Setting up Graph Window with GEL on CCS5?

Todd Anderson78572

All:

I know that you can add sliders for variables using GEL scripts.

Can the same type of GEL script be used to create a graph of data stored in a buffer?

Present instructions regarding graph window:

From the CCS Debug View, Tools-->Graph-->Single Time  will bring up the following window. There are 4 values that need to be changed from the default values:

   Acquisition Buffer Size – change to the size of the buffer = 4000

   Dsp Data Type – change to 16 bit signed integer

  Start Address – the address of the buffer:  0x20000

  Display Data Size – again, change to the size of the buffer = 4000.

 

I would like to be able to do the above from a MyFunctions pull-down menu:

MyFunctions-->Graph_Waveform

    Hi Todd,

    Tweaking the graph is not possible via GEL or DSS. You can probably do this via GUI scripting which is not officially supported. The best would be to have a console command to do this. I don't think one exists but I can file a request for you.

    Thanks

    Ki:

    Thanks for your email. Yes, I think adding a console command would be a good thing.

    The CCS graphing feature has been a real time-saver for the product that I have been working on. It allowed me to display 32-bit data gathered from a buffer, and gave some immediate feedback to the code that was written.

    Hi Todd,

    There is a scripting console command called 'openAnalysisView' that may be what you are looking for. You can open a graph and import a graph properties file. The graph properties file would have the properties for your graph and importing it would restore the properties.

    js:> help openAnalysisView

    Description: opens an Analysis View.  E.g. to open a single time graph, openAnalysisView('Single Time','C:\\abc.graphProp')
    Syntax: openAnalysisView(viewID,arg)
    Arguments:
      viewID - Name of the view. Please see feature specific view names For CCS Graphs Feature: 'Single Time', 'Dual Time',  'FFT Magnitude', 'FFT Magnitude Phase', 'Complex FFT', 'FFT Waterfall'
      arg - See feature specific interpretation of this argument For CCS Graphs: Used as a property file from which to load the graph property values

    Does this mean we can't save a graph as a component in a screen lay-out after we have set one up, by saving it in a perspective? It seems like we should be able to do this, yet I have not managed to.
