Teensy 4.0 and FastLED along with WS2811 or NeoPixel RGB LED

Hi Everyone:

As u/im2legit2quit and u/Elektrobomb have posted on http://www.reddit.com/r/FastLED/, you need to use FastLED’s parallel output procedure to make the new Teensy 4.0 work with FastLED and with NeoPixels, WS2811, WS2812 and WS2812B RGB LEDS even if you are only using one strip, ring or matrix. That procedure is found here:

https://github.com/FastLED/FastLED/wiki/Parallel-Output

Scroll down to: “Parallel output on the Teensy 4”.

Here is a sketch that I wrote which illustrates how to do this:

FYI, putting in NEOPIXEL as the chipset does not work. You have to use WS2812B for this chipset.

Best Regards,
