GUI Composer Data Logging

Hello,

Is there any way to log datas on a file with code composer studio?

Can you provide more details on your use case? For example, are you looking to periodically log the value of a variable for a program running in the target? Are you looking to do this non-intusively (not halting the target)? What target are you using?

Thanks

I am using my own board with TMS320F28069M mounted. I want to log a variable for a program running on that mcu. I will not halt the target.

Do you need to variable logged at a specific interval? 

yes exactly, I need to log some variables logged at specific interval.

What is the frequency? If it is at a very high rate, then it may not be possible with an existing setup.

10kHz is enough. Is it possible to log a variable at 10 kHz? At that frequency at most how many variables can i log at that frequency?

That is a challenge and not possible without doing some buffering on the target and the reading the data out in larger chunks at a less frequent interval. When I have done some tests on 28x trying to read/log variables in real-time to the host, the best I was able to do was ~100 Hz. There is some overhead in each read attempt hence better to read larger chunks less frequently.

Ok then do you mean that I need to put the value of variable on a buffer array at each 100Hz interval and work on those logged array then?

If so, how can I do that?
