It is hoped that ESP-ADF can add programs to support PCM5101 drivers (AUD-6160)
Hello:
Since PCM5101 is used on several pieces of hardware here, it is hoped that PCM5101 driver can be added:
It is hoped that ESP-ADF can add programs to support the following operations:
1, speaker and microphone use two I2S (speaker one way, microphone one way, the use of pins can be modified in the example, without modifying the underlying file)
- Since PCM5101 has no hardware volume adjustment interface, it is hoped that the volume adjustment function is not directly empty, and the volume adjustment can be achieved by adjusting the software gain
3.PCM5101 does not require an I2C interface
At present, it is mainly used on DLNA, so the compatibility can be based on DLNA sample test
At present, ADF only sees ESxxxx type number decoding chip, hoping to add some models
Looking forward to receiving relevant reply!
客户 需要根据自己硬件去添加相应的 codec， sdcard 等外设，每个客户的硬件不一样。 所以可以参考 我们现在已有的板子
@shootao 你好，请问一个问题，我自定义的板子，能够使用示例里面的代码录音，但是接入豆包AI_AGETN这个例子的时候一直卡住录音这部分，另一个房间的用户收不到声音，能播放远端传过来的声音，而且使用这个例子的录音声音比较小，但是能听清。 examples\recorder\pipeline_raw_http ` ESP_LOGI(TAG, "[ 1 ] Initialize Button Peripheral & Connect to wifi network"); // Initialize peripherals management esp_periph_config_t periph_cfg = DEFAULT_ESP_PERIPH_SET_CONFIG(); esp_periph_set_handle_t set = esp_periph_set_init(&periph_cfg);
