dueros用例 怎么采集两个mic的数据并保存的SD卡中呢?

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 = ...

在ADF 工程中使用fopen函数

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...

How can I generate 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.
