Hello, I'm driving APA102 LEDs with shiftout, and while for on-off speed is ok, when I want to do some cool and fast color change, speed is not enough.
So as I understand, SHIFTOUT is just making data pin high-low with required bits, synced with clock pulses, right?
So maybe there's a code which can do this at faster rate, than shiftout does? without using MSSP, 18F series and so on.
