RPI3/Zero + Raspbian Stretch + Hyperion + WS2812b

  • Hi,
    I have RPi3 with updated Raspbian Stretch and WS2812b LED strip connected to GPIO18. Wiring is ok. I am able to control LEDs over python script (rpi_ws281x - https://github.com/jgarff/rpi_ws281x ).


    When i started hyperion daemon, all LEDs are turned off. I used logical analyzator to show state of GPIO18. Output of GPIO is still on low level. When i stop daemon, sometimes LEDs blink for few miliseconds! I see 24bits of data (for one LED) on logical analyzator!


    What is wrong with hyperion?


    State of GPIO on starting and stopping hyperion:


    Detail "hyperion end"



    Output of hyperiond:


    Config:

  • I made progress. I must to uncheck "smoothing enabled" and then run "/usr/share/hyperion/bin/./hyperiond /etc/hyperion/hyperion.config.json". Application will hang on "EFFECTENGINE INFO: Initializing Python interpreter". Here is output:




    ...then I must press CTRL+C and after that is application started properly..





    Hyperiond service is hanging on "Initializing python interpreter"..
    Any suggestions? Thank you
