Striptease VS ESP32_FFT_VU

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.

This Scott Marley's esp32 spectrum analyzer got me going into esp32.

It is still bugged, however I've managed to pin it down to one single issue I believe. (thanks to major help.) The sampling rate from the analog input is extremely slow for some reason. It takes a whole 2 seconds to take 8k samples from the A0 pin for a FFT. The code that this is being copied off of online found here: https://github.com/s-marley/ESP32_FFT_VU/blob/master/ESP32_FFT_VU/ESP32_FFT_VU.ino runs 40k samples at 9.2uS even though the code I have for that section is a carbon copy.

Build this based on project from S-Marley on Github (https://github.com/s-marley/ESP32_FFT_VU). My fork is at https://github.com/christiansuryanto/ESP32_FFT_VU . Preview video on Youtube https://www.youtube.com/shorts/Jht9vsqAN1U

Scott Marley has done a great demo with sound reactive lights. The code is very close to what you want with multiple patterns accessed via a button. The code ishere

I'm currently making some mini VU meters on 8x8 and 16x16 matrixes (matrices?). I'd love to be abe to use my patterns from here https://www.youtube.com/watch?v=Mgh2WblO5_c. Code on GitHub here: https://github.com/s-marley/ESP32_FFT_VU/blob/master/ESP32_FFT_VU/ESP32_FFT_VU.ino
