ESP32 Example(s)

[jorgie0]

Hi, The olaf_fp_ref_mem.h included in the zip file from here: https://0110.be/files/attachments/475/ESP32-Olaf.zip

Has a number of nuls on line 7.

In addition to that the content is different from the same file in the arduino sketch folder for esp32_inmp441_olaf

Should the nuls be there? What song does this file represent?

2nd set of questions - When trying to compile the arduino sketch esp32_inmp441_olaf.ino

I found I had to copy the content of the files referenced in the esp32_inmp441_olaf folder. Despite that I have been unable to successfully link the code.

Are you able to provide guidance as to how to build your original hardware and ESP32 code that you used here: https://0110.be/posts/Olaf_-_Acoustic_fingerprinting_on_the_ESP32_and_in_the_Browser For example what ESP32 board did you use and what pins did you have the microphone connected to?

I believe that this is a very interesting project and would like to replicate it.
