In external mode, you must first create an executable target application. The Simulink® Coder™ code generation software creates C code from your Simulink model. The bundled C compiler compiles and links that C code into a real-time application.
This procedure uses the model
(matlab: open_system(docpath(fullfile(docroot, 'toolbox', 'sldrt', 'examples', 'sldrtex_model')))). It assumes that you have already loaded that model.
In the Simulink Editor, from the Apps tab, click Desktop Real-Time.
This operation select configuration parameters for use by the Simulink Coder code generation software. See Set External Mode Code Generation Parameters.
On the Desktop Real-Time tab, click Run in Real Time.
Coder code generation software creates the C code source files
The build process creates the makefile
from the template makefile
The build process creates the real-time application by using
sldrtex_model.mk. On Windows®, the build process creates the binary file
sldrtex_model.rxw64. On Mac OS, it creates the binary file
The binary file
sldrtex_model.rx*64 is referred to as a
real-time application. You can run the real-time application with the
Desktop Real-Time™ kernel.
After you create a real-time application, you can exit MATLAB®, and restart MATLAB again, and then connect and run the executable without rebuilding your code. For more information, see Execute Real-Time Application in External Mode by Using Step by Step Commands.
