Re: DFU questions

Hi cps
I had a disk crash which had all my XMOS stuff on it & haven't gone back to it
You can get this .bin file yourself if you follow the instructions, no?

Re: About xCORE200 extending the reference design to higher sample rates

Is it just a matter of changing the bit mask in Audio_XC ? I am not 100% sure because we have never pushed it that far (for xCORE200 or XS1). I believe others have tried and succeeded though. It's certainly the first thing to do. I recommend putting some prints in there (enable xscope for that othe...

Re: About xCORE200 extending the reference design to higher sample rates

Can I ask a different but related question? I know DSD samples are composed of High sample or Low sample - a sample being the duration of X number of master clock cycles. In other words a DSD64 high sample is high for 8 clock cycles. I wanted to be able to change all the High DSD64 samples to high f...

Re: AN00231 SPDIF-Receive-to-I2S-output-using-ASRC x->192kHz

OK, thanks, ff
XU216 has 16 cores so that's fine
3 timers ? Are these not assigned by the ASRC software or do you mean 3 oscillators?
12+ channels? Can you explain this please?

Re: AN00231 SPDIF-Receive-to-I2S-output-using-ASRC x->192kHz

So on a XU216 SPDIF input with 2*resampling or the default 3* will work fine with the existing libraries or is 192KHz output out of bounds?
ffomich, did you get any further on this?
I saw your other thread (July) on this - are you using the 2*SPDIFreceiver() here?

Re: XCORE-200 VBUS

What ripple & Freq was on the Vbus line that damaged the XMOS chip?

Re: XCORE-200 VBUS

I don't wish to drag this OT but can you say where in the software that Vbus is referenced?
I'd like to investigate the possibility of avoiding the need for this Vbus sensing - some other USB receivers on other chips (ARM) don't appear to need Vbus sensing

Thanks Larry, I missed this post somehow - good info.
