Method Detail
-
setLEDValuesLowLevel
public void setLEDValuesLowLevel(int index, int valueLength, int valueChunkOffset, int[] valueChunkData) throws TinkerforgeException
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 (seesetChipType(int)
) and a channel mapping (seesetChannelMapping(int)
) 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 (seesetFrameDuration(int)
). 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 theBrickletLEDStripV2.FrameStartedListener
listener. * Set all of the LED colors for next frame. * Wait for theBrickletLEDStripV2.FrameStartedListener
listener. * And so on. This approach ensures that you can change the LED colors with a fixed frame rate.- Throws:
TinkerforgeException
-
getLEDValuesLowLevel
public BrickletLEDStripV2.LEDValuesLowLevel getLEDValuesLowLevel(int index, int length) throws TinkerforgeException
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)).- Throws:
TinkerforgeException
-
setFrameDuration
public void setFrameDuration(int duration) throws TinkerforgeException
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 seesetLEDValues(int, int[])
. Default value: 100ms (10 frames per second).- Throws:
TinkerforgeException
-
getFrameDuration
public int getFrameDuration() throws TinkerforgeException
Returns the frame duration as set bysetFrameDuration(int)
.- Throws:
TinkerforgeException
-
getSupplyVoltage
public int getSupplyVoltage() throws TinkerforgeException
Returns the current supply voltage of the LEDs.- Throws:
TinkerforgeException
-
setClockFrequency
public void setClockFrequency(long frequency) throws TinkerforgeException
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 callinggetClockFrequency()
. 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.- Throws:
TinkerforgeException
-
getClockFrequency
public long getClockFrequency() throws TinkerforgeException
Returns the currently used clock frequency as set bysetClockFrequency(long)
.- Throws:
TinkerforgeException
-
setChipType
public void setChipType(int chip) throws TinkerforgeException
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.- Throws:
TinkerforgeException
-
getChipType
public int getChipType() throws TinkerforgeException
Returns the currently used chip type as set bysetChipType(int)
.- Throws:
TinkerforgeException
-
setChannelMapping
public void setChannelMapping(int mapping) throws TinkerforgeException
Sets the channel mapping for the connected LEDs. If the mapping has 4 colors, the functionsetLEDValues(int, int[])
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.- Throws:
TinkerforgeException
-
getChannelMapping
public int getChannelMapping() throws TinkerforgeException
Returns the currently used channel mapping as set bysetChannelMapping(int)
.- Throws:
TinkerforgeException
-
setFrameStartedCallbackConfiguration
public void setFrameStartedCallbackConfiguration(boolean enable) throws TinkerforgeException
Enables/disables theBrickletLEDStripV2.FrameStartedListener
listener.- Throws:
TinkerforgeException
-
getFrameStartedCallbackConfiguration
public boolean getFrameStartedCallbackConfiguration() throws TinkerforgeException
Returns the configuration as set bysetFrameStartedCallbackConfiguration(boolean)
.- Throws:
TinkerforgeException
-
getSPITFPErrorCount
public BrickletLEDStripV2.SPITFPErrorCount getSPITFPErrorCount() throws TinkerforgeException
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.- Throws:
TinkerforgeException
-
setBootloaderMode
public int setBootloaderMode(int mode) throws TinkerforgeException
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.- Throws:
TinkerforgeException
-
getBootloaderMode
public int getBootloaderMode() throws TinkerforgeException
Returns the current bootloader mode, seesetBootloaderMode(int)
.- Throws:
TinkerforgeException
-
setWriteFirmwarePointer
public void setWriteFirmwarePointer(long pointer) throws TinkerforgeException
Sets the firmware pointer forwriteFirmware(int[])
. 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.- Throws:
TinkerforgeException
-
writeFirmware
public int writeFirmware(int[] data) throws TinkerforgeException
Writes 64 Bytes of firmware at the position as written bysetWriteFirmwarePointer(long)
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.- Throws:
TinkerforgeException
-
setStatusLEDConfig
public void setStatusLEDConfig(int config) throws TinkerforgeException
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.- Throws:
TinkerforgeException
-
getStatusLEDConfig
public int getStatusLEDConfig() throws TinkerforgeException
Returns the configuration as set bysetStatusLEDConfig(int)
- Throws:
TinkerforgeException
-
getChipTemperature
public int getChipTemperature() throws TinkerforgeException
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.- Throws:
TinkerforgeException
-
reset
public void reset() throws TinkerforgeException
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!- Throws:
TinkerforgeException
-
writeUID
public void writeUID(long uid) throws TinkerforgeException
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.- Throws:
TinkerforgeException
-
readUID
public long readUID() throws TinkerforgeException
Returns the current UID as an integer. Encode as Base58 to get the usual string version.- Throws:
TinkerforgeException
-
getIdentity
public Device.Identity getIdentity() throws TinkerforgeException
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 :ref:`Isolator Bricklet <isolator_bricklet>` is always at position 'z'. The device identifier numbers can be found :ref:`here <device_identifier>`. |device_identifier_constant|- Specified by:
getIdentity
in classDevice
- Throws:
TinkerforgeException
-
setLEDValues
public void setLEDValues(int index, int[] value) throws TinkerforgeException
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 (seesetChipType(int)
) and a channel mapping (seesetChannelMapping(int)
) 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 (seesetFrameDuration(int)
). 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 theBrickletLEDStripV2.FrameStartedListener
listener. * Set all of the LED colors for next frame. * Wait for theBrickletLEDStripV2.FrameStartedListener
listener. * And so on. This approach ensures that you can change the LED colors with a fixed frame rate.- Throws:
