TMS320F28379D: Using CCP with Simulink and CANape

Part Number: TMS320F28379D

Hello,

I have problems to make a CCP interface running on a TMS320F28379D Launchpad.

I use Matlab Simulink 2018b for generating the code.

I tried several configuration and followed the mathworks documentation step by step:

https://e2e.ti.com/support/microcontrollers/c2000/f/171/p/929803/3435512?tisearch=e2e-sitesearch&keymatch=canape#3435512

https://de.mathworks.com/help/supportpkg/texasinstrumentsc2000/ug/external-mode.html#bups63k

I think my problem is that no DAQ_LIST_EVENT_MAPPINGS file is generated while building the code.

I am using canlib.Parameters and canlib.Signals as Exported Global storage type. Data type uint16.

However I have no clue why the mathworks example model c28x_ccp_ert generates the list and my model not.

Has anyone more ideas what to try or check?

The further target is to use CANape to control the DSP via CCP.

Regards

Paul

Paul,

Like hareesh mentioned earlier, if this is something to do with our device we can help out. You may need to reach out to mathworks on this.

I will request our folks to look at it again, but this mostly looks to be a mathworks specific problem.

Hello Paul,

Did you review our documentation on CCP for C2000?

https://www.mathworks.com/help/supportpkg/texasinstrumentsc2000/ref/c28xcancalibrationprotocol.html?s_tid=srchtitle

If you did and are still stuck, you should contact MathWorks Technical Support for assistance. My quick guess is that you have something not configured correctly, but I have no idea where.

Thanks,

-Brian

Thanks Brian,

I already read your linked articles.

But, I also made some small progress:
With the settings from the mathworks example model c28x_ccp_ert the daq list is generated.

I wonder if the by mathworks recommended general settings (storage type Exported Global) are just for ccp polling?

For me works: (external Mode Simulink)

canlib.Signal, Storage class: Daq_List_Signal_Processing (Custom)

tic2000demospkg.Parameter, Storage class: const_data_ramfuncs (Custom)

Also I am in contact with Mathworks technical support.

Regards

Paul

HI Paul,

I don't have any real technical expertise with CCP, so I cant answer the detailed technical question.

Please continue to work with MathWorks Technical Support, as they can escalate to MathWorks Advanced Support or Development Team as needed.

Cheers,

-Brian

Paul,

As mentioned earlier, we are happy to help with issues related to the CAN module itself, but regret we are unable to support CCP.
