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!

Original Attachment has been moved to: Model.zip

Hi Eden Li,

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
