Basically I am trying to do a led panel driven by the SmartLED V5 Shield and Teensy 4 to do display spectrum analysis.
The demo SpectrumAnalyzer_Analog.ino didn't work. I tried to do an ADC on A2 and just display some results. No dice.
I decided to perhaps instead of doing an audio input circuit to just send serial data from a Processing 3.0 script over serial to the Teensy. After playing around for a while I decided I have no other thoughts on what to try.
The log of my progress can be found here, complete with code for the Teensy and Processing, and some more elaborate descriptions of what I have tried, what I am attempting, and what issues I am facing.
