API

Since Visual Basic .NET does not support multiple return values directly, we use the ByRef keyword to return multiple values from a function.

All functions and procedures listed below are thread-safe.

Basic Functions

Class BrickletLEDStripV2(ByVal uid As String, ByVal ipcon As IPConnection)

Creates an object with the unique device ID uid:

Dim ledStripV2 As New BrickletLEDStripV2("YOUR_DEVICE_UID", ipcon)

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

Sub BrickletLEDStripV2.SetLEDValues(ByVal index As Integer, ByVal value() As Byte)
Parameters:
  • index – Type: Integer, Range: [0 to 6144]
  • value – Type: Byte Array, Length: variable, Range: [0 to 255]

Sets the RGB(W) values for the LEDs starting from index. You can set at most 2048 RGB values or 1536 RGBW values (6144 byte each).

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.

Function BrickletLEDStripV2.GetLEDValues(ByVal index As Integer, ByVal length As Integer) As Byte()
Parameters:
  • index – Type: Integer, Range: [0 to 6144]
  • length – Type: Integer, Range: [0 to 6144]
Returns:
  • value – Type: Byte Array, Length: variable, Range: [0 to 255]

Returns length RGB(W) values starting from the given index.

If the channel mapping has 3 colors, you will get the data in the sequence RGBRGBRGB... if the channel mapping has 4 colors you will get the data in the sequence RGBWRGBWRGBW... (assuming you start at an index divisible by 3 (RGB) or 4 (RGBW)).

Sub BrickletLEDStripV2.SetFrameDuration(ByVal duration As Integer)
Parameters:
  • duration – Type: Integer, Unit: 1 ms, Range: [0 to 216 - 1], Default: 100

Sets the frame duration.

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).

Function BrickletLEDStripV2.GetFrameDuration() As Integer
Returns:
  • duration – Type: Integer, Unit: 1 ms, Range: [0 to 216 - 1], Default: 100

Returns the frame duration as set by SetFrameDuration().

Function BrickletLEDStripV2.GetSupplyVoltage() As Integer
Returns:
  • voltage – Type: Integer, Unit: 1 mV, Range: [0 to 216 - 1]

Returns the current supply voltage of the LEDs.

Sub BrickletLEDStripV2.SetClockFrequency(ByVal frequency As Long)
Parameters:
  • frequency – Type: Long, Unit: 1 Hz, Range: [10000 to 2000000], Default: 1666666

Sets the frequency of the clock.

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.

Function BrickletLEDStripV2.GetClockFrequency() As Long
Returns:
  • frequency – Type: Long, Unit: 1 Hz, Range: [10000 to 2000000], Default: 1666666

Returns the currently used clock frequency as set by SetClockFrequency().

Sub BrickletLEDStripV2.SetChipType(ByVal chip As Integer)
Parameters:
  • chip – Type: Integer, Range: See constants, Default: 2801

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),
  • WS2813 / WS2815 (Chip Type = WS2812)
  • LPD8806 and
  • APA102 / DotStar.

The following constants are available for this function:

For chip:

  • BrickletLEDStripV2.CHIP_TYPE_WS2801 = 2801
  • BrickletLEDStripV2.CHIP_TYPE_WS2811 = 2811
  • BrickletLEDStripV2.CHIP_TYPE_WS2812 = 2812
  • BrickletLEDStripV2.CHIP_TYPE_LPD8806 = 8806
  • BrickletLEDStripV2.CHIP_TYPE_APA102 = 102
Function BrickletLEDStripV2.GetChipType() As Integer
Returns:
  • chip – Type: Integer, Range: See constants, Default: 2801

Returns the currently used chip type as set by SetChipType().

The following constants are available for this function:

For chip:

  • BrickletLEDStripV2.CHIP_TYPE_WS2801 = 2801
  • BrickletLEDStripV2.CHIP_TYPE_WS2811 = 2811
  • BrickletLEDStripV2.CHIP_TYPE_WS2812 = 2812
  • BrickletLEDStripV2.CHIP_TYPE_LPD8806 = 8806
  • BrickletLEDStripV2.CHIP_TYPE_APA102 = 102
Sub BrickletLEDStripV2.SetChannelMapping(ByVal mapping As Byte)
Parameters:
  • mapping – Type: Byte, Range: See constants, Default: 36

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 following constants are available for this function:

Advanced Functions

Sub BrickletLEDStripV2.GetSPITFPErrorCount(ByRef errorCountAckChecksum As Long, ByRef errorCountMessageChecksum As Long, ByRef errorCountFrame As Long, ByRef errorCountOverflow As Long)
Output Parameters:
  • errorCountAckChecksum – Type: Long, Range: [0 to 232 - 1]
  • errorCountMessageChecksum – Type: Long, Range: [0 to 232 - 1]
  • errorCountFrame – Type: Long, Range: [0 to 232 - 1]
  • errorCountOverflow – Type: Long, Range: [0 to 232 - 1]

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.

Sub BrickletLEDStripV2.SetStatusLEDConfig(ByVal config As Byte)
Parameters:
  • config – Type: Byte, Range: See constants, Default: 3

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:

For config:

  • BrickletLEDStripV2.STATUS_LED_CONFIG_OFF = 0
  • BrickletLEDStripV2.STATUS_LED_CONFIG_ON = 1
  • BrickletLEDStripV2.STATUS_LED_CONFIG_SHOW_HEARTBEAT = 2
  • BrickletLEDStripV2.STATUS_LED_CONFIG_SHOW_STATUS = 3
Function BrickletLEDStripV2.GetStatusLEDConfig() As Byte
Returns:
  • config – Type: Byte, Range: See constants, Default: 3

Returns the configuration as set by SetStatusLEDConfig()

The following constants are available for this function:

For config:

  • BrickletLEDStripV2.STATUS_LED_CONFIG_OFF = 0
  • BrickletLEDStripV2.STATUS_LED_CONFIG_ON = 1
  • BrickletLEDStripV2.STATUS_LED_CONFIG_SHOW_HEARTBEAT = 2
  • BrickletLEDStripV2.STATUS_LED_CONFIG_SHOW_STATUS = 3
Function BrickletLEDStripV2.GetChipTemperature() As Short
Returns:
  • temperature – Type: Short, Unit: 1 °C, Range: [-215 to 215 - 1]

Returns the temperature 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.

Sub BrickletLEDStripV2.Reset()

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!

Sub BrickletLEDStripV2.GetIdentity(ByRef uid As String, ByRef connectedUid As String, ByRef position As Char, ByRef hardwareVersion() As Byte, ByRef firmwareVersion() As Byte, ByRef deviceIdentifier As Integer)
Output Parameters:
  • uid – Type: String, Length: up to 8
  • connectedUid – Type: String, Length: up to 8
  • position – Type: Char, Range: ["a"C to "h"C, "z"C]
  • hardwareVersion – Type: Byte Array, 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 Array, 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: Integer, 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

Sub BrickletLEDStripV2.SetFrameStartedCallbackConfiguration(ByVal enable As Boolean)
Parameters:
  • enable – Type: Boolean, Default: true

Enables/disables the FrameStartedCallback callback.

Function BrickletLEDStripV2.GetFrameStartedCallbackConfiguration() As Boolean
Returns:
  • enable – Type: Boolean, Default: true

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 procedure to an callback property of the device object:

Sub MyCallback(ByVal sender As BrickletLEDStripV2, ByVal value As Short)
    Console.WriteLine("Value: {0}", value)
End Sub

AddHandler ledStripV2.ExampleCallback, AddressOf MyCallback

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(ByVal sender As BrickletLEDStripV2, ByVal length As Integer)
Callback Parameters:
  • sender – Type: BrickletLEDStripV2
  • length – Type: Integer, Range: [0 to 6144]

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().

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.

Function BrickletLEDStripV2.GetAPIVersion() As Byte()
Output Parameters:
  • apiVersion – Type: Byte Array, 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.

Function BrickletLEDStripV2.GetResponseExpected(ByVal functionId As Byte) As Boolean
Parameters:
  • functionId – Type: Byte, Range: See constants
Returns:
  • 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:

  • BrickletLEDStripV2.FUNCTION_SET_LED_VALUES = 1
  • BrickletLEDStripV2.FUNCTION_SET_FRAME_DURATION = 3
  • BrickletLEDStripV2.FUNCTION_SET_CLOCK_FREQUENCY = 7
  • BrickletLEDStripV2.FUNCTION_SET_CHIP_TYPE = 9
  • BrickletLEDStripV2.FUNCTION_SET_CHANNEL_MAPPING = 11
  • BrickletLEDStripV2.FUNCTION_SET_FRAME_STARTED_CALLBACK_CONFIGURATION = 13
  • BrickletLEDStripV2.FUNCTION_SET_WRITE_FIRMWARE_POINTER = 237
  • BrickletLEDStripV2.FUNCTION_SET_STATUS_LED_CONFIG = 239
  • BrickletLEDStripV2.FUNCTION_RESET = 243
  • BrickletLEDStripV2.FUNCTION_WRITE_UID = 248
Sub BrickletLEDStripV2.SetResponseExpected(ByVal functionId As Byte, ByVal responseExpected As Boolean)
Parameters:
  • 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:

  • BrickletLEDStripV2.FUNCTION_SET_LED_VALUES = 1
  • BrickletLEDStripV2.FUNCTION_SET_FRAME_DURATION = 3
  • BrickletLEDStripV2.FUNCTION_SET_CLOCK_FREQUENCY = 7
  • BrickletLEDStripV2.FUNCTION_SET_CHIP_TYPE = 9
  • BrickletLEDStripV2.FUNCTION_SET_CHANNEL_MAPPING = 11
  • BrickletLEDStripV2.FUNCTION_SET_FRAME_STARTED_CALLBACK_CONFIGURATION = 13
  • BrickletLEDStripV2.FUNCTION_SET_WRITE_FIRMWARE_POINTER = 237
  • BrickletLEDStripV2.FUNCTION_SET_STATUS_LED_CONFIG = 239
  • BrickletLEDStripV2.FUNCTION_RESET = 243
  • BrickletLEDStripV2.FUNCTION_WRITE_UID = 248
Sub BrickletLEDStripV2.SetResponseExpectedAll(ByVal responseExpected As Boolean)
Parameters:
  • responseExpected – Type: Boolean

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

Internal Functions

Internal functions are used for maintenance tasks such as flashing a new firmware of changing the UID of a Bricklet. These task should be performed using Brick Viewer instead of using the internal functions directly.

Function BrickletLEDStripV2.SetBootloaderMode(ByVal mode As Byte) As Byte
Parameters:
  • mode – Type: Byte, Range: See constants
Returns:
  • status – Type: Byte, Range: See constants

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.
