LCD not working properly

    Hello everybody,

    I've bought a HD55780 20x4 LCD with I2C-interface (this one). It's connected to a Raspberry 3 by 4 wires (GPIO 3-6). I've installed Libreelec 7.0.3 and XBM LCDProc 2.6.0 Add-On and activated the HD44780-driver.

    I filled in /flash/config.txt via ssh:

    dtparam=i2c_arm=on

    …and also some informations in /storage/.config/LCDd.conf:

    The Problem is: When the Raspi is operating, the LCD's background-LED is flashing and only 2 of 4 lines are showing blocks, no letters. In the logfile (01_KODI.log) I found this:

    18:34:01 9.836284 T:1814033312 NOTICE: ### [XBMC LCDproc] - Empty driver information

    I've also tried out Raspbian (lite), which is mentioned in the LCD's manual above. The LCD works fine, but I would prefer Libreelec.

    So any ideas how to get the LCD working in Lireelec?

    Hi there,

    I've tried al little more (still HD55780 20x4 LCD with I2C-interface, connected to Raspy 3,GPIO 3-6:(

    Downloaded Libreelec v7.95.3 BETA for Raspi 2/3 (LibreELEC-RPi2.arm-7.95.3.img.gz, see tip in thread-3614-post-27722.html#pid27722),
    copied it to sd-card and started Libreelec 7.95 BETA on my Raspi3.

    Installed Add-On XMBC.LCDproc from Libreelec-repository and activated it.

    Edited LCDd.conf in terminal (via ssh):
    (…)


    (…)
        ## Hitachi HD44780 driver ##
    [hd44780]

    • ConnectionType=i2c
    • Port=0x27
    • Device=/dev/ic2-1


    (…)

    Saved changes and after reboot a notification appeared:
    "no connection to LCDProc" (in german: "XMBC LCDProc: Fehler beim Verbinden zu LCDProc!").

    LCD shows still 2 lines of blocks, constant backlight (no more flashing).

    KODI.log:
    (…)
          DEBUG: ### [XBMC LCDproc] - Open 127.0.0.1:13666
    ERROR: ### [XBMC LCDproc] - Connect: Caught exception, aborting.
    ERROR: ### [XBMC LCDproc] - Connect failed. Retry in 64 seconds.
    (…)

    So dis anybody get the LCD working?
