WS2812Serial VS Striptease

You could try the WS2812Serial library for the Teensy instead of FastLED for a further test. It also works with Pin 17 on the Teensy 4

A very good alternative to OctoWS2811 is the WS2812Serial library, by Paul Stoffregen too.

I confirm https://github.com/PaulStoffregen/WS2812Serial works great with Teensy 4.x.

Use WS2812Serial instead, as suggested in the posts you mentioned.

BTW, if you're using a Teensy 4.x you might be interested in my project.

I'm not aware of any general significance of DrawOneFrame functions. They don't invoke any particular FastLED behaviour. For projects where a variety of different effects can be presented, the author may choose to use C++ classes to provide a standard interface to initialise and display those effects. In my WavyDots sketch, that function name is a vestige of such a choice. The Aurora project does something similar. So does the Striptease project, but there the DrawOneFrame function is simply called loop.

Have you ever come across my project? Perhaps you might find some interesting ideas to borrow.

Hi, I faced the same problem in my project.

In my project I did something similar and created abstractions for composing virtual strips by joining, extracting a portion or reversing other virtual or physical strips. Have a look at the Strip API.

That's what I'm using in my project based on Teensy 4.1 + Audio shield for driving 6 channels in non-blocking mode and it works great!

I'm using it in my project for driving 6 channels (Teensy 4.x) without any problems.

If you plan to use the Audio shield in your project (as I do on mine), then two Serial ports won't be available (pins 8 and 20), leaving you with 3 and 6 serial ports available on standard pins.

I have developed a library/framework for this, and it allows decoupling the physical layout of your strips (up to six) from the logical layout.

Hi, have a look at my project. It's a library/framework for Teensy 4.x + Audio Shield.
