How to use Nevra anybeam hat on raspberry pi 3B with Libreelec

  • Hi, I'm some days checking about it and I was not able to solve it :(


    Base on the instructions provide by developer of Nebra AnyBeam HAT, I have follow the next steps on config.txt


    Fill the following comments into the next line of No.53 line (# Additional
    overlays and parameters are documented / boot / overlays / README) in
    the “config.txt “as shown in the following figure
    dtoverlay=dpi24
    overscan_left=0
    overscan_right=0
    overscan_top=0
    overscan_bottom=0
    framebuffer_width=1280
    framebuffer_height=720
    enable_dpi_lcd=1
    display_default_lcd=1
    dpi_group=2
    dpi_mode=85
    dpi_output_format=0x070027


    PDF document with the instructions:

    AnyBeam/Nebra AnyBeam HAT User Guide.pdf at master · NebraLtd/AnyBeam · GitHub


    This works perfectly with Raspbian and Retropie but not with libreelec.


    I have Libreelec 9.0.2


    Does anybody knows why and what I should do?


    Thanks a lot.

  • Thanks for your help. I try again mode 2 and does not change anything.
    In Retropie I have it with mode 1 and is working.

  • Try output_format=5 or output_format=6 for RGB666,


    or output_format=2, output_format=3, output_format=4 for RGB565,


    or output_format=7 for RGB888,


    Read this GPIO pin table to find the right value. One of those values should be merged into the dpi_output_format value.


    Have you already tried display mode 1 (RGB888)?

  • I've never seen this device before, so I just guess it's a color space issue. Provide a log file to see what happens under the hood.

  • Thanks a lot, I'm checking all the information and as soon as I have the logs I will put them. I wrote also to the developer to know where could be the issue and if they have any solution.
