LED Strip not lighting up

    • Neu

    I followed Everything Smart Home's guide to set up ambient lighting for my TV, but I'm facing an issue where nothing is lighting up. I separately tested the LED strip and confirmed that it works, so that's unlikely to be the problem. I can access the Hyperion page through my browser and have followed the guide's instructions for setup and assembly. Occasionally, when plugging in or removing cables, parts of the LED strip light up momentarily, but it still doesn't work as ambient lighting.


    In Hyperion, I've selected SK6812SPI as the controller for the LED strip. I've also tested GPIO pin 18 on the Raspberry Pi with a PicoScope and confirmed that there's data flowing through the pin.


    I've double-checked all connections multiple times and don't believe it's a hardware issue on that front — at least not with the connections.


    Hardware List:

    • BTF SK6812 5V, 5M with 60 LEDs per meter
    • Raspberry Pi Model 4 B
    • AC/DC Adapter 5V10A, model YU-0510

    Software:

    • Hyperion V2.0.16

  • Lord-Grey

    FYI: I found the issue, but don't know how to solve it. It's a hyperion issue, since there is no data flowing to Pin 12 (GPIO 18). What i thought was data, is simply the ambient electricity that the PicoScope picked up through that pin. I can access the Hyperion site through my browser, and everything looks to be working. Just no signal going to Pin 12?

    Here the SK6812 300leds 5 meters Raspberry PI3B+ 5V 10A power supply works very well, also with Netflix everything in HD (4K unfortunately not) also YouTube on Google TV Sony Bravia, Youtube app in Sony Bravia works well with Hyperion Android grabber,


    Statelliet TV works via USB3.0 Video Capture card, Netflix in HD and Disney+ works on Nvidia Shield TV via the USB3.0 Video capture card, (without the USB 3.0 Video Capture card I have Netflix in 4K but no LEDs)




    To get it working I placed a diode for the first LED see link: https://hackaday.com/2017/01/2…-to-use-a-3-3v-data-line/ this may not have been once needed.




    GPIO10, SK6812 spi, SPI Pad 0.0 Baud Rate 3900000 and lastly


    add spidev.bufsize=1024000 in /boot/cmdline.txt, which was set to 4096 instead of 1024000. After I increased the buffer, all LEDs worked properly instead of 1 or 3 or 10 LEDs and everything was white or flashing.




    Once I had all the LEDs working, I only had to invert the colors red and green and cyan and magenta during image processing.




    I hope it will help others and that it will work too.
