STM32F29I + MATLAB

Hi,

I am trying to program the discovery board using MATLAB+Simulink. Unfortunately the examples are not working on my board.

I followed the simple example on Mathworks. I changed the pin to PG13, because on my board the LED is connected to this port.

http://de.mathworks.com/help/supportpkg/stmicroelectronicsstm32f4discovery/examples/getting-started-with-embedded-coder-support-package-for-stmicroelectronics-stm32f4-discovery-board.html

Everything compiles without an error. The program is downloaded to the board, but nothing happens.

This is my board:

Can anyone help me to get it working?

Best Regards,

Kai

I also followed this video, but it is not working:

Simulink does not recognize the ''compiler'', which should be STM32CubeMX. The problem is also discussed at mathworks.

stm32#comment_295551

The difference between the setup in the video and my setup is the MATLAB version. Is STM32-MAT/TARGET compatible with MATLAB R.2015a?

Hello smrtkai,

Can you debug your application? Is it stopping execution at some level?

We need t understand how exactly it is not working.

Thanks for the quick response. Sorry, I forgot to post the error message. Matlab/Simulink is unable to start STM32CubeMX, when I try to build the model. The only difference between the setup in the video and my setup is the Matlab version. I have Matlab R2015a installed.

Matlab returns the following error:

An installed compiler was not detected. Certain simulation modes, as well as host-based coder builds require that a compiler be installed. Please install one of the supported compilers for this release as listed at:

http://www.mathworks.com/support/compilers/R2015a/win64.html

MATLAB must be restarted after the compiler is installed.

Component: Simulink | Category: Model error

I followed another approach, but that is not related to your STM32-MAT/TARGET. Its with the hardware support package downloadable directly within Matlab. With this approach the compiler works fine but nothing is executed on the device itself.

I figured out, that the error occurs in ''setup_for_lcc''. LCC stands Local C Compiler. But

there is no LCC shipped with Matlab 64bit. Changing line 67 in setup_for_lcc.m to ''args.mexOpts = rtwprivate('getMexCompilerInfo');'' fixed the problem.

The question is: Why is ''setup_for_lcc'' invoked, when there are alternate and more advanced compilers installed and setup?

And if you follow the instructions provided in the error message, what do you get?

I followed the instructions by installing ''Windows SDK 7.1'' and ''Visual Studio 2013 Professional''. As you can see in my previous post, the compilers are configured correctly. I configured the compilers using ''mex -setup''.

Hello,

this pb will be resolved for next STM32-MAT/Target version.

Please, edit \STM32\rtw\stm32.tmf

Line 68

Please add ''COMPILER_TOOL_CHAIN = default''

in order to have:

SYS_TARGET_FILE = stm32.tlc

COMPILER_TOOL_CHAIN = default

MAKEFILE_FILESEP = /

Save file.

It should be ok.

Best regards

Pascal

Finally, I have gotten the Matlab licenses to program STM32 microcontrollers with Matlab.

I want to report another issue with the Matlab target. If you create the STM32CubeMX project from within Matlab, you cannot generate the code. You have to create the STM32CubeMX -project on its own and select it within Matlab. And you need to generate the code at least once from STM32CubeMX. If not Matlab will generate an output file (*.out) with the content ''Dumy File'' [no typo ;-)].

I would really appreciate an official guide on how to use the Matlab target. Maybe there exists one, that I haven't found yet.

I have encountered another problem. When using MATLAB R2015a it is possible to generate code through STM32CubeMX but there is no Matlab-generated code within the Keil-project.

When I click on ''Build Model'' in MATLAB, STM32CubeMX asks for a project name and location. After setting the configuration the code is generated, but it is simply the code generated from STM32CubeMX. Matlab-Code is completely missing. Although I did set the configuration in advance, Matlab asks for the project configuration. :(

Is anyone using Matlab to generate code for STM32 at all? Seems like there are a lot of issues to be solved, to get it working properly.

Thanks for your help in advance.

Anyone, who is interested in the official ST guide on ''Usage of STM32-MAT target'', there exist an Readme file.

It is hidden at file:///C:/MATLAB/STM32-MAT/STM32/Readme.html
