I've spent quite a bit of time stringing up long chains of shiftbars (160), and in my experience I seem to always run into some kind of glitching/flicker scenario, usually when all LEDs go to full brightness, which makes me wonder if it's power related (I've tried different power supplies, and splicing in power regularly to help voltage drop). Fussing with the current values (going lower) sometimes fixes it, but the longer the chain the harder it is to combat. Mace any suggestions? The behavior of this chip, while on paper is straight forward, in practice has some crazy ju-ju going on....
