    Hello,

    I need help, I understand this topic is made a few times on the forum and I didn't wanted to make another topic of the same content but nothing works for me. It could be that I'm missing something.

    For a start I have only basic knowledge about raspberry and its OS. As you could see in the title this is Raspberry Pi 4 related.

    My hardware is:
    Raspberry Pi 4 4GB rev.1.2
    Switching Power Supply 5v 10A
    WS2812B Led Strip (400 LEDs)
    But for testing, I'm using small stripe cutoff with 8 LEDs on it.

    Connection:
    A connection is done the same as for Rpi 3b+.

    Negative (-) from the power supply is connected to negative on WS2812 strip and to pin 6 (GND) on Rpi. Positive (+) from the power supply is connected just to positive (5v+) on WS2812 strip. Data from WS2812 is connected to pin 12 (GPIO 18) on Rpi.

    OS:
    For OS I'm using newest Raspbian Booster (also tried newest LibreElec, ended up with same result and error)

    Hyperion:
    Tried both terminal-based installation and with HyperCon

    An error that I'm getting is:
    Unable to initialize RPI_WS281X
    and after copying Hyperiond file from your last post in this thread:

    https://hyperion-project.org/threads/rpi-4-unable-to-initialize-ws281x-library.3680/

    I'm getting that error is "signal".

    I also tried the suggestion "storage/output.txt" from the tread mentioned above. The output is provided bellow .

    Interesting thing is that after a few tries I wanted to check with some other tutorials just for WS281X and followed this one:

    https://tutorials-raspberrypi.com/connect-control-raspberry-pi-ws2812-rgb-led-strips/

    I had to additionally install scons and swig in order for this tutorial to work but in the end, it worked without a problem, all effects were visible on 8 led stripe.

    I tried Hyperion again and still nothing.
    I'm not sure why is this RPI_WS281X tutorial working but Hyperion won't.


    Edit:

    Corrected tutorial link, corrected grammar mistakes, provided links for log, config and output.

    Thanks in advance for your time and help.
