I'm picking up on Audio + LED strips because my 13 year old is bugging me for a cool led strip in her room... responsive to audio (amplitude and pitch). I offered this to her 2 years ago, but bailed on this project shortly thereafter because of (probably) interrupt conflicts between the audio library's FFT1024 and the fastLED library's simultaneous use of interrupt routines.
I'm back on it.
I have the "Teensy 3.2 OctoWS2811 Adaptor" and can run examples\Octo...\rainbow installed with Teensyduino.
I'm using a Teensy 3.2 and have 3.6's in stock.
The latest Arduino and Teensyduino is installed on a Mac accessible to her.
I've not added back the Audio yet.
By default, I'd plan to use a Neutronned mic and the ADC input from the audio library... piped into an FFT1024 object.
I've seen other posts about the interrupt problems... one suggesting disabling the audio interrupts before executing the LED update call, and reenabling thereafter.
What's the best practice for making a frequency-and-amplitude-responsive LED strip?
Thanks!
