Hello,
I've built prototype ambilight system for Linux Ubuntu based node, X11 grabber for data capturing, Arduino Nano with FastLED and Adalight sketch (using this tutorial https://sudokin.com/diy-arduin…s2812b-full-build-how-to/). And now I see that with 115200 baud of serial connection I have about 62 fps update rate for 60 LEDs. But I want more - 300 LEDs or maybe even more. What hardware/software combination allow to achieve those values?
Probably additional RPi can help here, but use of USB/Serial device for driving LED is so tempting here as I don't want to have all that burden with video signal splitting/capturing. And this ambient light system aimed for video wall configuration (say 5x1 monitors ) which will be not easily handled by RPi anyway.
Can you please guide me to possible solutions suitable for this case (x11 grabbing at input, 300+ LEDS driven at output) ?
Thanks!
