If I read the (minimal) ws2811 reference / spec sheet correctly, doesn't the chip act as a signal repeater / reshaper on the DI line? If so the signal quality should only matter up to the first chip in the line, isn't it? Maybe you could wire up the scope to the DI-out of a chip and compare it...

Hehe, I skipped the whole ISR stuff and just looped through Serial.available() with a 1mbit serial setup. Seems like Teensy3 has enough power to munch all that data without any special stricks, at least for the tiny matrix I have set up here...

Thanks Paul for pointing me in the right direction. 1-byte Fifo is exactly what I need, I just have to find the right ISR vector that gets caught when there is a byte available. It's not a library, but a sketch for the receiver side of a software that generates LED matrix animations: Glediator...

Hello everyone, I just received my first Teensy 3.0 and am a bit exited right now ;) Guess you all know that feeling... Now there are quite some questions evolving, which most boil down to read the 1k2++ pages of specs... guess I am spoilt by the vast arduino code base. Seems like everything...

Thanks for the prompt response Woozy! I will also have a seperate power source for the strip and the Teensy, so I suppose it should be fine here too.

Hi everyone, stepped into this coming from Arduino and driving a ws2811 strip. I Just ordered a Teensy 3.0 to get some more calculation power for realtime matrix content. Now that I have read a bit further I am wondering whether I need a level shifter to drive Din on the LED strip or not. Does...
