Creating a standalone .exe of an .m file that calls a simulink model
Hi,
I have a .m file that controls a gui. A slider in the gui is used as input for a simulink model. My goal is to create a standalone of this whole application, that runs on a PC where neither Matlab nor Simulink are installed.
My approach so far is to generate a standalone .exe out of the simulink model, modify the .m script to pass the input values to this .exe and get the output values, and then generate a .exe out of the .m script.
I have several questions on how to do this:
# Is this the correct approach or would it be better to create a dll out of the simulink model?
# If this is the way to go, which target in the code generation allows the easiest passing of values to the simulink model .exe? I found three different options: ert_shrlib (host based shared library), grt (Generic Realtime Target) and rsim (Rapid Simulation Target). Which of these should I use?
# Are there any step-by-step instructions on how to accomplish this? Or even examples of a similar project?
Thanks you very much!Hi,

TI C2000 : In Simulink, how to set ePWM output to a GPIO pin ?
Hi Sir,
I am using TI C2000 processor(TMS320F28335), and had just placed an ePWM module into the Simulink and set some parameters.
(I guess C2833x is for TMS320F28335, am I correct ?)
now I want to set the ePWM output to a GPIO pin, but under "Hardware setting" -> "Hardware Implementation" -> "Target hardware resource"->"ePWM", there is no relevant settings for GPIO
On the other hand, refer to : www.mathworks.com/…/sub-modules-of-epwm-type-1-4.html
GPIO mapping for ePWM output can be set in the same window(the green mark in the below picture), I guess it’s due to different C2000 part (?)
I am new to both C2000 processor and Simulink, sorry for such a simple question, very appreciate for your help, thanks.Hi Sir,
