Compiling M files for dSpace

Hi,

I have implemented some controllers for my electrical ciruit using m files, when I tried to compile it or use with dSpace, I get the error message as follows:

*Error building Real-Time Workshop target for block diagram 'GridConnectedDSP'. MATLAB error message: Error using ==> tlc_new Error: File: C:\Program Files\MATLAB\R2008a\rtw\c\tlc\lib\utillib.tlc Line: 461 Column: 8 %exit directive: Real-Time Workshop Fatal in block: "GridConnectedDSP/Controller/Controller", block type "S-Function": MFile S-functions without a corresponding TLC file are not supported. You can inline your S-function (TKT_VIDG2U) by creating a TLC file for it. You can also remap your S-function to C by creating a corresponding C Mex source file and a TKT_VIDG2U.tlc file in the same directory as the MFile S-function which contains (on the first line): %% CallAsCMexLevel1 or %% CallAsCMexLevel2*

Is there a way to solve this problem? Really desperately looking for help. Thank in advance!

I don't know if this 2002 discussion is still relevant, but possibly you just can't do that: see this

It is difficult to find useful information about dSpace on the Mathworks web site.

The message you are encountering means that somewhere in there you have a Level-2 S function that you are trying to generate code for, OR you are trying to generate code for a Simulink block that they did not provide compilation information for. In order to generate code for the missing piece, you have to provide a Target Language Compiler file.

As Walter suggested, you can't generate C code from a MATLAB S-Function without writing a TLC file. See Generating Code from a Level-2 MATLAB S-Function in the Simulink documentation.

I would recommend using an Embedded MATLAB Function (now simply called a MATLAB Function in R2011a) instead, but you will need to restrict your code to using Functions Supported for Code Generation.

HTH,

Hi all, is there a way then to change my code or write the TLC files for my program? I am really at a loss. Thanks a lot for all the kind advices.

Either write your S-function in C or use an Embedded MATLAB Function as I suggested. My recommendation would be the latter.
