XMOS-based Asynchronous USB to I2S interface

[Lorien]

I'm glad that it's solved! For shorter I2S connections though, you can place your WaveIO as closest to your DAC as possible and switch it to external USB (J8=EXT) by using an adapter like this one.
Cheers,

external usb (with a usb cable I'm crafting) and external power are two future steps in search of improvement.
At that point I'll turn WaveIO 90° counterclockwise and I2S cable will be less than 10mm.
Just a hint for whoever need a connector for isolated pins at nearly no cost: an old ide connector

Thanks hochopeper for answering correctly. I am exploring digital sides of WaveIO and WM8740 but have yet to connect. There is no DPC latency issue on any of my computers except the eeePC portable. I am writing a small Windows dialog app to control the Diolan->WM874x register interface. It will also respond to http gets with a tiny webpage for the Palm Tungsten so I will have volume, balance, and mute thru wi-fi. Tungsten C was shipped with a web browser and wi-fi and I just received one for US$6.14 shipped

Hi Lucian

i've just build a Teleporter Buffalo III to try with Your board connected frpm PC with .5M Wireworld Ultraviolet cable.

WAVEIO into Buffalo III sounds just sublime

thanks again for the great board

take care

Hi Lorean

A quick question. Is it possible to connect between a pc and the usb to i2s interface via wifi or wireless bridge by using some kinda of usb to wireless adapter ?

[hochopeper]

quick answer is: No. No such device exists to my knowledge.

You may be able to have a low powered computer local to the WaveIO device and connect to storage somewhere else on the network though that adds a layer of complexity I think you're trying to avoid ...

you know that screw terminal will be decimating any impedance matching you achieve with those u.fl cables right? its completely possible to turn that input into a bank of 4 x u.fl

There's a project somewhere that allows usb over ethernet, I think the host has to be linux but I could be wrong. An old thin client or something like a beagle board would be more than sufficient. But you could also turn that old thin client into a squeezebox/mpd-server/etc.

How would one do that? Thanks.

I should receive soon these parts to compare the isolated I2S output with coax outputs
