LCDproc problem

  • will need support added in our linux-amlogic kernel and support in the device tree before you can use it.


    What exactly are you referring to? I simply think that my config is wrong somehow. Why should something be added to device tree? I doubt the display was ever integrated into device tree on 7.0.2 builds (where it worked just fine). Is the kernel different between Krypton and Jarvis LibreELEC?
    Perhaps I misunderstand your reply?

    yes, the kernel is a completely different version. It is most likely missing some bits that are needed. I only just added SPI support for the odriod C2

  • thanks for your reply.I have Installed the addon & configure it but it wont work , lcd is connected by parallel port is possible to get this working on libreelec 64 bit (Generic) i have had it working under windows. when i run the script manually using ( /storage/.kodi/addons/service.lcdd/bin/lcdd.start ) i get this

  • Hi, I updated my RPi3 from LibreELEC 006 to 009. My LCD stopped working. Maybe I have to do something with my config files. Is here someone to guide me step by step what I should do to solve the problem? (I have installed LCDproc from LibreELEC repo and set Driver correctly)

  • Hi,


    when i try to start lcdd for my hd44780 connected via gpio on my rpi 3, i got the message
    "check_board_rev: This board is not recognized as a Raspberry Pi"
    Currently i've version 8.0.91 installed, but i've tried different versions with out success.


    can anybody help me to get my display running at my pi 3?

  • I have submitted a pull request to update the addon to the latest upstream commit, which among other things fixes hd44780 gpio issues.
    It should be available in the LibreELEC repository shortly.
    I can not test it, since I have no corresponding hardware.


    Use the settings of the addon (add-ons/my add-ons/service/LCDProc) to configure.
    Configuration files are in /storage/.kodi/userdata/addon_data/service.lcdd, acessible via ssh and smb.


    To view the log in ssh: journalctl -u service.lcdd

    and as it looks it does not work!



  • You are running on RPi (not on RPi2/3), right? If so, try ConnectionType=rpi, as suggested here LCD-Display HD44780 20×4 unter Openelec und Kodi(XBMC) an der Raspberry Pi – Michael Diesterhöft

  • i've installed this update (v.8.1.101) but no change.

    Code
    1. screenlist_init()
    2. driver_load(name="hd44780", filename="/storage/.kodi/addons/service.lcdd/lib/lcdproc/hd44780.so")
    3. HD44780: using ConnectionType: raspberrypi
    4. hd44780: Using hd44780_default charmap
    5. check_board_rev: This board is not recognized as a Raspberry Pi!
    6. Driver [hd44780] init failed, return code -1


    if i look into the driver dir (/storage/.kodi/addons/service.lcdd/lib/lcdproc/) the hd44780.so was updated and now it has 107336 bytes.


    any ideas ?

  • I have found some time, to look into lcdd addon and its dependencies:



    libugpio
    A builded and installed linux is not neccessarry to build libugpio. Libugpio deals direct with the sysfs gpio interface and no kernel functions are used.
    I think we can safely remove linux form libugpio package.mk.
    Has someone tested the hd44780 gpio driver from lcdd?


    lcdd
    Sofar if you build lcdd by hand in a clean environment (make clean, scripts/create_addon lcdd), lirc is not builded before and configure gives a warning

    Code
    1. checking for main in -llirc_client... no
    2. configure: WARNING: The lirc driver needs the lirc client library


    When lirc is set as dependency or it is simple installed by another package, lcdd fails to build.

    Code
    1. In file included from /home/michael/workspace/LibreELEC.tv/build.LibreELEC-imx6.arm-8.0-devel/toolchain/armv7a-libreelec-linux-gnueabi/sysroot/usr/include/lirc/lirc_client.h:124:0,
    2.                  from /home/michael/workspace/LibreELEC.tv/build.LibreELEC-imx6.arm-8.0-devel/lcdd-c05a7de/server/drivers/lircin.c:39:
    3. /home/michael/workspace/LibreELEC.tv/build.LibreELEC-imx6.arm-8.0-devel/toolchain/armv7a-libreelec-linux-gnueabi/sysroot/usr/include/lirc/curl_poll.h:36:29: error: array type has incomplete element type 'struct pollfd'
    4.  int curl_poll(struct pollfd ufds, unsigned int nfds, int timeout_ms);


    vpeter had give a workaround for this: thread-3793-post-28178.html#pid28178


    Is lirc needed as a dependency for lcdd?
