Basic Functions¶

class BrickletAnalogInV2(string uid, IPConnection ipcon)¶

Parameters:	uid – Type: string ipcon – Type: IPConnection
Returns:	analogInV2 – Type: BrickletAnalogInV2

Creates an object with the unique device ID uid:

BrickletAnalogInV2 analogInV2 = new BrickletAnalogInV2("YOUR_DEVICE_UID", ipcon);

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

int BrickletAnalogInV2.GetVoltage()¶

Returns:	voltage – Type: int, Unit: 1 mV, Range: [0 to 42000]

Returns the measured voltage. The resolution is approximately 10mV.

If you want to get the voltage periodically, it is recommended to use the VoltageCallback callback and set the period with SetVoltageCallbackPeriod().

Advanced Functions¶

int BrickletAnalogInV2.GetAnalogValue()¶

Returns:	value – Type: int, Range: [0 to 212 - 1]

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 AnalogValueCallback callback and set the period with SetAnalogValueCallbackPeriod().

void BrickletAnalogInV2.SetMovingAverage(byte average)¶

Parameters:	average – Type: byte, Range: [1 to 50], Default: 50

Sets the length of a moving averaging for the voltage.

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

byte BrickletAnalogInV2.GetMovingAverage()¶

Returns:	average – Type: byte, Range: [1 to 50], Default: 50

Returns the length of the moving average as set by SetMovingAverage().

void BrickletAnalogInV2.GetIdentity(out string uid, out string connectedUid, out char position, out byte[] hardwareVersion, out byte[] firmwareVersion, out int deviceIdentifier)¶

Output Parameters:

uid – Type: string, Length: up to 8 connectedUid – Type: string, Length: up to 8 position – Type: char, Range: ['a' to 'h', 'z'] hardwareVersion – Type: byte[], Length: 3 0: major – Type: byte, Range: [0 to 255] 1: minor – Type: byte, Range: [0 to 255] 2: revision – Type: byte, Range: [0 to 255] firmwareVersion – Type: byte[], Length: 3 0: major – Type: byte, Range: [0 to 255] 1: minor – Type: byte, Range: [0 to 255] 2: revision – Type: byte, Range: [0 to 255] deviceIdentifier – Type: int, Range: [0 to 216 - 1]

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 Isolator Bricklet is always at position 'z'.

The device identifier numbers can be found here. There is also a constant for the device identifier of this Bricklet.

Callbacks¶

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done by appending your callback handler to the corresponding event:

void MyCallback(BrickletAnalogInV2 sender, int value)
{
    System.Console.WriteLine("Value: " + value);
}

analogInV2.ExampleCallback += MyCallback;

The available events are described below.

event BrickletAnalogInV2.VoltageCallback(BrickletAnalogInV2 sender, int voltage)¶

Callback Parameters:	sender – Type: BrickletAnalogInV2 voltage – Type: int, Unit: 1 mV, Range: [0 to 42000]

This callback is triggered periodically with the period that is set by SetVoltageCallbackPeriod(). The parameter is the voltage of the sensor.

Der VoltageCallback callback is only triggered if the voltage has changed since the last triggering.

event BrickletAnalogInV2.AnalogValueCallback(BrickletAnalogInV2 sender, int value)¶

Callback Parameters:	sender – Type: BrickletAnalogInV2 value – Type: int, Range: [0 to 212 - 1]

This callback is triggered periodically with the period that is set by SetAnalogValueCallbackPeriod(). The parameter is the analog value of the sensor.

The AnalogValueCallback callback is only triggered if the voltage has changed since the last triggering.

event BrickletAnalogInV2.VoltageReachedCallback(BrickletAnalogInV2 sender, int voltage)¶

Callback Parameters:	sender – Type: BrickletAnalogInV2 voltage – Type: int, Unit: 1 mV, Range: [0 to 42000]

This callback is triggered when the threshold as set by SetVoltageCallbackThreshold() 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 SetDebouncePeriod().

event BrickletAnalogInV2.AnalogValueReachedCallback(BrickletAnalogInV2 sender, int value)¶

Callback Parameters:	sender – Type: BrickletAnalogInV2 value – Type: int, Range: [0 to 212 - 1]

This callback is triggered when the threshold as set by SetAnalogValueCallbackThreshold() 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 SetDebouncePeriod().

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.

byte[] BrickletAnalogInV2.GetAPIVersion()¶

Output Parameters:	apiVersion – Type: byte[], Length: 3 0: major – Type: byte, Range: [0 to 255] 1: minor – Type: byte, Range: [0 to 255] 2: revision – Type: byte, 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.

bool BrickletAnalogInV2.GetResponseExpected(byte functionId)¶

Parameters:	functionId – Type: byte, Range: See constants
Returns:	responseExpected – Type: bool

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:

• BrickletAnalogInV2.FUNCTION_SET_VOLTAGE_CALLBACK_PERIOD = 3
• BrickletAnalogInV2.FUNCTION_SET_ANALOG_VALUE_CALLBACK_PERIOD = 5
• BrickletAnalogInV2.FUNCTION_SET_VOLTAGE_CALLBACK_THRESHOLD = 7
• BrickletAnalogInV2.FUNCTION_SET_ANALOG_VALUE_CALLBACK_THRESHOLD = 9
• BrickletAnalogInV2.FUNCTION_SET_DEBOUNCE_PERIOD = 11
• BrickletAnalogInV2.FUNCTION_SET_MOVING_AVERAGE = 13

void BrickletAnalogInV2.SetResponseExpected(byte functionId, bool responseExpected)¶

Parameters:	functionId – Type: byte, Range: See constants responseExpected – Type: 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.

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:

• BrickletAnalogInV2.FUNCTION_SET_VOLTAGE_CALLBACK_PERIOD = 3
• BrickletAnalogInV2.FUNCTION_SET_ANALOG_VALUE_CALLBACK_PERIOD = 5
• BrickletAnalogInV2.FUNCTION_SET_VOLTAGE_CALLBACK_THRESHOLD = 7
• BrickletAnalogInV2.FUNCTION_SET_ANALOG_VALUE_CALLBACK_THRESHOLD = 9
• BrickletAnalogInV2.FUNCTION_SET_DEBOUNCE_PERIOD = 11
• BrickletAnalogInV2.FUNCTION_SET_MOVING_AVERAGE = 13

void BrickletAnalogInV2.SetResponseExpectedAll(bool responseExpected)¶

Parameters:	responseExpected – Type: bool

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

Constants¶

int BrickletAnalogInV2.DEVICE_IDENTIFIER¶

This constant is used to identify a 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 BrickletAnalogInV2.DEVICE_DISPLAY_NAME¶

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