just like Christmas music, more than once is too often. testing at 921600 kbaud, strips are ordered and acting as one giant contigous strip now.

Looking much more stable and smoother now Charlie, nice work. Did you change anything to improve it from when we came over before Christmas?

I made some progress on doing something similar with the Teensy 3.1 for the FLED. Got it working with a single strip and buffering 10 frames ahead, was working well. Sadly I didn't take into account just how much data we're talking about when we scale up to the full 32x54 pixels. 1728 pixels = 5184 bytes per frame = 155520 bytes per second = 1244160 baud! So I guess that's not going to work with a single chip. Considering running two, at 921600 but I'm not sure how well that'll work. More testing to be done.
