将3W 4Ω喇叭进行连接,其中喇叭一个引脚接 GPIO25,另外一个引脚接地。 六、DAC方式替代Codec方式例程的注意事项 尤其需要进行以下更改: 删除或注释掉执行编解码器芯片初始化的代码: audio_board_handle_t board_handle = audio_board_init(); audio_hal_ctrl_codec(board_handle->audio_hal, AUDIO_HAL_CODEC_M...

之前调用的audio_hw_device_open,就是调用audio.h这个地方,具体实现就是在定义结构体audio_module的地方,不同平台不一样,最终一般都是调用到audio hal的adev_open之类的函数。看下这里的传参:struct audio_hw_device** device,这个结构体就是最终需要open的device。一般的厂商都会封装一层audio_hw_device,因为audi...

When I configure the project, under "Audio HAL", if I set "Audio Board" to "Custom audio board", the project crashes because I don't have a 'board.h' file. So, how can I fix this (use ESP-ADF I2S stream without codec/DSP chip, on an ESP-WROOM-32D)?
