Thanks. I'll look in to it asap. PWM is what I'm looking for since I need to control the intensity of each LED (of 40 in total).
Not sure I understand your point. Using NeoPixels / FastLed you could control all 40 LEDs with one pin. Hence, no need for multiple Teensy boards or a library to connect them.fastled support for all supported pins is supported in my libs, but the spi version would be better for that
im not sure for external chips that do addressable leds, but spi would be a requirement for streaming at high speeds

No problem. There are many form factors available:NeoPixels! I've seen the light! (pun intended). Back to the drawing board.
Thanks gfvalo!
That appears directed at me. I've reread my post several times and found nothing I consider offensive. Regardless, no offense was intended.well thats 2 blunt statements, goodbye post.
Yes, I like those. Adafruit calls them DotStar. Only downside is they appear not to be available in the same large range of form factors as the NeoPixels. But, if you can find one that works for your application, I recommend them.Might want to consider the APA102 addressable LEDs. They're a bit more expensive and they need both clock and data, but they update faster for animation and they don't have the fussy timing requirements of the WS2812 LEDs so they're easier to combine with sensors and other things that require CPU.
