saving values from watch window while code composer is running

Hi All

My 28069 prcosseor is excuting a FFT code on the input waveform. However, due to many output (128 point FFt 128 point output values) I prefer to collect the data online and then anlayis the result offline. The code composer watch varibles are refreshed each few seconds. I am trying to find a way to save the FFT values while the code is running into a txt format. Then I will have the results for many different instances. Finally, I can take a look at txt files and analysis the results.

Is it possible to do that in code composer?

Why cant you define reserve memory where you can dump these variables and then at the end you can dump it to file?

Other option is (if performance is not critical), you can print those values to console and in CCS setting you can give an option to save CIO.

Another option may be to set a breakpoint at a source line after the variable of interest is updated, and under Breakpoint Properties, set the action to "Write data to file" instead of "Remain Halted". Then every time the breakpoint is hit, instead of halting the target, the value of the variable will be written to a file, and the program will continue to run. An overview of this feature can be found in this wiki page: http://processors.wiki.ti.com/index.php/GSG:Debugging_projects_v5#Managing_breakpoints
