I'm not sure. It's like noise, not the mic data

Thank you for your advice。 How to use function i2s_read_bytes() to read mic data? The I2S configuration is as follows. but, I cann't get the mic data. i2s_config_t i2s_config = { .mode = I2S_MODE_MASTER | I2S_MODE_RX | I2S_MODE_TX, .sample_rate = 48000, .bits_per_sample = SUPPOERTED_BITS, .channel_f...

怎么通过i2s_read_bytes()函数读取mic数据啊？需要配置什么参数吗？ I2S配置如下： i2s_config_t i2s_config = { .mode = I2S_MODE_MASTER | I2S_MODE_RX | I2S_MODE_TX, .sample_rate = 48000, .bits_per_sample = SUPPOERTED_BITS, .channel_format = I2S_CHANNEL_FMT_RIGHT_LEFT, .communication_format = I2S_COMM_FORMAT_I2S, .dma_buf_count = 3,...

dueros用例 怎么采集两个mic的数据并保存的SD卡中呢？目前只能保存rec_engine_data_read(voiceData, ONE_FRAM_SIZE, 110 / portTICK_PERIOD_MS);中voiceData数据，这个应该是重采样后的数据，只有1路数据。 dueros 能通过修改重采样后的通道数获取两路mic吗？我尝试了一下，采集到的数据信号不对 i2s_stream_cfg_t i2s_cfg = I2S_STREAM_CFG_DEFAULT(); i2s_cfg.type = AUDIO_STREAM_READER; i2s_stream_reader = ...

ESP32-LyraT开发板 能够获取播放器的参考信号吗？或者哪个用例可以获取参考信号？

我想在ADF 工程中使用fopen函数，例如在dueros测试用例中保存文件到sdcard中，但是总是报fopen错误，在新版本的IDF工程可以测试通过。 错误如下： (0) cpu_start: Starting scheduler on APP CPU. I (58) example: Initializing SD card I (62) example: Using SDMMC peripheral E (142) sdmmc_cmd: sdmmc_card_init: send_scr (2) returned 0xffffffff E (142) example: Failed t...

I don't know which project to compile to generate Bootloader.bin,partitions_esp_audio.bin, esp32-audio-app.bin and audio-esp.bin files

How can I generate Bootloader.bin partitions_esp_audio.bin esp32-audio-app.bin audio-esp.bin files?

After the ESP32 LyraT V4.3 development board is connected to the DuerOS cloud platform, ESP32 core can hold the "Alexa" wake-up call.

Refer to the ESP32-LyraT user guide, how to achieve the "Alexa" wake-up function？
