apa102 flashing only red

  • Hello,


    I've followed no solder tutorial using all HW according to manual - RPi3 and apa102 leds, but I cannot get it work.
    When everything is connected and hyperion installed according to manual, after startup the leds are only flashing red, no rainbow effect.
    After setting manually some color, the leds are also only flashing red.
    Any ideas where can be the problem? HW malfunction, or configuration issue? I've double checked all the wiring, tried to exchange data and clock, soldered the testing circuit, used thicker wires, but every time the same result. Only red flashing.


    For testing I am using circuit with 66leds, with following config:


    Thank you.
