CCS: GUI Composer Problem

Mike Dalby
Intellectual 420 points

Tool/software: Code Composer Studio

Hi All

I am trying to get the simple GUI composer demo working with my eval board (MPS-EXPFR5994) but am failing miserably (I been on this for hours now and tried lots of different combinations).

The demo I am trying to follow is on Ti's Youtube channel

The demo is pretty simple - just a blinking LED and a GUI element that follows its value (on or off).

My MPS-EXPFR5994 eval board works fine and I can use the cloud version of the CCS to create, program and debug this very simple flashing led -  note that I have created a global variable as detailed in the demo:     'int ledStatus =0;' to act as the link between my program and the GUI Composer.

Where the current version of the GUI composer and the youtube video differ is during the configuration/setup phase. In the video the guy chooses XDS as the connection method and then he gets a connection method for the XDS110 USB debug probe:

When I do it in the current version of GUI composer I get a choice of 'Program or Register:

If I choose program, then I get some other boxes to fill in 

I have tried lots of different method/selections in these setup methods, but nothing seems to allow me to connect the LED GUI form item and display its value (as described in the remainder of the youtube video). 

I have tried to read the help documentation with regards to the GUI composer but all of the reference material is out of date and does not refer to any of the available menu selections/fill-ins that are in the current version of the GUI composer. 

I know my GUI composer project is talking to the board in some way as it programs the board with the 'out' file when I refresh the Chrome browser 

I hope someone can suggest some help

Cheers

Michael

    Hi Michael,

    The youtube video is based on an earlier version of GUI Composer, you should be able to find documentation on GUI Composer by clicking on the Getting Started link in the 'Welcome to GUI Composer' dialog. You can also get to the Getting Started from Help | Online Help... menu item. At the bottom of the Getting Started page, there are tutorials. These tutorials are upto date with the latest GUI Composer.

    Your device is different than the youtube video (MSP432) in the communication protocol. The MSP432 supports realtime access with XDS communication protocol, MSP430 does not. So, you can't use XDS with GUI Composer for MSP430. However, you should be able to follow the USB-UART tutorial to send JSON data from the device to the host PC. Direct link to the UART tutorial https://dev.ti.com/gc/designer/help/Tutorials/Serial/index.html

    Regards,
    Patrick

    Michael,

    Interesting; it seems there was an interface change between the date the clip was released and the latest version of the GUI Composer.

    The procedure I followed is slightly different and shown below for the MSP432P401R launchpad:

    For a MSP430 board, I followed the same procedure, only selecting a TI MSP430 USB1 interface in the Connection drop-down of the New Project Wizard. 

    I apologize for the confusion,

    Rafael
