ulTaskEndTrace();

………..

Now I want this buffer tRace in some file, when I use normal method of File datatype in C

It generates error like .

Plz guide me ……………..


RE: Retrieving the trace buffer

Posted by Richard on March 1, 2008
You have no method of accessing files linked into your application - probably because you don't have a file system to which the data can be written.

Depending on your debug interface, it is normal to retrieve the raw data file through the debugger and save it to a file on your host computer.

Regards.
