How to create an STM32F2xx project from scratch using MDK (graphic tutorial)

Step 1: Download the standard peripheral firmware library.

        Download link: http://www.st.com/stonline/stappl/resourceSelector/app?page=resourceSelector&doctype=FIRMWARE&ClassID=1734

        Download the STM32F2xx Standard Peripherals library. The latest version is V1.1.0, but it is recommended to download V1.0.0 because the latest version V1.1.0 on the official website lacks the cm3.c file.

        It is recommended to use Thunder to download, because if you download using a browser, the download will stop at 99%, but you can complete the download using Thunder.

        After downloading, unzip it, as shown below:

  |--stm32f2xx_stdperiph_lib_um.chw

Step 2: Organize the project directory

     Create a new directory anywhere on your computer, such as APP, and then create two new directories, Project and User, under the APP directory.

     Next, copy the Libaries directory under the standard peripheral firmware library that you downloaded and unzipped earlier to the APP directory.

    Then create two new directories, Obj and List, under the Project directory.

   Finally, select a template source file from the previously unzipped files and copy it to the User directory. Here, for example, .\STM32F2xx_StdPeriph_Lib_V1.0.0\Project\STM32F2xx_StdPeriph_Examples\GPIO

Copy the source code in the directory to the Usr directory.

    Once you have these prepared you can proceed to the next step.

   The following figure shows the directory of APP:

Step 3: Create MDK project

       Open MDK, click Project->New uVision Project..., then a dialog box pops up and asks you to select the project directory. Select APP/Project here and name the project Demo, as shown below:

                                                                    image 3

After clicking Save, a dialog box will pop up to select the MCU type. Here, select STM32F207VC from STMicroeletronics, as shown below:

                                                                        Figure 4

After clicking OK, a dialog box pops up, select whether to let MDK automatically generate the startup file startup_stm32f2xx.s to the project. Here, because there is already a startup file, select No here.

Step 4: Add project files

     First, rename the project to Demo, and then click the Manage Conponents... button on the toolbar, as shown in the red circle in the figure below:

                                                                                       Figure 5

Open the following interface:

                                               Figure 6

The next step is to add groups and source files to the project. First, add four groups: Lib, User, CMSIS, and StartUp.

Then add source files for each group:

Lib->Add all source files under APP\Libraries\STM32F2xx_StdPeriph_Driver\src. Of course, you can also select only some files as needed.

User->Add all source files in the APP\User directory, except system_stm32f2xx.c, because this file will be added in the next CMSIS group.

CMSIS->Add the core_cm3.c file in the APP\Libraries\CMSIS\CM3\CoreSupport directory

                Add the system_stm32f2xx.c file in the APP\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F2xx directory.

StartUp->Add the startup_stm32f2xx.s file in the APP\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F2xx\startup\arm directory.

This will add all the files.

Step 5: Add header files

Click the Target Options.. button on the toolbar, as shown in the red circle in the figure below:

                                                                   Figure 7

The following dialog box pops up, select the C/C++ tab, add the USE_STDPERIPH_DRIVER macro in the Define: column under Preprocess Symbols, and add the include path under Include Paths, as shown below:

Note: The macro USE_STDPERIPH_DRIVER can be found in the header file stm32f2xx.h. It means to open the standard peripheral firmware library. Of course, you can also modify stm32f2xx.h to open this macro, but it is not recommended.

                                                                            Figure 8

The paths included are all directories of header files, as shown below:

                                       Fig. 9

Then set the output directory and the listing directory.

Under the Output tab, click the Select Folder for Objects.. button, and then select the APP\Project\Obj directory as the output directory.

Under the Listing tab, click the Select Folder for Listings... button, and then select the APP\Project\List directory as the list directory.

At this point, all the project settings are basically set up, and the next step is to compile and burn.

Step 6: Compile the project

Click Compile and find an error. Comment out #include "stm32_eval.h" in the main.c file.

1. //#include "stm32_eval.h"  

Then you can compile it.
