I suppose once you get past the low hundreds of devices, it makes sense
to split it into multiple blocks with a dedicated controller looking
after them.
I looked at that - and it seems to use something called DMX over
Ethernet aka E1.31 aka ArtNet(?).
DMX and DALI I've heard of, but not E1.31
If *I* were doing this, I think I would stick to my Pi idea
Yes if I had a Pi I'd use it instead of USB-sync, just do your own
bit-banging, you could probably drive 8 strings of RGB LEDs per GPIO port.
I wonder how practical that would be - bit banging at 400kHz (is that
right - it's been a while?) - seems a pretty realtime operation for a
full on OS like linux (unless you actually use RT features or write it
as a kernel driver or something???
