    Greetings. I finally got my setup running and starting to calibrate the color. I run the first color, white, as a jpeg or video. I have no white light. I have tweaked ever setting under the sun. What am I missing?

    My setup is:
    Raspberry pi 4 running Libreelec.
    293 WS2813 LEDs.
    Easycap USB capture stick plugged into a powered hub.
    20 amp power supply for the lights.
    5 amp power supply for the Rpi.
    Hyperion.ng.

    The log is here:

    Note that you will see in the log: (WARNING) SPI rate 10000000 outside recommended range (2106000 -> 3075000).
    If I set the SPI rate inside that recommended range, the lights don't come on at all.

    Here is the config file:

    Thanks in advance for any help.

    You can get your currant config by going to the web interface, under Configuration/General page,. There you can export the config file to your PC and then edit it if needed then import it back.

    Hope it helps.

    On a side note:
    Web interface of .NG is just Soooo easy. Thanks Dev's
    =)

    Try adding " spidev.bufsiz=32768 " to " /boot/cmdline.txt ". Also try adding " core_freq=250 " to " /boot/config.txt " if running on a Rpi3.

    That's the tips from the rpi_ws281x library git page ( https://github.com/jgarff/rpi_ws281x#spi ) Hyperion makes use of that library.

    Hope its of help.

    Could you use your hyperion with watching movies? Because there should be a signol drop.

    I added it to cmdline.txt. Same result, no white lights. I tried adding to config.txt but it wouldn't boot, probably because it's a Pi4.

    Both. Actually, I think I found the problem. I just realized I hooked up these 12 volt strips to a 5 volt power supply. When the 12 volt shows up in the mail I'll post if that fixed it.
