I've been asked to interface with some LED strips that use SM16704 pixel chips.

A site search here doesn't show any mentions of this chip, so I wonder if anyone knows if they're compatible with the more common ones like WS281x and can be addressed using FastLED or other library?


Here's the datasheet for the -PB version of the chip. I can't find one for a plain 16704 but I don't think the protocol is any different.

    the timing is quite different ... you could rewrite the library

The best data I can find says that this chip / protocol is compatible with the WS2813 and should require only a minor tweak, if any.
