boosting the SPI bus core for this ledstrip seems a little out there, hope it works! we tried almost everything
normally SPI bus can't run faster then core freq speed?
7000000 is 700Mhz thats really high (to high)
Or use the LEDs on pin 12 (GPIO 18) in PWM mode, then select ws281x in Hyperion.
on sk6812 using this ledcontroller, ws281x > if it works doesn't need to run Hyperion.NG under root all the time?
i never read that people where steering these leds on PWM so thatswhy i go the SPI bus route with him.
well, i hope he fixes this because this ledstrip is a pain in the **
