aanc应该如何配置使用?
在5171evb上配置aanc,用了一个模拟mic插在mic1上,code做了以下修改:1. 添加了ENABLE_ANC、ENABLE_ADAPTIVE_ANC 宏
2、subsys3_config2.htf
DigMic0PioConfig = #define appConfigMic0Bias() (BIAS_CONFIG_MIC_BIAS_0)
#define appConfigMic0BiasVoltage() (3) /* 1.9v */
#define appConfigMic0Pio() (0x13)
#define appConfigMic0Type() (mic_type_analog)
#define appConfigMic0AudioInstance() (AUDIO_INSTANCE_0)
#define appConfigMic0AudioChannel() (AUDIO_CHANNEL_A)4、kymera_config.h
#define appConfigAncPathEnable() (feed_forward_mode)
#define appConfigAncFeedForwardMic() appConfigMicVoice()
#define appConfigAncFeedBackMic() (MICROPHONE_NONE)
没用过,这个应该有官方文档,
