Real-Time Windows Target

Files on the Your Computer

When using the Real-Time Windows Target, you may find it helpful to know where files are located:

• MATLAB working directory -- Simulink models (model.mdl) and the Real-Time Windows Target executable (model.rwd)

• Note Select a working directory outside of the MATLAB root. See Initial Working Directory.

• Real-Time Workshop project directory -- The Real-Time Workshop C-code files (model.c, model.h) are in a subdirectory called model_rtwin.

Real-Time Windows Target Files -- The files included with the Real-Time Windows Target are located in the directory

• matlabroot\toolbox\rtw\targets\rtwin
  

The Real-Time Windows Target provides files to help Real-Time Workshop generate C code from your Simulink model, and compile that code to a real-time executable:

• System Target File (rtwin.tlc) -- Defines the process of generating C code for the Real-Time Windows Target.
• Template Makefile and Makefile (rtwintmf.m, model_name.mk) -- The template makefile serves as a template for generating the real makefile, which the make utility uses during model compilation. During the automatic build procedure, the make command extracts information from the template makefile rtwintmf.m and generates the makefile model_name.mk.
• Make Command (make_rtw.m) -- The standard make command supplied with Real-Time Workshop.

Other files provided with the Real-Time Windows Target include

• I/O drivers (*rwd) -- Binaries for I/O device drivers. The Real-Time Windows Target does not link the driver object files with your real-time executable. The drivers are loaded into memory and run by the kernel separately.
• Simulink external mode interface (rtwinext.dll) -- MEX-file for communicating between Simulink external mode and the Real-Time Windows Target kernel.

• Simulink external mode uses the MEX-file interface module to download new parameter values to the real-time model and to retrieve signals from the real-time model. You can display these signals in Simulink Scope blocks.

• Kernel install and uninstall commands (rtwintgt.m, rtwho.m) -- M-file scripts to install and uninstall the Real-Time Windows Target kernel and check installation.
