Re: Parsing .xmt files from XSCOPE?

Update: sampling rate looks good now, it was an issue in my parsing script. Thanks again for the help Matt, and I'm happy to post my xmt parsing script if it would be helpful to anyone, although it's pretty slow (about 2 min for 1 million lines).

Re: Parsing .xmt files from XSCOPE?

Perfect, changing this in xscope_register fixed the issue. Thanks Matt!

Now that this is working I have a questions about sampling rate (Sampling rate for my code is 48000, but Xscope only seems to be getting samples at half this rate), I'll start a new thread for this.

Re: Parsing .xmt files from XSCOPE?

Quick update: I just tested with a different, non-audio signal from my code, and the offline scope works great, seems to be something unique to the audio signals I'm streaming in.

In my header: #include <xscope.h> void xscope_user_init(void); in my .xc file: #include "feedbackDestroyer.h" void xscope_user_init(void){ xscope_register(4, XSCOPE_CONTINUOUS , " Channel 0 " , XSCOPE_UINT , " mV ", XSCOPE_CONTINUOUS , " Channel 1 " , XSCOPE_U...

Re: Parsing .xmt files from XSCOPE?

Thank Matt. I'm actually seeing the same behavior in xtimecomposer, but only in the Offline Scope. I've attached to shots of the same signal, one in real time, one offline. Any ideas here? I'm using xtimecomposer v13.

Parsing .xmt files from XSCOPE?

It would be very helpful to my workflow to capture streams from XMOS directly to my computer (in a .txt or whatever). XSCOPE seems like a slick way to do this, so I wrote a quick python script to parse .xmt files from the scope. A typical Record line from the .xmt file looks like this: <Record Type=...

XMOS Development Workflow Tips?

I'm getting to a point in my XMOS development where code complexity and organization are becoming big issues. My general algorithm development strategy begins in Octave/MATLAB, where I do the majority of my testing and tuning, and then generally implement on XMOS after I'm happy with the results. I ...
