    • Constructor Detail

      • BrickletLCD16x2

        public BrickletLCD16x2​(java.lang.String uid,
                               IPConnection ipcon)
        Creates an object with the unique device ID \c uid. and adds it to the IP Connection \c ipcon.
    • Method Detail

      • writeLine

        public void writeLine​(short line,
                              short position,
                              java.lang.String text)
                       throws TinkerforgeException
        Writes text to a specific line with a specific position. The text can have a maximum of 16 characters. For example: (0, 5, "Hello") will write *Hello* in the middle of the first line of the display. The display uses a special charset that includes all ASCII characters except backslash and tilde. The LCD charset also includes several other non-ASCII characters, see the `charset specification <https://github.com/Tinkerforge/lcd-16x2-bricklet/raw/master/datasheets/standard_charset.pdf>`__ for details. The Unicode example above shows how to specify non-ASCII characters and how to translate from Unicode to the LCD charset.
        Throws:
        TinkerforgeException
      • setConfig

        public void setConfig​(boolean cursor,
                              boolean blinking)
                       throws TinkerforgeException
        Configures if the cursor (shown as "_") should be visible and if it should be blinking (shown as a blinking block). The cursor position is one character behind the the last text written with writeLine(short, short, String).
        Throws:
        TinkerforgeException
      • setCustomCharacter

        public void setCustomCharacter​(short index,
                                       short[] character)
                                throws TinkerforgeException
        The LCD 16x2 Bricklet can store up to 8 custom characters. The characters consist of 5x8 pixels and can be addressed with the index 0-7. To describe the pixels, the first 5 bits of 8 bytes are used. For example, to make a custom character "H", you should transfer the following: * ``character[0] = 0b00010001`` (decimal value 17) * ``character[1] = 0b00010001`` (decimal value 17) * ``character[2] = 0b00010001`` (decimal value 17) * ``character[3] = 0b00011111`` (decimal value 31) * ``character[4] = 0b00010001`` (decimal value 17) * ``character[5] = 0b00010001`` (decimal value 17) * ``character[6] = 0b00010001`` (decimal value 17) * ``character[7] = 0b00000000`` (decimal value 0) The characters can later be written with writeLine(short, short, String) by using the characters with the byte representation 8 ("\\x08" or "\\u0008") to 15 ("\\x0F" or "\\u000F"). You can play around with the custom characters in Brick Viewer since version 2.0.1. Custom characters are stored by the LCD in RAM, so they have to be set after each startup. .. versionadded:: 2.0.1$nbsp;(Plugin)

      • 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|
