USB Audio 2 software on a core-200 sliceKIT?

Postby keno » Thu Jul 12, 2018 4:09 pm

Hi Everyone. I just started on my first xmos project, and Im quite excited, but I may have started off with the wrong demo board.

Will the USB Audio 2.0 reference software run on a core-200 sliceKIT?
I bought a CORE-200 sliceKIT, with the hope of running some demo USB Audio 2.0 code. I now notice that this board is not listed as supported hardware, and none of the projects seem to work with this board. Am I selecting the wrong target in the makefile?
Did I buy the wrong board?
Is there usb audio 2.0 demo software for this board?
Which board should I buy?
Thanks

The slice kit is a generic platform where the I/O is specialised using slice cards.

There is no reason why you couldn't plug in an audio slice - https://www.digikey.co.uk/products/en?k ... A-SK-AUDIO

There will be some minor customisation (xn file, customdefines.h and audiohw.xc) but USB audio should run just fine with this combination. The customisation would be the same process as porting to your own board. It's not too hard and is described in section 5.6 of this document:

You could borrow the hardware setup code from app_usb_aud_skc_u16 which uses this card on the old XS1 slicekit..

oh, forgot to say, I'd start with app_usb_aud_xk_216_mc.. 2i10o10xxxxxx is the basic audio in/out only build

How many channels do you need and what other interfaces are on the list?

The audio slice card will do 4 in 4 out with MIDI and SPDIF output from memory
