I've been using a Teensy 3.2 with the OctoWS2811 board and library for the past few years to run much of my Halloween and Christmas light shows. This year, I reworked the code on the Teensy 3.2 to improve the frame rate of the show from 25ms / 40fps to 17ms / ~60fps for 3000 leds. I've shared the updated code at https://github.com/ShadowLight8/fpp-...-serial-ws2813.
