TFLIte demos on Metro M4 Grand Central or Feather M4

by raygeeknyc on Mon Sep 02, 2019 6:37 pm

Hi - I am trying to get the Tensorflow Lite Voice Recognition demos at https://github.com/adafruit/Adafruit_TF ... cro_Speech working on a (feather M4 or Grand Central) - I'm getting the same results on both, but will focus on the Grand Central as the board with the same pins that the code as is calls for.

I'm specifically trying to get the micro_speech_recplay working, on the Grand Central I am uploading the code as it is in the repos.

I've hooked up the microphone breakout and a piezo speaker. In lieu of a pushbutton, I'm shorting the "button" pin to ground with a jumper which seems to be working.

In a nutshell: nothing is recorded - the serial output always reports "Done! Recorded 0 samples"
and, reasonably, the playback is then silent.

A photo of my setup is attached. I think that it's straightforward - just not working. I'll be happy for anyone to point out my obvious mistake(s)! :) or why this is not a workable configuration.
