API

Generally, every method of the Mathematica 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 .NET/Link does not support multiple return values directly, we use the out keyword to return multiple values from a method. For further information about the out keyword in .NET/Link see the corresponding Mathematica .NET/Link documentation.

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

Basic Functions

BrickletLEDStripV2[uid, ipcon] → ledStripV2
Parameters:
  • uid -- String
  • ipcon -- NETObject[IPConnection]
Returns:
  • ledStripV2 -- NETObject[BrickletLEDStripV2]

Creates an object with the unique device ID uid:

ledStripV2=NETNew["Tinkerforge.BrickletLEDStripV2","YOUR_DEVICE_UID",ipcon]

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

The .NET runtime has built-in garbage collection that frees objects that are no longer in use by a program. But because Mathematica can not automatically tell when a Mathematica "program" doesn't use a .NET object anymore, this has to be done by the program. For this the ReleaseNETObject[] function is used in the examples.

For further information about object management in .NET/Link see the corresponding Mathematica .NET/Link documentation.

BrickletLEDStripV2@SetLEDValues[index, {value1, value2, ...}] → Null
Parameters:
  • index -- Integer
  • valuei -- Integer

Sets the RGB(W) values for the LEDs starting from index. You can set at most 2048 RGB values or 1536 RGBW values.

To make the colors show correctly you need to configure the chip type (see SetChipType[]) and a channel mapping (see SetChannelMapping[]) according to the connected LEDs.

If the channel mapping has 3 colors, you need to give the data in the sequence RGBRGBRGB... if the channel mapping has 4 colors you need to give data in the sequence RGBWRGBWRGBW...

The data is double buffered and the colors will be transfered to the LEDs when the next frame duration ends (see SetFrameDuration[]).

Generic approach:

  • Set the frame duration to a value that represents the number of frames per second you want to achieve.
  • Set all of the LED colors for one frame.
  • Wait for the FrameStartedCallback callback.
  • Set all of the LED colors for next frame.
  • Wait for the FrameStartedCallback callback.
  • And so on.

This approach ensures that you can change the LED colors with a fixed frame rate.

BrickletLEDStripV2@GetLEDValues[index, length] → {value1, value2, ...}
Parameters:
  • index -- Integer
  • length -- Integer
Returns:
  • valuei -- Integer

Returns the RGB(W) values as set by SetLEDValues[].

BrickletLEDStripV2@SetFrameDuration[duration] → Null
Parameters:
  • duration -- Integer

Sets the frame duration in ms.

Example: If you want to achieve 20 frames per second, you should set the frame duration to 50ms (50ms * 20 = 1 second).

For an explanation of the general approach see SetLEDValues[].

Default value: 100ms (10 frames per second).

BrickletLEDStripV2@GetFrameDuration[] → duration
Returns:
  • duration -- Integer

Returns the frame duration in ms as set by SetFrameDuration[].

BrickletLEDStripV2@GetSupplyVoltage[] → voltage
Returns:
  • voltage -- Integer

Returns the current supply voltage of the LEDs. The voltage is given in mV.

BrickletLEDStripV2@SetClockFrequency[frequency] → Null
Parameters:
  • frequency -- Integer

Sets the frequency of the clock in Hz. The range is 10000Hz (10kHz) up to 2000000Hz (2MHz).

The Bricklet will choose the nearest achievable frequency, which may be off by a few Hz. You can get the exact frequency that is used by calling GetClockFrequency[].

If you have problems with flickering LEDs, they may be bits flipping. You can fix this by either making the connection between the LEDs and the Bricklet shorter or by reducing the frequency.

With a decreasing frequency your maximum frames per second will decrease too.

The default value is 1.66MHz.

BrickletLEDStripV2@GetClockFrequency[] → frequency
Returns:
  • frequency -- Integer

Returns the currently used clock frequency as set by SetClockFrequency[].

BrickletLEDStripV2@SetChipType[chip] → Null
Parameters:
  • chip -- Integer

Sets the type of the LED driver chip. We currently support the chips

  • WS2801,
  • WS2811,
  • WS2812 / SK6812 / NeoPixel RGB,
  • SK6812RGBW / NeoPixel RGBW (Chip Type = WS2812),
  • LPD8806 and
  • APA102 / DotStar.

The default value is WS2801 (2801).

The following constants are available for this function:

  • BrickletLEDStripV2`CHIPUTYPEUWS2801 = 2801
  • BrickletLEDStripV2`CHIPUTYPEUWS2811 = 2811
  • BrickletLEDStripV2`CHIPUTYPEUWS2812 = 2812
  • BrickletLEDStripV2`CHIPUTYPEULPD8806 = 8806
  • BrickletLEDStripV2`CHIPUTYPEUAPA102 = 102
BrickletLEDStripV2@GetChipType[] → chip
Returns:
  • chip -- Integer

Returns the currently used chip type as set by SetChipType[].

The following constants are available for this function:

  • BrickletLEDStripV2`CHIPUTYPEUWS2801 = 2801
  • BrickletLEDStripV2`CHIPUTYPEUWS2811 = 2811
  • BrickletLEDStripV2`CHIPUTYPEUWS2812 = 2812
  • BrickletLEDStripV2`CHIPUTYPEULPD8806 = 8806
  • BrickletLEDStripV2`CHIPUTYPEUAPA102 = 102
BrickletLEDStripV2@SetChannelMapping[mapping] → Null
Parameters:
  • mapping -- Integer

Sets the channel mapping for the connected LEDs.

If the mapping has 4 colors, the function SetLEDValues[] expects 4 values per pixel and if the mapping has 3 colors it expects 3 values per pixel.

The function always expects the order RGB(W). The connected LED driver chips might have their 3 or 4 channels in a different order. For example, the WS2801 chips typically use BGR order, then WS2812 chips typically use GRB order and the APA102 chips typically use WBGR order.

The APA102 chips are special. They have three 8-bit channels for RGB and an additional 5-bit channel for the overall brightness of the RGB LED making them 4-channel chips. Internally the brightness channel is the first channel, therefore one of the Wxyz channel mappings should be used. Then the W channel controls the brightness.

The default value is BGR (36).

Advanced Functions

BrickletLEDStripV2@GetAPIVersion[] → {apiVersion1, apiVersion2, apiVersion3}
Returns:
  • apiVersioni -- Integer

Returns the version of the API definition (major, minor, revision) 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.

BrickletLEDStripV2@GetResponseExpected[functionId] → responseExpected
Parameters:
  • functionId -- Integer
Returns:
  • responseExpected -- True/False

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.

See SetResponseExpected[] for the list of function ID constants available for this function.

BrickletLEDStripV2@SetResponseExpected[functionId, responseExpected] → Null
Parameters:
  • functionId -- Integer
  • responseExpected -- True/False

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 function ID constants are available for this function:

  • BrickletLEDStripV2`FUNCTIONUSETULEDUVALUES = 1
  • BrickletLEDStripV2`FUNCTIONUSETUFRAMEUDURATION = 3
  • BrickletLEDStripV2`FUNCTIONUSETUCLOCKUFREQUENCY = 7
  • BrickletLEDStripV2`FUNCTIONUSETUCHIPUTYPE = 9

  • BrickletLEDStripV2`FUNCTIONUSETUSTATUSULEDUCONFIG = 239
  • BrickletLEDStripV2`FUNCTIONURESET = 243
  • BrickletLEDStripV2`FUNCTIONUWRITEUUID = 248
BrickletLEDStripV2@SetResponseExpectedAll[responseExpected] → Null
Parameters:
  • responseExpected -- True/False

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

BrickletLEDStripV2@GetSPITFPErrorCount[out errorCountAckChecksum, out errorCountMessageChecksum, out errorCountFrame, out errorCountOverflow] → Null
Parameters:
  • errorCountAckChecksum -- Integer
  • errorCountMessageChecksum -- Integer
  • errorCountFrame -- Integer
  • errorCountOverflow -- Integer

Returns the error count for the communication between Brick and Bricklet.

The errors are divided into

  • ACK checksum errors,
  • message checksum errors,
  • framing errors and
  • overflow errors.

The errors counts are for errors that occur on the Bricklet side. All Bricks have a similar function that returns the errors on the Brick side.

BrickletLEDStripV2@SetBootloaderMode[mode] → status
Parameters:
  • mode -- Integer
Returns:
  • status -- Integer

Sets the bootloader mode and returns the status after the requested mode change was instigated.

You can change from bootloader mode to firmware mode and vice versa. A change from bootloader mode to firmware mode will only take place if the entry function, device identifier and CRC are present and correct.

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

  • BrickletLEDStripV2`BOOTLOADERUMODEUFIRMWARE = 1
  • BrickletLEDStripV2`BOOTLOADERUMODEUBOOTLOADERUWAITUFORUREBOOT = 2
  • BrickletLEDStripV2`BOOTLOADERUMODEUFIRMWAREUWAITUFORUREBOOT = 3
  • BrickletLEDStripV2`BOOTLOADERUMODEUFIRMWAREUWAITUFORUERASEUANDUREBOOT = 4
BrickletLEDStripV2@SetWriteFirmwarePointer[pointer] → Null
Parameters:
  • pointer -- Integer

Sets the firmware pointer for WriteFirmware[]. The pointer has to be increased by chunks of size 64. The data is written to flash every 4 chunks (which equals to one page of size 256).

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

BrickletLEDStripV2@WriteFirmware[{data1, data2, ..., data64}] → status
Parameters:
  • datai -- Integer
Returns:
  • status -- Integer

Writes 64 Bytes of firmware at the position as written by SetWriteFirmwarePointer[] before. The firmware is written to flash every 4 chunks.

You can only write firmware in bootloader mode.

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

BrickletLEDStripV2@SetStatusLEDConfig[config] → Null
Parameters:
  • config -- Integer

Sets the status LED configuration. By default the LED shows communication traffic between Brick and Bricklet, it flickers once for every 10 received data packets.

You can also turn the LED permanently on/off or show a heartbeat.

If the Bricklet is in bootloader mode, the LED is will show heartbeat by default.

The following constants are available for this function:

  • BrickletLEDStripV2`STATUSULEDUCONFIGUOFF = 0
  • BrickletLEDStripV2`STATUSULEDUCONFIGUON = 1

  • BrickletLEDStripV2`STATUSULEDUCONFIGUSHOWUSTATUS = 3
BrickletLEDStripV2@GetChipTemperature[] → temperature
Returns:
  • temperature -- Integer

Returns the temperature in °C as measured inside the microcontroller. The value returned is not the ambient temperature!

The temperature is only proportional to the real temperature and it has bad accuracy. Practically it is only useful as an indicator for temperature changes.

BrickletLEDStripV2@Reset[] → Null

Calling this function will reset the Bricklet. All configurations will be lost.

After a reset you have to create new device objects, calling functions on the existing ones will result in undefined behavior!

BrickletLEDStripV2@WriteUID[uid] → Null
Parameters:
  • uid -- Integer

Writes a new UID into flash. If you want to set a new UID you have to decode the Base58 encoded UID string into an integer first.

We recommend that you use Brick Viewer to change the UID.

BrickletLEDStripV2@ReadUID[] → uid
Returns:
  • uid -- Integer

Returns the current UID as an integer. Encode as Base58 to get the usual string version.

BrickletLEDStripV2@GetIdentity[out uid, out connectedUid, out position, out {hardwareVersion1, hardwareVersion2, hardwareVersion3}, out {firmwareVersion1, firmwareVersion2, firmwareVersion3}, out deviceIdentifier] → Null
Parameters:
  • uid -- String
  • connectedUid -- String
  • position -- Integer
  • hardwareVersioni -- Integer
  • firmwareVersioni -- Integer
  • deviceIdentifier -- Integer

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 here. There is also a constant for the device identifier of this Bricklet.

Callback Configuration Functions

BrickletLEDStripV2@SetFrameStartedCallbackConfiguration[enable] → Null
Parameters:
  • enable -- True/False

Enables/disables the FrameStartedCallback callback.

By default the callback is enabled.

BrickletLEDStripV2@GetFrameStartedCallbackConfiguration[] → enable
Returns:
  • enable -- True/False

Returns the configuration as set by SetFrameStartedCallbackConfiguration[].

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:

MyCallback[sender_,value_]:=Print["Value: "<>ToString[value]]

AddEventHandler[ledStripV2@ExampleCallback,MyCallback]

For further information about event handling using .NET/Link see the corresponding Mathematica .NET/Link documentation.

The available callback property and their type of parameters 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 BrickletLEDStripV2@FrameStartedCallback[sender, length]
Parameters:
  • sender -- NETObject[BrickletLEDStripV2]
  • length -- Integer

This callback is triggered directly after a new frame render is started. The parameter is the number of LEDs in that frame.

You should send the data for the next frame directly after this callback was triggered.

For an explanation of the general approach see SetLEDValues[].

Constants

BrickletLEDStripV2`DEVICEUIDENTIFIER

This constant is used to identify a LED Strip Bricklet 2.0.

The GetIdentity[] function and the EnumerateCallback callback of the IP Connection have a deviceIdentifier parameter to specify the Brick's or Bricklet's type.

BrickletLEDStripV2`DEVICEDISPLAYNAME

This constant represents the human readable name of a LED Strip Bricklet 2.0.
