    When I use ws2812b driver I get red screen of death and RPi hangs.
    The same thing is with ws281x. So I can not run it with pin 12 - GPIO18.
    I can boot with ws2812b or ws281x when I disconnect grabber then hyperion is failed to start


    I have changed driver to ws2812spi and it partialy works.
    I tried it with RPi B 256MB, RPi B+ and borrowed RPi3.


    On RPi3 it works for a while and then it generaly loosing backlight of right side of TV but I got also from time to time gap on the bottom(begin of LED string) side instead of this left side.


    With RPi B and B+ works without right side (end of LED string) what is more I got LED blinks.
    Booteffect works at start for all leds and setting color of leds from HyperCon also works for all leds.


    added to /boot/cmdline.txt line spidev.bufsiz=32768
    Finaly I would like to use Hyperion on RPi B.
    Could you please advise what I do wrong.
