 0

 The returned array has the values ``averaging``, ``voltage_conversion_time`` and ``current_conversion_time``.



Advanced Functions
^^^^^^^^^^^^^^^^^^

.. rb:function:: BrickletVoltageCurrent#set_calibration(gain_multiplier, gain_divisor) -> nil

 :param gain_multiplier: int
 :param gain_divisor: int

 Since the shunt resistor that is used to measure the current is not
 perfectly precise, it needs to be calibrated by a multiplier and
 divisor if a very precise reading is needed.
 
 For example, if you are expecting a measurement of 1000mA and you
 are measuring 1023mA, you can calibrate the Voltage/Current Bricklet 
 by setting the multiplier to 1000 and the divisor to 1023.
 
.. rb:function:: BrickletVoltageCurrent#get_calibration -> [int, int]


 Returns the calibration as set by :rb:func:`#set_calibration <BrickletVoltageCurrent#set_calibration>`.
 
 The returned array has the values ``gain_multiplier`` and ``gain_divisor``.

.. rb:function:: BrickletVoltageCurrent#get_api_version -> [int, int, int]


 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.
 
.. rb:function:: BrickletVoltageCurrent#get_response_expected(function_id) -> bool

 :param function_id: int

 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
 :rb:func:`#set_response_expected <BrickletVoltageCurrent#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 :rb:func:`#set_response_expected <BrickletVoltageCurrent#set_response_expected>`
 for the list of function ID constants available for this function.
 
.. rb:function:: BrickletVoltageCurrent#set_response_expected(function_id, response_expected) -> nil

 :param function_id: int
 :param response_expected: bool

 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:
 
 * BrickletVoltageCurrent::FUNCTION_SET_CONFIGURATION = 4
 * BrickletVoltageCurrent::FUNCTION_SET_CALIBRATION = 6
 * BrickletVoltageCurrent::FUNCTION_SET_CURRENT_CALLBACK_PERIOD = 8
 * BrickletVoltageCurrent::FUNCTION_SET_VOLTAGE_CALLBACK_PERIOD = 10
 * BrickletVoltageCurrent::FUNCTION_SET_POWER_CALLBACK_PERIOD = 12
 * BrickletVoltageCurrent::FUNCTION_SET_CURRENT_CALLBACK_THRESHOLD = 14
 * BrickletVoltageCurrent::FUNCTION_SET_VOLTAGE_CALLBACK_THRESHOLD = 16
 * BrickletVoltageCurrent::FUNCTION_SET_POWER_CALLBACK_THRESHOLD = 18
 * BrickletVoltageCurrent::FUNCTION_SET_DEBOUNCE_PERIOD = 20
 
.. rb:function:: BrickletVoltageCurrent#set_response_expected_all(response_expected) -> nil

 :param response_expected: bool

 Changes the response expected flag for all setter and callback configuration
 functions of this device at once.
 
.. rb:function:: BrickletVoltageCurrent#get_identity -> [str, str, str, [int, int, int], [int, int, int], int]


 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 :ref:`here <device_identifier>`.
 |device_identifier_constant|
 
 The returned array has the values ``uid``, ``connected_uid``, ``position``, ``hardware_version``, ``firmware_version`` and ``device_identifier``.

.. _voltage_current_bricklet_ruby_callbacks:

Callbacks
^^^^^^^^^

Callbacks can be registered to receive time critical or recurring data from
the device. The registration is done with the
:rb:func:`#register_callback <BrickletVoltageCurrent#register_callback>` function of
the device object. The first parameter is the callback ID and the second
parameter is a block:

.. code-block:: ruby

    voltage_current.register_callback BrickletVoltageCurrent::CALLBACK_EXAMPLE, do |param|
      puts "#{param}"
    end

The available constants with inherent number and type of parameters 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.

 :param current: int


 This callback is triggered periodically with the period that is set by
 :rb:func:`#set_current_callback_period <BrickletVoltageCurrent#set_current_callback_period>`. The parameter is the current of the

 last triggering.
 
.. rb:attribute:: BrickletVoltageCurrent::CALLBACK_CURRENT_REACHED

 :param current: int


 This callback is triggered when the threshold as set by
 :rb:func:`#set_current_callback_threshold <BrickletVoltageCurrent#set_current_callback_threshold>` is reached.
 The parameter is the current of the sensor.
 
 If the threshold keeps being reached, the callback is triggered periodically
 with the period as set by :rb:func:`#set_debounce_period <BrickletVoltageCurrent#set_debounce_period>`.
 
.. rb:attribute:: BrickletVoltageCurrent::CALLBACK_VOLTAGE_REACHED

 :param voltage: int


 This callback is triggered when the threshold as set by
 :rb:func:`#set_voltage_callback_threshold <BrickletVoltageCurrent#set_voltage_callback_threshold>` is reached.
 The parameter is the voltage of the sensor.
 
 If the threshold keeps being reached, the callback is triggered periodically
 with the period as set by :rb:func:`#set_debounce_period <BrickletVoltageCurrent#set_debounce_period>`.

.. _voltage_current_bricklet_ruby_constants:

Constants
^^^^^^^^^

.. rb:attribute:: BrickletVoltageCurrent::DEVICE_IDENTIFIER

 This constant is used to identify a Voltage/Current Bricklet.

 The :rb:func:`#get_identity() <BrickletVoltageCurrent#get_identity>` function and the
 :rb:attr:`::CALLBACK_ENUMERATE <IPConnection::CALLBACK_ENUMERATE>`
 callback of the IP Connection have a ``device_identifier`` parameter to specify
 the Brick's or Bricklet's type.
