hi, I have a stm32l476 necleo-64 board and CCA02M1 extension board. I want to modify the the Microphones_Streaming example. and I want to use it to record 4 channel microphone and with 48000Hz sample rate. and I just change the macro definition AUDIO_CHANNELS in the aduio_application.h. change the 2 to 4
&sharpdefine AUDIO_CHANNELS 2 ------------> 4
but the Audacity didn't work after the change,it reprot error like this
and the the same thing happens when I change the AUDIO_SAMPLING_FREQUENCY to 48000
and I think mabe I should change the USB descripter at the same time, but how to modify it ?

There are perhaps specification documents that might be enlightening..

Hello,
You need to change the sittings of you'rerecording device on windows: Audio sampling frequency and Audio channels.

Hey, Zhangyi, have you managed to change the code? I'm facing the same issue. You probably have to change some code in the USB driver and solder/unsolder some resistors in the X-NUCLEO board. I'm okay with the soldering stuff, but the coding is driving me nuts hehe

Hello I need your help, I work with stm32f401RE, I would like to do the project Microphones_Streaming and after doing the LS_application ''localization source'', I did not use the x-nucleo-cca02m1 but I did a montage paraille, I know why my pc does not even detect the door of the acquisition, and because of the mounting X-nucleo-cca02m1 thank you
