Basic Functions¶

class BrickletLCD128x64(String uid, IPConnection ipcon)¶

Parameters:	uid – Type: String ipcon – Type: IPConnection
Returns:	lcd128x64 – Type: BrickletLCD128x64

Creates an object with the unique device ID uid:

BrickletLCD128x64 lcd128x64 = new BrickletLCD128x64("YOUR_DEVICE_UID", ipcon);

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

void BrickletLCD128x64.writePixels(int xStart, int yStart, int xEnd, int yEnd, boolean[] pixels)¶

Parameters:	xStart – Type: int, Range: [0 to 127] yStart – Type: int, Range: [0 to 63] xEnd – Type: int, Range: [0 to 127] yEnd – Type: int, Range: [0 to 63] pixels – Type: boolean[], Length: variable

Writes pixels to the specified window.

The pixels are written into the window line by line top to bottom and each line is written from left to right.

If automatic draw is enabled (default) the pixels are directly written to the screen. Only pixels that have actually changed are updated on the screen, the rest stays the same.

If automatic draw is disabled the pixels are written to an internal buffer and the buffer is transferred to the display only after drawBufferedFrame() is called. This can be used to avoid flicker when drawing a complex frame in multiple steps.

Automatic draw can be configured with the setDisplayConfiguration() function.

boolean[] BrickletLCD128x64.readPixels(int xStart, int yStart, int xEnd, int yEnd)¶

Parameters:	xStart – Type: int, Range: [0 to 127] yStart – Type: int, Range: [0 to 63] xEnd – Type: int, Range: [0 to 127] yEnd – Type: int, Range: [0 to 63]
Returns:	pixels – Type: boolean[], Length: variable

Reads pixels from the specified window.

The pixels are read from the window line by line top to bottom and each line is read from left to right.

If automatic draw is enabled (default) the pixels that are read are always the same that are shown on the display.

If automatic draw is disabled the pixels are read from the internal buffer (see drawBufferedFrame()).

Automatic draw can be configured with the setDisplayConfiguration() function.

void BrickletLCD128x64.clearDisplay()¶

Clears the complete content of the display.

If automatic draw is enabled (default) the pixels are directly cleared.

If automatic draw is disabled the the internal buffer is cleared and the buffer is transferred to the display only after drawBufferedFrame() is called. This can be used to avoid flicker when drawing a complex frame in multiple steps.

Automatic draw can be configured with the setDisplayConfiguration() function.

void BrickletLCD128x64.writeLine(int line, int position, String text)¶

Parameters:	line – Type: int, Range: [0 to 7] position – Type: int, Range: [0 to 21] text – Type: String, Length: up to 22

Writes text to a specific line with a specific position.

For example: (1, 10, "Hello") will write Hello in the middle of the second line of the display.

The display uses a special 5x7 pixel charset. You can view the characters of the charset in Brick Viewer.

If automatic draw is enabled (default) the text is directly written to the screen. Only pixels that have actually changed are updated on the screen, the rest stays the same.

If automatic draw is disabled the text is written to an internal buffer and the buffer is transferred to the display only after drawBufferedFrame() is called. This can be used to avoid flicker when drawing a complex frame in multiple steps.

Automatic draw can be configured with the setDisplayConfiguration() function.

This function is a 1:1 replacement for the function with the same name in the LCD 20x4 Bricklet. You can draw text at a specific pixel position and with different font sizes with the drawText() function.

void BrickletLCD128x64.drawBufferedFrame(boolean forceCompleteRedraw)¶

Parameters:	forceCompleteRedraw – Type: boolean

Draws the currently buffered frame. Normally each call of writePixels() and writeLine() draws directly onto the display. If you turn automatic draw off (setDisplayConfiguration()), the data is written in an internal buffer and only transferred to the display by calling this function. This can be used to avoid flicker when drawing a complex frame in multiple steps.

Listeners¶

Listeners can be registered to receive time critical or recurring data from the device. The registration is done with add*Listener() functions of the device object.

The parameter is a listener class object, for example:

device.addExampleListener(new BrickletLCD128x64.ExampleListener() {
    public void property(int value) {
        System.out.println("Value: " + value);
    }
});

The available listener classes with inherent methods to be overwritten are described below. It is possible to add several listeners and to remove them with the corresponding remove*Listener() function.

class BrickletLCD128x64.TouchPositionListener()¶

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.

short[] BrickletLCD128x64.getAPIVersion()¶

Return Object:	apiVersion – Type: short[], Length: 3 0: major – Type: short, Range: [0 to 255] 1: minor – Type: short, Range: [0 to 255] 2: revision – Type: short, 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.

boolean BrickletLCD128x64.getResponseExpected(byte functionId)¶

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 listener 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:

• BrickletLCD128x64.FUNCTION_WRITE_PIXELS = 1

void BrickletLCD128x64.setResponseExpected(byte functionId, boolean responseExpected)¶

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 listener 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.

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.

int BrickletLCD128x64.setBootloaderMode(int mode)¶

Parameters:	mode – Type: int, Range: See constants
Returns:	status – Type: int, 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.

The following constants are available for this function:

For mode:

• BrickletLCD128x64.BOOTLOADER_MODE_BOOTLOADER = 0
• BrickletLCD128x64.BOOTLOADER_MODE_FIRMWARE = 1

void BrickletLCD128x64.setWriteFirmwarePointer(long pointer)¶

Parameters:	pointer – Type: long, Unit: 1 B, Range: [0 to 232 - 1]

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.

int BrickletLCD128x64.writeFirmware(int[] data)¶

Parameters:	data – Type: int[], Length: 64, Range: [0 to 255]
Returns:	status – Type: int, Range: [0 to 255]

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.

void BrickletLCD128x64.writeUID(long uid)¶

Parameters:	uid – Type: long, Range: [0 to 232 - 1]

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.

long BrickletLCD128x64.readUID()¶

Returns:	uid – Type: long, Range: [0 to 232 - 1]

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

Constants¶

int BrickletLCD128x64.DEVICE_IDENTIFIER¶

This constant is used to identify a LCD 128x64 Bricklet.

The getIdentity() function and the IPConnection.EnumerateListener listener of the IP Connection have a deviceIdentifier parameter to specify the Brick's or Bricklet's type.

String BrickletLCD128x64.DEVICE_DISPLAY_NAME¶

This constant represents the human readable name of a LCD 128x64 Bricklet.
