Custom Board SPH0645

Postby JVKran » Thu Mar 04, 2021 3:08 pm

Hi there!

I've been playing with a custom board definition for the ESP-ADF and am now facing some issues with the examples including a microphone. I just get no input... I've got one single clue that isn't resulting in any search results on some major search engines. That's the following 'E (10715) AUDIO_ELEMENT: [wav] Element already stopped'. Underneath I pasted is the entire terminal output.

I have to mention though, that I have no codec. I'm just using the example of a [custom board definition](https://github.com/espressif/esp-adf/tr ... d/play_mp3) where I made sure the SD card is initialized succesfully (can playback fine) and the Microphone Data Out pin corresponds to the I2S input of the I2C configuration. This custom board is currently based on the ESP32 S2 WROOM of the LilyGO TTGO T8 ESP32 S2 WROOM.

Oh and by the way, this is my first post. So please mention it if I've done something wrong.

Kind regards,

An interested (but confused) Jochem

For any future visitors; I ended up ditching the SPH0645 since it appears to be incompatible with the I2S timing of the ESP32. The INMP441 or (newer) CMM-4030D work perfectly!

Hi,
could You please tell how You managed to work INMP441 microphone?
I'm struggling with it fore some time and only thing I can get is noise.
I have a custom board with connected UDA1334 DAC, which works as it should.

Hi Johny,

Of course I can! Using the I2S configuration underneath in combination with the sd-card example results in a clear recording. You of course have to replace I2S_STREAM_CFG_DEFAULT with I2S_STREAM_CFG_INMP.

Code: Select all

#define I2S_STREAM_CFG_INMP() {                                              \
    .type = AUDIO_STREAM_READER,                                                \
    .i2s_config = {                                                             \
        .mode = i2s_mode_t(I2S_MODE_MASTER | I2S_MODE_RX),                    \
        .sample_rate = 44100,                                                   \
        .bits_per_sample = I2S_BITS_PER_SAMPLE_16BIT,                           \
        .channel_format = I2S_CHANNEL_FMT_RIGHT_LEFT,                           \
        .communication_format = I2S_COMM_FORMAT_STAND_I2S,                            \
        .intr_alloc_flags = ESP_INTR_FLAG_LEVEL2 | ESP_INTR_FLAG_IRAM,          \
        .dma_buf_count = 6,                                                     \
        .dma_buf_len = 400,                                                     \
        .use_apll = true,                                                       \
        .tx_desc_auto_clear = true,                                             \
        .fixed_mclk = 0                                                         \
    },                                                                          \
    .i2s_port = I2S_NUM_0,                                                      \
    .use_alc = false,                                                           \
    .volume = 0,                                                                \
    .out_rb_size = I2S_STREAM_RINGBUFFER_SIZE,                                  \
    .task_stack = I2S_STREAM_TASK_STACK,                                        \
    .task_core = I2S_STREAM_TASK_CORE,                                          \
    .task_prio = I2S_STREAM_TASK_PRIO,                                          \
    .stack_in_ext = false,                                                      \
    .multi_out_num = 0,                                                         \
    .uninstall_drv = true,                                                      \
}
Hope this could be of help.

Kind regards,

Jochem

hi can you please guide me how you did that?? do i need to make custom function for that
i replaced I2S_STREAM_CFG_DEFAULT with I2S_STREAM_CFG_INMP in main file but flashing shows error "implicit declaration of function 'I2S_STREAM_CFG_INMP'; did you mean 'I2S_STREAM_CFG_DEFAULT'?"
please tell me how can i achieve any recording out of my esp32 audio kit..... i am only getting blank audio....
