    Hello everyone

    The first LED of the strip is staying on white or green and not following the displayed colors from the capture software or effects from Hyperion. Sometimes the first LED is off and not lighting up at all, mostly when I first power up the setup. Then after a short while the first LED comes on and stays white.

    This started when I added a level shift converter to the data line GPIO 10 on the Pi3. The level shift converter has solved the random color flickering, but the first LED is a problem now.

    Besides the first LED the setup is working well.

    Anybody know why or how I can fix this ?


    - +/- 7m 402 LED strip SK6812 RGBW

    -Raspberry Pi 3

    -5v 60amp power supply powering the leds and pi

    -Capacitor across the positive and negative power wire to the led strip

    -Baud rate 5000000

    -I had a resistor inline on the data line but that caused the led strip not to work at all with the level shift converter.

    -Capture source: Hyperion Screen Capture

    Any help would be greatly appreciated.

    Hi everyone

    I'm using the Pi3 with a 5m + 2 x 1m strips of SK6812 RGBW total of 420 leds, I can't address more than 255 leds.

    From the other threads it looks like I need to set my max_led, but I don't know where or how.

    I need to run a 7m strip for my 100" projector screen.

    any help would be greatly appreciated.
