LED_Matrix
My personal project with a 47x60 LED matrix. You can see it in action here: https://imgur.com/gallery/tSoa2W6
My LED matrix is wired differently than the OctoWS2811 library expects. Because of this, I had to modify the library. While I was at it, I made other optimizations to the audio library. All the changed files that need to be updated are:
C:\Program Files (x86)\Arduino\hardware\teensy\avr\cores\teensy3\Arduino.h (need to verify this, if changed) C:\Program Files (x86)\Arduino\hardware\teensy\avr\libraries\Audio\analyze_fft1024.cpp C:\Program Files (x86)\Arduino\hardware\teensy\avr\libraries\Audio\analyze_fft1024.h C:\Program Files (x86)\Arduino\hardware\teensy\avr\libraries\OctoWS2811\OctoWS2811.cpp
Arduino.h defines the preprocessor constant. The other files include changes around this preprocessor directive. The .ino files look it as well. Edit: Actually its not there. Arduino looks at the header files first before looking at any .ino files. I can't define the preprocessor in my ino files. I need to make a new header file that defines the constant.
