nrf52 Continuous Speech Demo Error: "PDM.h file not found" #4

Hardware: Circuit Playground Bluefruit nRF52840 [Cortex M4 processor]

Issue Description: I am trying to run the "micro_speech_continuous_nrf" demo under "nrf52" directory. I am getting the following error:

audio_provider.cpp:17:17: error: PDM.h: No such file or directory

 #include "PDM.h"

                 ^

compilation terminated.

exit status 1
PDM.h: No such file or directory

Is the tensorflow lite library missing this file ? I have installed Adafruit's TFLite library from Arduino as well as the other required libraries. Thanks.

hiya you'll need the master branch of https://github.com/adafruit/Adafruit_nRF52_Arduino because we haven't done a board release since adding PDM support!

Awesome. Thank you so much. Just one last thing. I have trained a Tensorflow model and saved a TFLite model from that. Is there any tutorial present or coming up explaining about how to go from that TFLite model to Arduino/nRF52 or any other platform? Thanks.

the nrf52 doesn't quite have the drag-n-drop code yet, may be a few weeks so for now you have to xxd'it into the header file by hand. check the tensorflowlite dox for info!
