APA102 - Arduino-Nano - RPi3

  • Hi guys,


    i try to get a running Ambilight.


    I have all assembled and connected, but only get "white lights" on start, nothing else.
    I hope someone could help me a bit, to find my error(s).


    Hardware:
    APA102 (202 LEDs)
    RPi3
    Arduino Nano - Bus 001 Device 004: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter
    HDMI-Splitter
    USB Grabber - Bus 001 Device 005: ID 1b71:3002 Fushicai USBTV007 Video Grabber [EasyCAP]
    5V Power supply 100W


    OS - LibreELEC-RPi2.arm-8.2.3.img.gz


    I used Hypercon for installation, create & transfer config ...



    For the Arduino i use this sketch. (pin D6 data, pin D13 clock, gnd)


    install log


    start log


    start log without boblight



    when i connect my STB to the HDMI-splitter i can get Pictures from the grabber.
    when i connect the rpi, no picture.
