Constants
- CALLBACK_ANALOG_VALUE
This callback is triggered periodically with the period that is set by
BrickletAnalogInV2#set_analog_value_callback_period
. The parameter is the analog value of the sensor.The
CALLBACK_ANALOG_VALUE
callback is only triggered if the voltage has changed since the last triggering.- CALLBACK_ANALOG_VALUE_REACHED
This callback is triggered when the threshold as set by
BrickletAnalogInV2#set_analog_value_callback_threshold
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
BrickletAnalogInV2#set_debounce_period
.- CALLBACK_VOLTAGE
This callback is triggered periodically with the period that is set by
BrickletAnalogInV2#set_voltage_callback_period
. The parameter is the voltage of the sensor.Der
CALLBACK_VOLTAGE
callback is only triggered if the voltage has changed since the last triggering.- CALLBACK_VOLTAGE_REACHED
This callback is triggered when the threshold as set by
BrickletAnalogInV2#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

Public Instance Methods
Returns the value as read by a 12-bit 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 BrickletAnalogInV2#set_analog_value_callback_period
.

.
# File lib/tinkerforge/bricklet_analog_in_v2.rb, line 228 def get_debounce_period check_validity send_request FUNCTION_GET_DEBOUNCE_PERIOD, [], '', 12, 'L' end
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', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an :ref:`Isolator Bricklet <isolator_bricklet>` is always at position 'z'.
The device identifier numbers can be found :ref:`here <device_identifier>`. |device_identifier_constant|

Returns the length of the moving average as set by BrickletAnalogInV2#set_moving_average
.
# File lib/tinkerforge/bricklet_analog_in_v2.rb, line 246 def get_moving_average check_validity send_request FUNCTION_GET_MOVING_AVERAGE, [], '', 9, 'C' end
Returns the measured voltage. The resolution is approximately 10mV.
If you want to get the voltage periodically, it is recommended to use the CALLBACK_VOLTAGE
callback and set the period with BrickletAnalogInV2#set_voltage_callback_period
.

Registers a callback with ID id
to the block block
.
# File lib/tinkerforge/bricklet_analog_in_v2.rb, line 267 def register_callback(id, &block) callback = block @registered_callbacks[id] = callback end
Sets the period with which the CALLBACK_ANALOG_VALUE
callback is triggered periodically. A value of 0 turns the callback off.
The CALLBACK_ANALOG_VALUE
callback is only triggered if the analog value has changed since the last triggering.

Sets the thresholds for the CALLBACK_ANALOG_VALUE_REACHED
callback.
The following options are possible:
"Option", "Description" "'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)"

Sets the period with which the threshold callbacks
are triggered, if the thresholds
keep being reached.

Sets the period with which the CALLBACK_VOLTAGE
callback is triggered periodically. A value of 0 turns the callback off.
The CALLBACK_VOLTAGE
callback is only triggered if the voltage has changed since the last triggering.

Sets the thresholds for the CALLBACK_VOLTAGE_REACHED
callback.
