MATLAB: Tlc file for level 2 s function

Embedded Codersimulinksimulink codertlcxpc

Is there a simple documentation with a step-by-step tutorial on how to create a tlc file for a level 2 s function? It's a pity that such a file is not created automatically for xPC target!

Best Answer

You can find some simple example of in-lining level 2 s-function here

Inlining MATLAB File S-Functions, Block TLC beginners guide, TLC :Quick start guide

Here you will find the quick reference of overall code generation architecture using TLC.

Also see some available custom blocksets like Arduino blockset, and see how blocks and their TLCs are implemented.

Start with basic examples and use TLC user guide for reference.

The code:

slConfigUISetVal(hDlg, hSrc, 'ModelReferenceCompliant', 'on');
slConfigUISetEnabled(hDlg, hSrc, 'ModelReferenceCompliant', false);
slConfigUISetVal(hDlg, hSrc, 'ParMdlRefBuildCompliant', 'on');
slConfigUISetEnabled(hDlg, hSrc, 'ParMdlRefBuildCompliant', false);

Should be defined in a separate MATLAB file named custom_select_callback_handler.m that should be present on the MATLAB path:

function custom_select_callback_handler(hDlg, hSrc)
slConfigUISetVal(hDlg, hSrc, 'ModelReferenceCompliant', 'on');
slConfigUISetEnabled(hDlg, hSrc, 'ModelReferenceCompliant', false);
slConfigUISetVal(hDlg, hSrc, 'ParMdlRefBuildCompliant', 'on');
slConfigUISetEnabled(hDlg, hSrc, 'ParMdlRefBuildCompliant', false);

MATLAB: Do I receive an error when using the serial communication blocks for xPC Target 2.6.1 (R14SP1) with Model Reference

The blocks that control RS-232 communication with the xPC Target are implemented with S-functions. S-functions are a feature of Simulink that allow you to incorporate code in several different programming languages, such as C, M, and Fortran.

When you use Real-Time Workshop to generate code from a block diagram with S-functions, you can inline them. This incorporates the C source of the S-function with the C source generated by Real-Time Workshop. This eliminates the need to refer to an external C source file for the S-function. This inlining process is controlled by the Target Language Compiler (TLC) files.

The Model Reference functionality has a limitation in that it only supports S-functions that can be inlined, or those that have TLC files. The xPC Target RS-232 communication blocks do not currently support inlining.

To work around this, keep all the communication blocks in the top model and add additional ports to your referenced model to allow it to pass communications to these blocks.
