Using CCstudio graphs

Other Parts Discussed in Thread: CCSTUDIO

Hello I am trying to run an adapted version of the FOC motor control library on an F2833 controller.(The library was originally written for the F280x controller). I am working with the manual for this example and doing the incremental build. Right now I am at Phase 4.1a, to test the SVGEN_DQ module. This is a module to create the Ta, Tb, Tc signals.

I would like to see the signals in the CC graphs which I set up exactly like described in the documentation of this particular module. Unfortunately the signals I see are completely strange and have nothing to do with the signal I should see. Strangely the real PWM Output signals of the controller are looking OK on the oscilloscope. So my conclusion is that the Signals, which comes out of the SVGEN_DQ module are also OK. But why is the graph so strange?. I tried to watch other modules with the CC graphs like the Output of the RAMP_GEN module. I should see a ramp function. But this signals are also completely strange. Can anybody help me here since nobody in this lab worked with 
CCstudio before and I am a student working for the first time with it. Thanks for your help. Maybe I can post the code to an email address?
  • I just found out: If I use the DatalogModule in connection with the RampGen module I get a ramp function in the graph window. But I still don`t get the wanted waveform if I connect the Outputs of the SVGen module to the DataLogModule...same problem as before!

  • Which manual are you referencing?

    Also, would you be able to provide the literature number for the software you are using?

  • Here are the data which I found in Code Composer Studio/help/about:

    Code Composer Studio 3.3.59.4 ; Integrated Development 5.98.0.339; BIOS 5.32; Code Generation Tool v.5.0.0B2; Board Revision 00.00.84; Target Silicon Revision 00.00.02

    I am using the motor control library for the 280x:  PMSM3-1 and I am referring to the manual, provided with it. The literature number should be SPRC210.

    The data graph function in Code Composer Studio is still now working. As I said I can see the ramp function but the values of the x and y coordinate are much to small. I tried to calculate the time in [us]

    by using the x coordinate values, shown in samples. By doing that I get an reasonable result. But if I select to show this axis in [us] or [s] the values are much to small and doesn`t make any sense.
