I do not understand your question.
Maybe you could tell us which hardware you really have and what you're trying to accomplish?
Here's some generic answers that may or may not apply.....
The OctoWS2811 code runs on Teensy 3.x. The Arduino+Teensyduino software is used to program your Teensy. Most people use a regular PC or Mac to run the Arduino software, because Raspberry Pi is so slow. But you can run the Arduino software on a Raspberry Pi if you really want (and if you have a lot of patience).
There are 2 basic ways to use OctoWS2811. You can program all the animation to be done using code on the Teensy. Several of the examples that come with OctoWS2811, like BasicTest, PlasmaAnimation, Fire, & SpectrumAnalyzer work this way. Everything happens on the Teensy, so all you need is power to the Teensy and the LEDs will do whatever you've programmed. While this way gives you a very self-contained and highly reliable project (doesn't depend on a computer) it is harder to create really complex animations or video streaming using only Teensy.
The other way involves sending data to Teensy, which it then sends to the LEDs for you. Other OctoWS2811 examples like VideoDisplay, Artnet, Adalight & Glediator work this way. Software running on a PC or Mac or a board like Raspberry Pi sends data to the Teensy. Even if you intend to use a Raspberry Pi to send the data, this sort of project is easier to do by first using a regular PC or Mac. You'd run the data-sending software on your regular computer, and run Arduino on your computer. Once everything is working, then you'd plug the Teensy into the Raspberry Pi and try to run only the data-sending software on the RPi. This may seem harder because it adds an extra step to switch to the RPi, but believe me, this way is much easier because a regular computer is so much faster and easier to use for development & testing than the slow Raspberry Pi.
