XK-AUDIO-216-MC-AB availability?

I see that XK-AUDIO-216-MC-AB (xCore-200 Multichannel Audio) is out with no lead time at Digi-Key, and Farnell is showing back in stock on May 2018. What is the production status of this board?

Re: Xconnect Xlink / Link Problem

Don't despair -- some of us have got it working! This is an off-label use of Xconnect, so support can unfortunately be a bit light. In fact there's much more documentation than there used to be. I'm out of guesses, so I'll try this out on my hardware (I have a setup for running this demo, as it happ...

Re: Xconnect Xlink / Link Problem

If this is the only code you changed, I suspect that the control token is somehow coming through at the wrong time. This might not be caught by testct because testct only checks the next byte. What happens if you comment out the outct in the transmit part? By the way, I'm afraid I steered you a bit ...

Re: Xconnect Xlink / Link Problem

Did you also change the receiving end to receive integers, using inuint?

Re: Xconnect Xlink / Link Problem

Chanends can transmit any type at any time; they do not have to be set up to send a specific type. There is no special initialization to do to make a chanend transmit a 32-bit integer, for instance. You can use a chanend to transmit a 32-bit integer, and in the next instruction use it to transmit an...

Re: Xconnect Xlink / Link Problem

The ET_ILLEGAL_RESOURCE exception in this case may indicate that there is something wrong with the chanend variable. Make sure that it is properly initialised. Also, when using statically-routed chanends as is done in the demo, you will usually not have much luck with the input and output operators,...

Re: how set USB tile?

Not an official XMOS answer here but -- The USB peripheral is configured over Xlink. On XS2 devices, either tile can use it, though in practice only one tile should try to use it at a time. (On XS1 devices like XS1-U16A, only one tile can physically use the USB peripheral; there is no choice given.)...

Re: XHRA-2HPA USB power detection

Regarding capacitors -- I too try to use ceramic wherever possible, and I have not designed tantalum caps into anything for many years; I am not aware of any compelling advantages they offer over modern multilayer ceramics, at least for what I do (audio mostly). Unfortunately, in audio signal paths,...
