Question about clocked chips. I’ve always worked with ws2812B srips, but after hearing how good APA102’s are, I’m thinking of using them on a newer project that would involve longer runs of strips. I guess my question is, do you need to run a clock line for each LED strip, or can you somehow split the single clock pin to each strip, and then obviosuly there would be a data pin unique to each strip?
Right now you do, yes. Round 2 of the library’s parallelizing code will be tackling the 4 wire led chipsets.
(though, there is an open question about how many ways you can split the output of a single pin and still have a usable signal)
if the lines arent sent parallel anyways, couldnt you just switch the single clock line to the appropriate data line as each one is done? I have little understanding of the underlying protocols so that might be a dumb question.
Also, surely theres chips out there made to duplicate signals cleanly?
