Getting working on an Arduino Nano ESP32?

[jonagill]

Hi all,
Sorry for what's possibly a silly question, but does anyone know what it would take to get this library working on an Arduino Nano ESP32? I believe the hardware itself should be compatible, since the Nano ESP32 has an ESP32-S3 chip, but I'm not sure if the libraries themselves area. The official Arduino Nano ESP32 board SDK seems locked to version 2.0.18 of the ESP32's libraries. I'm not sure if that will be an issue or not, because when I try to compile the example code on the homepage, I get an error that I think suggests I'm targeting the wrong C++ version:

In file included from /Users/jonagill/Documents/Arduino/libraries/ESP32-audioI2S-master/src/audiolib_structs.hpp:2,
                 from /Users/jonagill/Documents/Arduino/libraries/ESP32-audioI2S-master/src/Audio.h:10,
                 from /private/var/folders/12/1zxcj3s15m17t8qg1ckvgd3h0000gp/T/.arduinoIDE-unsaved20251022-43976-1w9hesd.ii1pl/sketch_nov22b/sketch_nov22b.ino:3:
/Users/jonagill/Documents/Arduino/libraries/ESP32-audioI2S-master/src/psram_unique_ptr.hpp:8:10: fatal error: span: No such file or directory
 #include <span>

Printing out __cplusplus gets me 201103, so I think the Nano is still using a very old standard. Oof.

Sorry if this is a very basic question. Let me know if you have any ideas about if/how I can get this library working with the Nano. Thanks!

Answering my own question — espressif's own Arduino development core has a configuration for the Arduino Nano ESP32 that works perfectly. (It's just buried in the middle of the list of boards and kind of hard to spot.)
