BQSTUDIO: BQSTUDIO

Part Number: BQSTUDIO

Hello TI Team,

I found that in bqStudio, there are Log, Watch and Data Graph functions to monitor SMBus registers' status. They looks like very similar. I'm wondering if there is any difference regarding SMBus reading? Or which one is more preferred for testing?

Thanks,

Zhihan

    Hi Zhihan,

    The log feature is the most used. When the log is captured, you can easily plot the data in any tool you prefer. Logging is very useful for longer experiments and can be very helpful to understand how the status registers are changing throughout the experiment. The Watch and Graph functions are useful for real time monitoring. The watch will just display the current value of the selected registers and the Graph will give you a visual representation.

    They are all useful depending on what type of experiment you are doing.

    Best regards,

    Matt

    Hi Matt,

    Thank you very much for your explanation!

    I found that I can output Watch data similar to Log data. And for Log, I can select only the registers I want. In this case, Watch seems the same as Log. So just curious why there are 2 very similar functions?

    And for Data Graph, I found only 1000 points of data can be shown. Is there any way to show more data?

    Regards,

    Zhihan

    Hi Zhihan,

    Yes, Logging and Watch are very similar. Watch allows you to see the data live where Logging will record the data to a file you can view later. I personally use the logging feature much more often - you can use it to run long-term experiments and then view and plot the data later.

    To increase the number of point for the Data Graph, select from the Window->Preferences->Data Graph menu. Here you can change to the number you want. There are many other option in the Preferences menu you can modify. For example, under the Registers menu, you can change the logging interval. 

    Best regards,

    Matt

    Hi Matt,

    Thank you very much for your tips! I will try on Preferences menu myself.

    Also you mentioned "data live". So I tried on Log and Watch a little bit. I found say interval is 2s, when Log is used, Register tab are not updated per 2s, but for Watch, the selected registers are updated per 2s. Are these the "live" you mentioned? And I guess "live" only happens for Watch, Data Graph, and Scan?

    Thanks,

    Zhihan

    Watch displays the data to the screen while Logging records it to a file. Logging is also "live" it is just not displayed to the BQStudio window.
