Code Composer V4 - Graph problem...

John Miller58692

Hi everyone,

this question regards problems with plotting graphs in CCS V3 and CCS V4 for  TMS F2808 eZdsp board I have a hand-made inverter for AC induction motor control... I made my software in CCS3 using ACI 3_1 tutorial as a starting point and it worked just fine. But, I had a problem with exporting graphs to other documents (Word, Matlab, etc). The only way it worked was by using ALT+PRNTSCN...

Now, I switched to CCS V4 just to export graphs. After a time of hopeless migrating process, i quit, and re-made my model again in CCS V4. It works fine, I can see variables in Watch Window and controll the project, but I still can' t plot graphs. My graphs are meaningles... Even try to plot a constant (Torque_Ref in Q24), but all I got is a bunch of broken lines...

Where am I wrong?

Is there any tutorial like ACI3_1, ACI3-4 or made in CCS V4 with graphs that works fine. I found a lot of such demos for Piccolo series, but did TI stop improving its tutorials for 2808 in Code Composer V4???

Regards,

Miller

    John,

    I'm sorry you're having a frustrating time with graphs.

    In CCS 3 you can export data using   file->data save and then specifying the memory range you wanted to save.  The first line will be some information about the start address/length that you can delete.  The rest will be the memory contents - one value per line.

    I'm going to move this thread to the Code Composer Forum so the experts there can comment.  One suggestion I have is to make sure you have 4.1.3 or later - there were a number of fixes for C2000 in that version.
