Okay. So I've been trying for about a week to get my 276 LEDS to do something...anything...other than a startup effect. Below are my hardware specs:
WS2812B (276 LEDS)
RPi3 w/ latest OSMC installed
Arduino nano (Data pin 10, GRD)
EasyCap USB grabber (UT007)
GANA HDMI2AVI adapter
Sewell Echo Splitter w/ downscaling
Alitove 5V 10A PSU
65" TCL 4K S405
I should mention that I am a noob at this, although I am a computer technician with knowledge of Linux and some programming. I am also aware that there is an issue with 4K HDR signal capture, which I wish was my only issue, as I have seen some work-arounds and I could always just not use HDR until a viable solution is found.
Now for my issue. All that I have been able to produce are start up effects. When my hyperion is started or the Arduino is powered on my LEDs turn green, red, then blue which was specified in the Arduino sketch. I was using a sketch that required understanding of the "prefix" needed, but later discovered a sketch that didn't use it at all, which at least allow me to actually start Hyperion. I am not sure if my USB grabber is correctly grabbing images, as I am not sure how to test it. It is recognized by the raspberry pi, which i was able to verify with "lsusb". The app does connect to the server and I do see the commands executed in the RPi terminal, but the LED do not respond. I've attached my sketch below.
All I can do is stop hyperion, start hyperion and watch these Green, Red, and Blues. SOMEONE PLEASE HELP!
