RPi4 + Kodi + Ws2812B and no ambilight.

    Hello all,


    I have tried many other ways, but after many failed tries, I have decided to write here.


    I am using Raspberry Pi 4 (Raspbian OS Bullseye), and I want to have ambient light while I am watching IPTV over Kodi v19 (Matrix). I also use WS2812B LED Strip to obtain ambient light. HyperHDR is the application that I hope to work. I have tried this tutorial: https://www.raspberrypi.com/tu…y-pi-tv-ambient-lighting/


    My setup has 2 different PSU.

    - 1 for RPi4

    - 1 for Ws2812B LED Strip.

    LED's ground was connected to RPi4 GND pin, near to GPIO 18.


    I have tried to use with Video Capture device. The ambient light has worked if Kodi doesn't play a video/iptv stream/youtube video.


    The option "Instance Screen Capture" made me think I could use the system without a video capture device. However, LEDs are not active when I watch tv over Kodi.


    Many people use HyperHDR or Hyperion here, and I believe too many people are pro about these issues. I need help, and I am unsure what I should provide here to get help.

    Thanks in advance; I have tried to explain my problem step by step. Please let me know if you need further information.



    Best wishes!

    hey!



    you need to GND everything into common ground.


    also called V- / GND / common / - or 0volt



    so you connect at least two GND pins on the Raspi, and connect them to the V- PSU1 ( Raspi)

    then connect the Ledstrip GND to V- PSU2 (ledstrip)

    then connect the PSU1 and PSU2 ( must be both 5 V voltage for this to work) together by bridging V- together.




    now you made a common ground.

    so from this point on the GND issue can no longer be there.

    then i have to note; HyperHDR is a separate fork of dev. Awawa and not supported ( officially) on this forum.


    may i suggest that you first try the normal Hyperion.NG ( Hyperbian 2.013) that's a ready to go image you can deploy on the Raspi.


    second: for running WS281X PWM ledcontroller you need on Hyperbian ROOT acces;

    Code
    sudo updateHyperionUser -u root 

    enable this after installation of Hyperbian 2.013 on the terminal and reboot.



    then in terminal:

    Code
    sudo nano config.txt


    add value or change into:

    Code
    dtparam=audio=off 

    CTRL+O and CTRL+X to save config, then reboot again

    reboot in terminal:

    Code
    sudo reboot

    Hello!

    Thank you for your quick reply. Actually, I think I don't have gnd issue. It is working well and both psu are common grounded.



    Black wires represents ground (GND) and both of them 5 volts (5 volt 10 amp for LED Strip; 5 volts 2.5 Amp. for RPi4 -Original PSU)


    If you think there is still a problem may i request a basic draw how to do that?


    Thank you for your understanding. I wasn't aware of here is not support that fork. however, I have various other applications on my RPi4, like node-red, HAP-Node-JS smart home, webmin etc. Therefore, I don't want to setup an operating system like application. Is there any version that I can use with Raspbian OS together with my other applications?

    If yes, I would like to apply with a tutorial.


    Best wishes! Thank you.
