Re: Why aren't my compile options working?
What george said is correct. You cannot trust xTimeComposer highlighting.

Re: Problem with XMOS Stereo driver and 32-bit
Hi. Disclaimer: Not an audio developer. Believe you may need to license the enhanced driver package from this company: https://www.thesycon.de/eng/usb_audiodriver.shtml Request their demo copy of the driver to validate this understanding. Fairly confident that other developers have had to follow th...

Re: Delay all cores from starting (xcore-200)
The par{} construct does not have be used in the main routine. Reference: http://www.xcore.com/viewtopic.php?t=3407 Can you shift the par construct to another core?

Delay all cores from starting (xcore-200)
Hi! I am trying to find a way to stall all the tasks/cores in the usb reference design from starting without rewriting too much of main().
