API

Generally, every method of the C# 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 C# does not support multiple return values directly, we use the out keyword to return multiple values from a method.

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

All methods listed below are thread-safe.

Basic Functions

class BrickletIndustrialDualAnalogIn(String uid, IPConnection ipcon)
Parameters:
  • uid – Type: String
  • ipcon – Type: IPConnection
Returns:
  • industrialDualAnalogIn – Type: BrickletIndustrialDualAnalogIn

Creates an object with the unique device ID uid:

BrickletIndustrialDualAnalogIn industrialDualAnalogIn = new BrickletIndustrialDualAnalogIn("YOUR_DEVICE_UID", ipcon);

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

int BrickletIndustrialDualAnalogIn.GetVoltage(byte channel)
Parameters:
  • channel – Type: byte, Range: [0 to 1]
Returns:
  • voltage – Type: int, Unit: 1 mV, Range: [-35000 to 35000]

Returns the voltage for the given channel.

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

The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). The Raspberry Pi HAT (Zero) Brick is always at position 'i' and the Bricklet connected to an Isolator Bricklet is always as position 'z'.

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

'<' 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 following constants are available for this function:

For option:

  • BrickletIndustrialDualAnalogIn.THRESHOLD_OPTION_OFF = 'x'
  • BrickletIndustrialDualAnalogIn.THRESHOLD_OPTION_OUTSIDE = 'o'
  • BrickletIndustrialDualAnalogIn.THRESHOLD_OPTION_INSIDE = 'i'

void BrickletIndustrialDualAnalogIn.SetDebouncePeriod(long debounce)
Parameters:
  • debounce – Type: long, Unit: 1 ms, Range: [0 to 232 - 1], Default: 100

Sets the period with which the threshold callback

is triggered, if the threshold

keeps being reached.

long BrickletIndustrialDualAnalogIn.GetDebouncePeriod()
Returns:
  • debounce – Type: long, Unit: 1 ms, Range: [0 to 232 - 1], Default: 100

Returns the debounce period as set by SetDebouncePeriod().

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

industrialDualAnalogIn.ExampleCallback += MyCallback;

The available events 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.

event BrickletIndustrialDualAnalogIn.VoltageCallback(BrickletIndustrialDualAnalogIn sender, byte channel, int voltage)
Callback Parameters:
  • sender – Type: BrickletIndustrialDualAnalogIn
  • channel – Type: byte, Range: [0 to 1]
  • voltage – Type: int, Unit: 1 mV, Range: [-35000 to 35000]

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

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

event BrickletIndustrialDualAnalogIn.VoltageReachedCallback(BrickletIndustrialDualAnalogIn sender, byte channel, int voltage)
Callback Parameters:
  • sender – Type: BrickletIndustrialDualAnalogIn
  • channel – Type: byte, Range: [0 to 1]
  • voltage – Type: int, Unit: 1 mV, Range: [-35000 to 35000]

This callback is triggered when the threshold as set by SetVoltageCallbackThreshold() is reached. The parameter is the voltage of the channel.

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[] BrickletIndustrialDualAnalogIn.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 BrickletIndustrialDualAnalogIn.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 send and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For functionId:

  • BrickletIndustrialDualAnalogIn.FUNCTION_SET_VOLTAGE_CALLBACK_PERIOD = 2
  • BrickletIndustrialDualAnalogIn.FUNCTION_SET_VOLTAGE_CALLBACK_THRESHOLD = 4
  • BrickletIndustrialDualAnalogIn.FUNCTION_SET_DEBOUNCE_PERIOD = 6
  • BrickletIndustrialDualAnalogIn.FUNCTION_SET_SAMPLE_RATE = 8
  • BrickletIndustrialDualAnalogIn.FUNCTION_SET_CALIBRATION = 10
void BrickletIndustrialDualAnalogIn.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 send and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For functionId:

  • BrickletIndustrialDualAnalogIn.FUNCTION_SET_VOLTAGE_CALLBACK_PERIOD = 2
  • BrickletIndustrialDualAnalogIn.FUNCTION_SET_VOLTAGE_CALLBACK_THRESHOLD = 4
  • BrickletIndustrialDualAnalogIn.FUNCTION_SET_DEBOUNCE_PERIOD = 6
  • BrickletIndustrialDualAnalogIn.FUNCTION_SET_SAMPLE_RATE = 8
  • BrickletIndustrialDualAnalogIn.FUNCTION_SET_CALIBRATION = 10
void BrickletIndustrialDualAnalogIn.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 BrickletIndustrialDualAnalogIn.DEVICE_IDENTIFIER

This constant is used to identify a Industrial Dual Analog In Bricklet.

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 BrickletIndustrialDualAnalogIn.DEVICE_DISPLAY_NAME

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