Re: Use ESP32 LyraT-Mini V1.2 with esp-idf-v5.11

E (1198) i2s(legacy): CONFLICT! The new i2s driver can't work along with the legacy i2s driver" You wouldn't be able to run (unmodified) voip example with ESP IDF 5.0 or later version. The reason is ESP IDF switched to the new I2S drivers(i2s_std.h, i2s_pdm.h, and i2s_tdm.h) starting from ESP IDF v...

Re: Custom Board i2s_stream configuration - Cannot pass in custom gpio

When you use ADF, many processes happen in the background. For example, when you call the audio_board_init() function, codecs, adc, I2S, and i2C are initialized. So you cannot have your custom i2s configuration using the same i2s instance that ADF is using(Problem is, ADF mostly uses all the MCU res...

How to initialize LyraT-Mini board's ES8311 and ES7243 without using ADF?

Hello, I want to initialize within the esp32-LyraT-Mini board the codecs ES8311 and ES7243. However, I am not planning to use the ADF. So, I don't want to set all the implicit framework features that happen when the audio_board_init() function is called, which includes, I guess, i2s, and some other ...

What is pipeline listener used for in some examples ?

Hello guys,
I have taken the pipeline_embed_flash_tone example and removed the pipeline listener and it still works fine. So, I am wondering what are pipeline listeners used for ? Is it mandatory, or when is it recommended to be used ?

Has this runtime issue been solved: The new i2s driver can't work along with the legacy i2s driver ?

Hello guys, Has anybody solved the runtime i2s compatibility issue within the av_stream_hal.h and av_stream_hal_audio.c ADF files ? As ESP IDF team has been unable to update these files for the time being to the new i2s drivers(i2s_std.h, i2s_pdm.h, i2s_tdm.h) i am hoping somebody in this community ...

Hello guys, I have a custom board which includes a MEMS INMP441 digital output microphone and a MAX98357 audio amplifier. Not any audio specific codec or DSP chip. So, I wonder if it is still possible to develop ESP ADF applications with this custom board. If not, why? If yes, what should I accompli...

Re: Can 2 ESP-ADF releases be installed at the same time in ESP IDF 5.1.2 ?

It does not matter, I have deleted the oldest version esp-adf-v2.6 because it does not make sense to keep both versions.
Thank you
