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

    Is an update for the MATLAB-Target on the development roadmap?

    ''STM32 Embedded Target has been developped for MATLAB® R2014a version''

    Hi,

    I wrote a step by step guide for myself on ''How to setup STM32-MAT/TARGET with MATLAB R2015a''.

    #

    # Software

    #

      - Windows 10

      - MATLAB R2015a

      - Keil uVision V5.16.0

      - STM32CubeMX V4.11.0

      - STM32-MAT/TARGET 4.2.0

      - git version 1.9.5.msysgit.1

    STM32 Embedded Target (STM32-MAT/TARGET) has been developped for MATLAB® R2014a

    version. There are some issues that have to be solved to get the STM32-MAT/TARGET

    working with MATLAB R2015a.

    0.  Install STM32-MAT/Target

        http://www.st.com/web/en/catalog/tools/FM147/CL1794/SC961/SS1533/PF258513

        file:///C:/MATLAB/STM32-MAT/STM32/Readme.html

        see also file:///C:/MATLAB/STM32-MAT/STM32/html

    1a. Local C Compiler Issue

        ''Changing line 67 in setup_for_lcc.m to the following line fixed the problem.''

           args.mexOpts = rtwprivate('getMexCompilerInfo');

        C:\Program Files\MATLAB\R2015a\toolbox\rtw\rtw\setup_for_lcc.m

        NOTE: You need to have administrative rights, when editing this file.

    1b. Compiler Tool Chain

        Official answer from ST to fix this issue.

        See https://my.st.com/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Flat.aspx?RootFolder=%2fpublic%2fSTe2ecommunities%2fmcu%2fLists%2fcortex%5fmx%5fstm32%2fSTM32F29I%20%2b%20MATLAB&FolderCTID=0x01200200770978C69A1141439FE559EB459D7580009C4E14902C3CDE46A77F0FFD06506F5B

        Edit C:\MATLAB\STM32-MAT\STM32\rtw\stm32.tmf

        In Line 68 add ''COMPILER_TOOL_CHAIN = default''

    2.  Create STM32CubeMX project

        The STM32CubeMX project (*.ioc) needs to be generated separately. It is not

        possible to create a new project from within MATLAB. Additionally the code

        neeeds to be generated once before using it with the STM32-MAT/TARGET.

        Just select ''Project > Generate Code''.

    3.  Configure Simulink Model

        There are two places where the preferences for the STM32-MAT/TARGET can be

        set.

        In Simulink:

        File > Simulink Preferences > Configuration Defaults > Code Generation

        Simulation > Model Configuration Parameters (Strg + E) > Code Generation

    4.  Create Simulink Model and Build Model

        Create a new Simulink Model, select ''STM32_Config'' from ''Target Support

        Package - STM32 Adapter/MCU_CONFIG'' and select the created STM32CubeMX

        from step 2. Clicking on ''Build Model'' will generate a Keil project, that

        can be ''build and run'' on the stm32 mircocontroller.
