According the Microphone array library V2.0.0 manual,if i set MIC_ARRAY_MAX_FRAME_SIZE_LOG2 = 9 buffering_type = DECIMATOR_HALF_FRAME_OVERLAP in decimator_config_common.
Now I got 512 samples by Frame, but i don't know how to sent it to USB,there is not demo code in website.
mic_array_frame_time_domain * unsafe current = mic_array_get_next_time_domain_frame(c_ds_output, 1/*2*/, buffer, mic_audio, dc);
c_audio :> req;
for(int i = 0; i < NUM_PDM_MICS; i++)
c_audio <: (int)output;
