About Code generation in the Model Based Software

[edenli]

Hi Guys,

I used the simulink/stateflow call external *.c and *.h files,and generated the Test_1_initialize(void) as below,

but,i wanna put the int_xx() function of the ad.c file in Test_1_initialize(void),shown as yellow mark.

I put stateflow in the Initialize Function,simulink shows that it is not supported,so i don't know how to do!

The attachment is the model built by myself.

Who can help me?Thanks very much!

Hi Eden Li, 

The Simulink error you are getting is normal and is listed as a Mathworks limitation: Initialize, Reset, and Terminate Function Limitations - MATLAB & Simulink - MathWorks Deutschland 

Charts are not supported by the block you want to use in your model.

Nonetheless, we may offer you and alternative:

Just recently another member of the community had a similar request: please see this topic:MCToolbox can't find my hand written code. Does it support S-Function? 

We've also created a tip for it: MBD Toolbox - Tip of the Day‌ Tip #3: MBD Toolbox - Add custom code to your Simulink model

Let us know if you managed to implement your functionality this way.

Hope it helps!

Daniel

Hi daniel,

I haven't realize this function ,The link you had sent to seams not realize  my goal that mentaioned abve(the yellow mark) .

It is not a direct call of your function but functionally is the same outcome.

The Matlab S-function will call your custom function via a wrapper:

That in turns calls the user code:

All you have to do is:

#1: place the S-function in the Initialize Function Block

#2: customize the S-function Builder to reference the code you want to call

#3: follow the tip#3 to copy all custom files in the final generation code folder: https://community.nxp.com/thread/449904 

Attached is and example with Matlab/Simulink + copy file(that needs to customized for each PC)

Hope this helps!

Best regards,
Daniel
