[How to start with GUI Composer]

Malory Liban

Hello,

I am a beginer under CCSv5 and I have to develop an interface in order to control an electric motor and to see some parameters (current, speed, etc...) under CCSv5. I heard from GUI Composer so I started using it and I would like to know if there are an User Manual, or tips, or anything which could help me to begin with GUI Composer.

How to begin a project, customize Widgets, link with parameters from my CCS project and how to run the both of my project and the interface from GUI Composer.

I'd be grateful if you could help me in this matter.

    Hi Malory,

    When you open GUI Composer within CCS, the first thing you will see is the GUI Composer home page. There are two links, one to create a new project and the other one to import project. At the bottom of the page, you will see another link to open online articles, this link should bring you to the wiki page of GUI Composer. The wiki page contains information on how to get started, view the introductory video to get started with GUI Composer.

    Here is the link to the wiki page http://processors.wiki.ti.com/index.php/Category:Gui_Composer.

    Regards,
    Patrick

    Hello Patrick,

    Thank you for your answer. I find that the wiki page of GUI Composer is limited and explains basics operations only. So I would like to know if a "guide" as a pdf file does exist ?

    I would like a little piece af advice too. In my project (about electric motor), the parameter "Speed" is calculated in the file "SpeedEst.c" :

    temp->Speed = temp->Position - temp->OldPosition; // compute the motor speed

    For example, if I want to link a "digital gauge" to the "Speed" Parameter, Could you please tell me how do I have to fill in the blanks in the Binding parameters under Gui Composer ? I tried to write "Speed" in the Value field in the Widget Binding category in properties view, but it does not work.

    Thank you in advance

    Regards

    Malory

    Hi Malory,

    The wiki page is what we have right now. Did you get a chance to watch the video? You should be able to follow it to get you started.

    To bind the digital gauge with the variable that you have, try entering the fully qualified name of your variable (i.e temp->Speed), and this variable needs to be a global variable.

    Regards,

    Hello Patrick,

    Thank you for your answer. I managed to read (get value in time) 3 of my parameters. So with the widget scalarGraph, How can I grew up the acquisition of value ? In fact, If my parameter must look like a sinus curve (with 50hz frequency --> 20ms), I need to have enought points in 20ms from the acquisition in order to see the sinus correctly.

    So How to change the speed of the acquisition ?

    Thank in advance

    Regards

    Patrick,

    It works well, thank you. The acquisition allows to see parameters correctly. However, my computer does not seem fast enough. Performance seem inadequate because my fan runs constantly. I think the problem is my graphics card.

    Regards
