请问如何在 QCC5171 上启用分频器（crossover）

liyuany

大家好。我想用 QCC5171 做一个双分频主动分频器：一个输出信号给低音喇叭，另一个输出信号给高音喇叭。现在默认固件里这个 crossover 模块还没有启用。有没有人能指导我如何激活它，或者提供相关的资料？如果需要的话，我可以付费来完成这件事。

可以参考adk6.4的方法，也就是qcc512x的adk

MDE:
audio_output_group_main contains:
· audio_output_primary_left //pr
· audio_output_primary_right //pl
· audio_output_secondary_left //sl
· audio_output_secondary_right //sr
· audio_output_wired_sub //subwoofer

#define NUMBER_OF_AUDIO_OUTPUTS 7

Next cod MDE:
if(lp && rp && ls && rs)
{
speaker_config = speaker_stereo_xover; // If you set left primary, right primary, left secondary, and right secondary in ADK, it will be a 2+2 stereo system for bi-amping with crossover separation (2Mid+2Tweeter)
}
else if (lp && rp && sw)
{
speaker_config = speaker_stereo_bass; // If you set lp, rp, and subwoofer in ADK, the DSP chain will be built for a 2.1 system (2MID+SUB) with crossover separation (up to 12th order)
}
else if (lp && rp && !ls && !rs)
{
speaker_config = speaker_stereo; // Regular stereo
}
else if (lp && !rp && !ls && !rs)
{
speaker_config = speaker_mono; // A single mono speaker
}
else
{
Panic();
}
