Basic Functions¶

BrickletTilt(uid, ipcon) → tilt¶

Input:	uid – Type: String ipcon – Type: .NET Refnum (IPConnection)
Output:	tilt – Type: .NET Refnum (BrickletTilt)

Creates an object with the unique device ID uid. This object can then be used after the IP Connection is connected.

BrickletTilt.GetTiltState() → state¶

Output:	state – Type: Byte, Range: See constants

Returns the current tilt state. The state can either be

• 0 = Closed: The ball in the tilt switch closes the circuit.
• 1 = Open: The ball in the tilt switch does not close the circuit.
• 2 = Closed Vibrating: The tilt switch is in motion (rapid change between open and close).

The following constants are available for this function:

For state:

• BrickletTilt.TILT_STATE_CLOSED = 0
• BrickletTilt.TILT_STATE_OPEN = 1
• BrickletTilt.TILT_STATE_CLOSED_VIBRATING = 2

Advanced Functions¶

BrickletTilt.GetIdentity() → uid, connectedUid, position, hardwareVersion, firmwareVersion, deviceIdentifier¶

Output:

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[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[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: Int32, 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.

Callback Configuration Functions¶

BrickletTilt.EnableTiltStateCallback()¶

Enables the TiltStateCallback callback.

BrickletTilt.DisableTiltStateCallback()¶

Disables the TiltStateCallback callback.

BrickletTilt.IsTiltStateCallbackEnabled() → enabled¶

Output:	enabled – Type: Boolean, Default: F

Returns true if the TiltStateCallback callback is enabled.

Callbacks¶

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done by assigning a function to a callback property of the device object. The available callback property and their type of parameters are described below.

event BrickletTilt.TiltStateCallback → sender, state¶

Callback Output:	sender – Type: .NET Refnum (BrickletTilt) state – Type: Byte, Range: See constants

This callback provides the current tilt state. It is called every time the state changes.

See GetTiltState() for a description of the states.

The following constants are available for this function:

For state:

• BrickletTilt.TILT_STATE_CLOSED = 0
• BrickletTilt.TILT_STATE_OPEN = 1
• BrickletTilt.TILT_STATE_CLOSED_VIBRATING = 2

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.

BrickletTilt.GetAPIVersion() → apiVersion¶

Output:	apiVersion – Type: Byte[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.

BrickletTilt.GetResponseExpected(functionId) → responseExpected¶

Input:	functionId – Type: Byte, Range: See constants
Output:	responseExpected – Type: Boolean

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:

• BrickletTilt.FUNCTION_ENABLE_TILT_STATE_CALLBACK = 2
• BrickletTilt.FUNCTION_DISABLE_TILT_STATE_CALLBACK = 3

BrickletTilt.SetResponseExpected(functionId, responseExpected)¶

Input:	functionId – Type: Byte, Range: See constants responseExpected – Type: Boolean

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:

• BrickletTilt.FUNCTION_ENABLE_TILT_STATE_CALLBACK = 2
• BrickletTilt.FUNCTION_DISABLE_TILT_STATE_CALLBACK = 3

BrickletTilt.SetResponseExpectedAll(responseExpected)¶

Input:	responseExpected – Type: Boolean

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

Constants¶

BrickletTilt.DEVICE_IDENTIFIER¶

This constant is used to identify a Tilt 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.

BrickletTilt.DEVICE_DISPLAY_NAME¶

This constant represents the human readable name of a Tilt Bricklet.
