I’m looking at the APA102’s and considering FastLED. Does it support parellell output for the APA102 aka dotstar LEDs?
Not yet - mostly because the apa102 default data rate is high enough that it blows parallel ws2812 out of the water, so I haven’t had a lot of motivation to do it yet. That said, there is a way to drive four apa102 lines on the teensy 3.x, not in parallel, but all in hardware, documented here: https://github.com/FastLED/FastLED/wiki/SPI-Hardware-or-Bit-banging
It’s more of a wiring issue wanting them treated as separate strips vs daisy chaining them all together
Thanks for the pointer on the SPI + Teensy
You can run multiple controllers on different pins. Scroll down to “Multiple led arrays”…
However, multiple controllers is different from parallel output (parallel output gives you performance improvements from writing out the multiple lines in parallel vs. serially, one after the other)
