DRV8301: "Universal" GUI doesn't work

Part Number: DRV8301
Other Parts Discussed in Thread: MOTORWARE

Hello,

I recently downloaded the Universal GUI for instaSPIN. Before installing, it asked me whether I wanted to Uninstall the previous version of the GUI (bought this kit about 4 years ago - finally using it), and I answered "yes". The installation got hung up, so I eventually hit the "Cancel" button. Tried running it anyway and saw a really ugly GUI. So, I figured I'd re-install it, but to save some time I'd run the uninstallers in the gui composer folder. They are 'uninstall_ti_dspack.exe' and 'uninstall_ti_emupack_5.1.641.0.exe'. I reinstalled the Universal GUI program (successfully this time), but I still have the ugly GUI. The following messages appear on the Configuration page:

Restarting Program Model...
Initializing target : C:\ti\guicomposer\eclipse\workspace\.metadata\.plugins\com.ti.binding.program\appConfig.ccxml
Loading program: null
sun.org.mozilla.javascript.internal.WrappedException: Wrapped java.lang.NullPointerException (<Unknown source>#18) in <Unknown source> at line number 18Restart Completed.

I've attached a Screenshot of the GUI.

Any ideas what I might need to do to get this running?

Thanks,

Dave Reagan

    Dave,

    Can you please uninstall all instances of this GUI and GUI Composer?

    Search your Program Files directories and delete those directories as well please.

    Then install from fresh.

    Regards,

    Hi Adam,

    Tried uninstalling and re-installing once already, but I didn't look through the Program Files directory. Thanks for the advice.

    Hi Adam,

    Nah.. it's still exactly the same GUI, with all the components x'ed out. Here are the messages on the Configuration page:

    Restarting Program Model...
    Initializing target : C:\ti\guicomposer\eclipse\workspace\.metadata\.plugins\com.ti.binding.program\appConfig.ccxml
    Loading program: null
    sun.org.mozilla.javascript.internal.WrappedException: Wrapped java.lang.NullPointerException (<Unknown source>#18) in <Unknown source> at line number 18Restart Completed.

    Thanks,

    Hi Adam,
    Here are the links you requested:

    www.ti.com/.../DRV8301-HC-C2-KIT

    www.ti.com/.../INSTASPINUNIVERSALGUI

    As I said above, I bought this kit about 4 yrs ago. The project I was working on got cancelled, so I never had much chance to check it out. The project has since been revived, so now I'm looking at instaSPIN again. I upgrade Code Composer to the most recent version (8.something), and I have motorware_1_01_00_18 existing alongside motorware_1_01_00_14, though in a separate folder. Originally, I had the InstaSPIN FOC and instaSPIN Motion GUIs on this machine. When I tried to install the Universal GUI, I was asked whether I wanted to uninstall the existing GUIs. I answered "yes". Maybe I shouldn't have. Maybe there are some supporting files, that are now missing as a result. I'll try uninstalling the universal GUI again, reinstalling the original two I had (if I can find them), then reinstalling the universal.
    Thanks,
    Dave

    the components are x'd out because you aren't connected to a target that has those variables in the binary.
    I'm guessing you don't have an appProgram.out in the folder at all?

    the Universal GUI is to be used with a compiled MotorWare (pref v18) project.

    There is a UG here
    C:\ti\motorware\motorware_1_01_00_18\docs\guis\universal

    which explains that you can use the Universal GUI inside CCS, or create a .out inside of CCS, move it to the Universal GUI folder, and rename to appProgram.out so that it auto loads this .out when you run the GUI standalone.

    Hi Chris,

    Thanks. That was it. The ReadMe Tab has instructions stating:

    "To use the GUI .exe, the compiled .out must be copied to the webapp folder, ex: C:\ti\guicomposer\webapps\InstaSPIN_F2802xM_UNIVERSAL\appProgram.out"

    I didn't realize the "appProgram.out" was meant to be taken literally (i.e. you have to rename the file).

    Thanks again, and

    Best Regards,

    Dave Reagan
