code generation using simulink

Hi, i am a university student. i am trying to generate a code for ccs4( for c2000 piccolo f28035 microcontroller). but whenever i try to generate , i get the following error "The left-hand side of a . operator must be a valid scope identifier".

i dont know what to do.kindly help.

regards, waqas

Support for CCS 4.0 was only recently added (I think it was R2011a). Also, you need to use the XMakefile configuration for CCS 4.0. If you are using a newer version of MATLAB, follow the steps on Tutorial: Using Makefiles with Code Composer Studio 4.x and see if that helps.

thanks for the reply. i tried as you mentioned but i am still getting the same error.can u suggest any other advice?

secondly,Kindly clarify me one thing,if possible, that " can i generate c code for the target device(f28035 in this case)without connecting the target device using simulink ". i am using matlab 2010b and ccs4 on windows7

Waqas: Like I mentioned before, CCS4 is only supported starting in R2011a - you might need to try with CCS3 if you are using R2010b. Try checking the "Generate code only" box in the Configuration Parameters window on the Code generation (previously Real-Time Workshop) pane: http://www.mathworks.com/help/releases/R2011b/toolbox/rtw/ref/bq259d4-1.html

thanks for your suppport but i still have the same problem.i updated to 2011a matlab, but still get the same error

"The left-hand side of a . operator must be a valid scope identifier"

I dont want to establish an ide link with simulink, all i want is to just generate a compatible code for ccs4.

i hope you can help me.

Waqas: Sorry, my experience with Embedded Coder and CCS is limited. Since you say that you recently upgraded, it means that you are currently on the MathWorks Software Maintenance Service. You should be able to contact MathWorks Tech Support and obtain help with this. I would recommend trying that out.

i am also trying to interface piccolo micro controller and i have followed the steps given but still it is showing could not build

Please help because i have tried it so many times

Siva: If you've already followed my advice to Waqas and still were not able to resolve the issue, you should probably contact MathWorks Tech Support.

I also had a hard time getting Matlab and Simulink to work with CCS. There is one good video that helped me start. I found it a bit long but it has all the steps needed, from installation to generating code for a simple Simulink model: It works for CCSv3.3 which is older but has automatic download and run from Matlab

The same video exists for CCSv4/5: http://youtu.be/7ed1NLD817s

I hope it helps.

Hi, is the video for CCS4 removed from youtube? it doesn't work.

I also face the same problem.I am using CCSV3.3.What should I do now?
