Just a thought on nomenclature...
In the RGB LED strip project I've been describing, I'll use "NRZ" to refer to the zero and one waveforms sent to the WS2811, reflecting how the datasheet describes them. This is technically not accurate... The scheme they use is an isochronous self-clocking line code, but I'm not sure it really has a name. In some ways one could think of it as being a variation of Manchester encoding, though not quite.
Anyway, it's easier to refer to it as "NRZ", so deal with it. :-)
