Something Wrong with Simulink C code generation in CAN bus communication

While I was doing the MBD(Model Based Design) using SImulink,Keil,stm cubemx and stm32_mat_target. I build a simple model in the Simulink then it goes well when I just click the run button.

This is the simple model, CAN1 read the data and CAN2 send it.

But when I press Build Model and generate the C code for stm32, the compiler in Keil tell me that ‘cannot open source input file “can_message.h”：No such file or dictionary’

the compiler tell me the code which Simulink generated is wrong and the can_message.h is missing.

@Yuri ricardo I have the same problem. Have you been able to find a solution?

Hello someone was able to fix it?

You can copy the can_message.h in the path

C:\Program Files\MATLAB\R2018a\toolbox\shared\can\src\scanutil\can_message.h

under

C:\Program Files (x86)\MATLAB\STM32-MAT\STM32\addSrc\inc\ 

(adjust paths for yourself). Then, go to Configuration Parameters under Simulink, STM32 Project Files -> Select include files -> choose can_message.h

If compiling fails, you might need to edit can_messages.h so that

#include "tmwtypes.h"

becomes

#include "rtwtypes.h"
