Compile Issues

[funnyfrish]

you have a #include "ESpeechUserConfig.h" in examples/Basic/basic.ino
and additionaly you have an include in examples/Basic/ESpeech.h with #include "../ESpeechUserConfig.h".
So FFAT does not work anymore we need to use SPIFFS. Im also using a ESP32-S3 with your default pins, but when I try to run it i get
following errors:

E (273606) i2s(legacy): i2s_check_cfg_validity(1000): this i2s port is in use
E (273606) i2s(legacy): i2s_driver_install(1678): I2S configuration is invalid
E (275766) i2s(legacy): i2s_check_cfg_validity(1000): this i2s port is in use
E (275767) i2s(legacy): i2s_driver_install(1678): I2S configuration is invalid

I think I2S port gets initialized twice.

Could you serve us a working version?

Thank you for this great project.

Hi @funnyfrish — thanks for the clear report!

You were absolutely right: the I2S port was getting initialized twice, and ESpeechUserConfig.h was included both in examples/Basic/basic.ino and examples/Basic/ESpeech.h, which also broke FFat/SPIFFS selection. I’ve fixed both issues and verified on ESP32-S3.

What’s fixed

• Single config include: basic.ino no longer includes ESpeechUserConfig.h. The config is now included only once from the library.

• I2S init/deinit: guarded single initialization and proper i2s_driver_uninstall() on shutdown. This clears:

  i2s_check_cfg_validity: this i2s port is in use
  i2s_driver_install: I2S configuration is invalid
  

Versions to use

• ESP32 Boards Manager: 3.3.1
• ESpeech v2.0.1 (updated)
• Wakeword: latest Marvin_WakeWord_inferencing

Storage selection

In ESpeechUserConfig.h (inside the library), choose one:

// SPIFFS:
#define ESPEECH_USE_SPIFFS 1
#define ESPEECH_USE_FFAT   0

// or FFat:
#define ESPEECH_USE_SPIFFS 0
#define ESPEECH_USE_FFAT   1

ESP32-S3 I2S pins (match your wiring)

#define ESPEECH_I2S_BCLK  17  // SCK
#define ESPEECH_I2S_WS    16  // LRCL
#define ESPEECH_I2S_DIN   15  // SD

Clean install tips

• Remove any old copies from Arduino/libraries, then reinstall the updated libraries.
• If using FFat, pick a partition scheme that includes FFat and format/mount on first run.

Thanks again for catching this. If anything else pops up, let me know!
