Getting working on Arduino Nano ESP32?

[jonagill]

Hi there! Sorry if this is a basic question, but I'm trying to find a library for playing an AAC web stream that works with the Arduino Nano ESP32. I've installed your library via the Arduino IDE, but I get this compilation error when I run it:

In file included from /private/var/folders/12/1zxcj3s15m17t8qg1ckvgd3h0000gp/T/.arduinoIDE-unsaved20251022-43976-nefltf.vnzhk/BeepSpeech/BeepSpeech.ino:13:
/Users/jonagill/Documents/Arduino/libraries/BackgroundAudio/src/ESP32I2SAudio.h:24:10: fatal error: driver/i2s_std.h: No such file or directory
 #include <driver/i2s_std.h>
          ^~~~~~~~~~~~~~~~~~

I'm guessing this is because the official Arduino ESP32 Boards package seems locked to version 2.0.18, which I'm whereas the official espressif packages seem to be up to version 3.3.4. I'm not sure when i2s_std.h was added, but I'm guessing it's not in the version Arduino is still packaging.

Anyway, sorry again if this is a silly question. If anyone has good ideas for if/how I can get this library running on my Nano, I'd be very grateful!

FWIW, this library needs the "new" (actually several years old by now) 5.x or later IDF.

Why not install the ESP32 Arduino core and use that to build? https://github.com/espressif/arduino-esp32 has directions.

Ha, because I'm a fool who can't read lists very well! I tried using the ESP32 Arduino core but ran into issues flashing using the ESP32S3 Dev Module setup. I didn't notice that buried deep within the list of boards for that core, there's an entry for Arduino Nano ESP32 that compiles perfectly.

Thanks for the help!
