Variation of Tutorial

Post by splatten »

Is there a variation of the tutorial on creating an Arduino Music Visualizer using an LED matrix?

Thank you

We just have the one with the bi-color matrix.

I have a 16x32 matrix, any hints on using this?

The GFX library works on that display also. Obviously, everything needs to be scaled up to the larger matrix size.

The code is optimized for performance. With 8 times as many pixels - and full color, I'd expect it to be noticeably slower.

There is a comment on the page about it not being compatible with teensy and other controllers. I would like to use a teensy 3.1
Finally, because ADC registers are accessed directly, specific interrupts are used, and the FFT code is in AVR assembly language, this software will not run on upscale boards like the Arduino Due, ChipKIT or Teensy 3.0. It is strictly for “classic” Arduinos.

I believe that PJRC has an FFT library for the Teensy. Paul's code is usually pretty well optimized also, so I'd expect good performance on that platform.
