    Any pointers on how to modify the library to run at 400kHz? I am trying to drive a run of 60 APA106 LEDs with a Teensy 4.0 (via a 74AHCT125) and the last 15 are flickering significantly. I can duplicate the flickering effect using the Neopixel library with the 800kHz option - it is fixed when the 400kHz parameter is selected instead.
