Hello, I'm looking for some advices regarding APA102 LED Strip.
I've used a lot FastLED library but it now lacks support to Teensy 3.5 and I've researched some options.
One of them is this one https://github.com/pololu/apa102-arduino
which is very simple, and allows you to use only one pin as Clock for all output ports, saving pins.
in my project it would be OK because all strips are in sync.
But testing I've found it is a lot slower than FastLED. FastLED itself gets confused when sharing Clock pins.
It may be because I'm using pin 14 as Clock and it consider SPI. If I force a slower datarate, about 4 Mhz things start to work.
Do you have any recommendations of libraries, or techniques? I would love an APA102 only library with performance similar to FastLED.
Thank you
