    Hello forum members,

    I'm very happy with LIBREELEC, but currently, but I have one issue with it, I'm not able to solve.

    My HD44780 VFD just shows junk when using LIBREELEC.

    I bought a Noritake VFD GU140X32F. It can by used with serial or parallel interface and it's HD44780 compatible. I use it with an level shifter (3.3V-5V) and an converter (i2c - parallel).

    It tested the the function of the VFD with an Raspberry 4B and raspbian (current version). It works fine. (small python script to display some text to the lines) So, I assume, the wiring is okay.

    Using the current version of LIBREELEC (the stable one, of course) is just displaying some wired characters (blancs, rectangles and some "inverted question marks"). I tried it with the same Raspberry 4B and an ODROID C2. Both show the same output.

    Of course, I installed and configured the two addons (LCDproc + XBMC-LCDproc) in LIBREEELC. The I2C-port and the device name are checked.

    For my boot.ini (RP4) I added:

    dtparam=i2c1=on

    My LCDd.conf is:

    [server]

    DriverPath=/storage/.kodi/addons/http://service.lcdd/lib/lcdproc/

    Driver=hd44780

    Bind=127.0.0.1

    Port=13666

    [hd44780]

    ConnectionType=i2c

    Port=0x27

    Device=/dev/i2c-1

    Speed=0

    Keypad=no

    OutputPort=no

    Size=20x4

    CharMap=hd44780_default

    DelayBus=true

    KeyMatrix_4_1=Enter

    KeyMatrix_4_2=Up

    KeyMatrix_4_3=Down

    KeyMatrix_4_4=Escape


    Has anyone some suggestions to become successful?

    Thanks in advance,

    Joeker
