How to add USB Serial port to XMOS Reference Audio project ?

[networkaudio]

Would love to see this on the newer platform. Have been tasked with doing USB to 8 analog bidirectional line level audio channels and 8 bidirectional RS422 and doing this all in one device would solve so many issues.

Do you have an xcore.ai multichannel audio board?

If so you can spin up the code here:

In a fresh sandbox:​

• git clone -b feature/cdc git@github.com:ed-xmos/sw_usb_audio.git​
  
  cd sw_usb_audio/app_usb_aud_xk_316_mc/​
  
  cmake -G "Unix Makefiles" -B build​
  
  xmake –j –C build 2AMi8o8xxxxxx_cdc​
  
  xrun --xscope bin/2AMi8o8xxxxxx_cdc/app_usb_aud_xk_316_mc_2AMi8o8xxxxxx_cdc.xe

From linux you can then run minicom -D /dev/ttyACM0 (or whatever your device is) or spin up Putty and add the new com port (you can identify it in device manager)

The files that have been added are:

Code: Select all

├── app_virtual_com_extended.h ​
├── app_virtual_com_extended.xc ​
├── cdc_descriptor_defs.h ​
├── xud_cdc.h ​
└── xud_cdc.xc 

But a few small changes were needed to lib_xua to get the endpoints connected up.

I'll talk internally about making this an appnote.
