CCS/UCD90120A: Variations in encoded commands through TI Power Digital Designer

Tool/software: Code Composer Studio

Hi,

I've recently been tasked to build a project file from scratch showing that the file we intend on using can be built in the future if we ever need to. There are no issues when I create a copy but when I look at the file compare tool I see various discrepancies between what I have and what was built. For most, it's pretty obvious since the new file has never seen hardware and the status registers obviously don't have any detail but for some I'm scratching my head. I'm hoping to get some clarity on why the hard coded values might be different for the same exact variable. See the following:

Also, I am unsure what this command is used for and what feature is used to configure this command within the GUI.

Thanks,

Jordan S.

    looks like my pictures didn't make it into the post.. attaching the file compare export.

    Any of the rows that have red fill next to them have discrepancies between the text description and the hex values that are sent. I would like to understand why there is a difference between the two.

    Hello

    Many thresholds are encoded with LINEAR11 format. For a given value, for example 0: both 0x8000 or 0x0000. If GUI has both displayed as correct decoded value, you can ignore  those differences.

    Now, You only have the following items:

    OPERATION(line 18) is runtime value and not part of the configuration, you can ignore. 

    line 48 is kind of interesting. Are you sure that you do not change this?

    line 52 you can ignore those differences since they do not impact anything.

    line 57, you can also ignore this since they do not impact anything

    It seems that your original project file was generated from very old fusion GUI and you may use newer GUI to import so that there are many differences. 

    if you want to understand all these, please refer https://www.ti.com/lit/ug/slvuaw9c/slvuaw9c.pdf which has details about each command.

    Hi Yihe,

    Thank you for the quick reply. This has resolved the issue

    As for line 48 it does appear to be a mistake on my end.

    Thanks,

    Jordan S.
