Apply C code for real-time Speedgoat operation

I am trying to simulate a MCU which is programmed via C. I have tried C Caller and it does return the function's result to Scope.

I also sent a constant to Speedgoat's analog output - it outputed the required voltage.

But I cannot merge these two - when I connect C Caller output to Analog Output, I get 'code generation information file does not exist'

Is it even possible to do so? My goal is to use the original controller C code in Matlab, to simulate it. That means I would need a main() loop, which calls other functions and these functions do something (like sending and receiving CANbus messages or reading analog input).

Whole simulation consists only of three elements - C Caller, Speedgoat setup and Speedgoat analog output.

Hi Mantas,

The integration of external C/C++ code in Simulink Real-Time is documented here. Please note that your original code might need to be adjusted in order to work with Simulink Real-Time/Speedgoat.

I hope this is helpful!

Best,

Dimitri

Thanks, I'll check it out.

Well it did not give me any usable information. I tried different blocks S-function (wrapper) - still same error.
