The Usb Audio 2.0 Dj Kit (U-Series) - XMOS xCORE-200 Multi-channel Audio board Design Manual

USB Audio Design Guide
This configuration can be achieved by in the Makefile by defining SPDIF_TX as zero:
- DSPDIF_TX =0
and MIDI as 1:
- DMIDI =1
6.1.4.3 Configuration 1ioxs
This configuration is similar to the first configuration apart from it runs in Audio
1.0 over full-speed USB.
This is achieved in the Makefile by:
- DAUDIO_CLASS =1

6.2 The USB Audio 2.0 DJ Kit (U-Series)

The USB Audio 2.0 Reference Design is an application of the USB audio framework
specifically for the hardware described in
single tile device (500MIPS). The software design supports four channels of audio
at sample frequencies up to 192kHz and uses the following components:
XMOS USB Device Driver (XUD)
Endpoint 0
Endpoint buffer
Decoupler
Audio Driver
Device Firmware Upgrade (DFU)
S/PDIF Transmitter or MIDI
The software layout is the identical to the single tile L-Series Reference Design and
therefore the diagrams Figure
code running on the XS1-U chip.
As with the L-Series, each unit runs in a single core concurrently with the others
units.
Due to the MIPS requirement of the USB driver (see §3.14), only six cores can be
run on the single tile L-Series device so only one of S/PDIF transmit or MIDI can be
supported.
