    WS2812Serial 400 or 800 kHz

    Does anyone know if the ws2812Serial library use serial to drive neopixels at 400khz or 800khz.

    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.
