FUNCTION_GET_IDENTITY

This constant is used with the get_response_expected(), set_response_expected() and set_response_expected_all() subroutines.

FUNCTIONS

new()

Creates an object with the unique device ID *uid* and adds it to the IP Connection *ipcon*.

get_voltage()

Returns the measured voltage. The value is in mV and between 0V and 42V. The resolution is approximately 10mV.

If you want to get the voltage periodically, it is recommended to use the callback :func:`Voltage` and set the period with :func:`SetVoltageCallbackPeriod`.

get_analog_value()

Returns the value as read by a 12-bit analog-to-digital converter. The value is between 0 and 4095.

If you want the analog value periodically, it is recommended to use the callback :func:`AnalogValue` and set the period with :func:`SetAnalogValueCallbackPeriod`.

set_voltage_callback_period()

Sets the period in ms with which the :func:`Voltage` callback is triggered periodically. A value of 0 turns the callback off.

:func:`Voltage` is only triggered if the voltage has changed since the last triggering.

The default value is 0.

get_voltage_callback_period()

Returns the period as set by :func:`SetVoltageCallbackPeriod`.

set_analog_value_callback_period()

Sets the period in ms with which the :func:`AnalogValue` callback is triggered periodically. A value of 0 turns the callback off.

:func:`AnalogValue` is only triggered if the analog value has changed since the last triggering.

The default value is 0.

get_analog_value_callback_period()

Returns the period as set by :func:`SetAnalogValueCallbackPeriod`.

set_voltage_callback_threshold()

Sets the thresholds for the :func:`VoltageReached` callback.

The following options are possible:

.. csv-table:: :header: "Option", "Description" :widths: 10, 100

 "'x'",    "Callback is turned off"
 "'o'",    "Callback is triggered when the voltage is *outside* the min and max values"
 "'i'",    "Callback is triggered when the voltage is *inside* the min and max values"
 "'<'",    "Callback is triggered when the voltage is smaller than the min value (max is ignored)"
 "'>'",    "Callback is triggered when the voltage is greater than the min value (max is ignored)"

The default value is ('x', 0, 0).

get_voltage_callback_threshold()

Returns the threshold as set by :func:`SetVoltageCallbackThreshold`.

set_analog_value_callback_threshold()

Sets the thresholds for the :func:`AnalogValueReached` callback.

The following options are possible:

.. csv-table:: :header: "Option", "Description" :widths: 10, 100

 "'x'",    "Callback is turned off"
 "'o'",    "Callback is triggered when the analog value is *outside* the min and max values"
 "'i'",    "Callback is triggered when the analog value is *inside* the min and max values"
 "'<'",    "Callback is triggered when the analog value is smaller than the min value (max is ignored)"
 "'>'",    "Callback is triggered when the analog value is greater than the min value (max is ignored)"

The default value is ('x', 0, 0).

get_analog_value_callback_threshold()

Returns the threshold as set by :func:`SetAnalogValueCallbackThreshold`.

set_debounce_period()

Sets the period in ms with which the threshold callbacks

* :func:`VoltageReached`, * :func:`AnalogValueReached`

are triggered, if the thresholds

* :func:`SetVoltageCallbackThreshold`, * :func:`SetAnalogValueCallbackThreshold`

keep being reached.

The default value is 100.

get_debounce_period()

Returns the debounce period as set by :func:`SetDebouncePeriod`.

set_moving_average()

Sets the length of a `moving averaging <https://en.wikipedia.org/wiki/Moving_average>`__ for the moisture value.

Setting the length to 1 will turn the averaging off. With less averaging, there is more noise on the data.

The range for the averaging is 1-50.

The default value is 50.

get_moving_average()

Returns the length of the moving average as set by :func:`SetMovingAverage`.

get_identity()

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|
