STM32 Learning Notes: Building a FWlib 3.0 Project in IAR

Development environment: IAR5.3

Step 1: Download the function library

Download the STM32 V3.0 firmware function library from the ST official website (http://www.st.com/stonline/products/support/micro/files/um0427.zip).

Step 2: Copy the library file

After decompressing the downloaded software and hardware function library, copy the [Libraries] directory in the directory to your project directory, and then copy the four files main.c, stm32f10x_conf.h, stm32f10x_it.c, and stm32f10x_it.h in the [Template] directory under the [Project] directory to your directory, and then copy the four loading image files in the [Project]-[Template]-[EWARMv5] directory to your directory. So after these are completed, the files in your project are almost as shown in the figure below: Step 3: Load the file

Start the IAR5.3 development environment, choose to create a new project in the current workspace, and you will be prompted to select the tool, just select ARM; for the project template selection, just select the empty project. After the selection is completed, click the OK button, and you will be prompted to save the project file location, just save it directly to the previously created project directory. Then add each file group as shown in the figure below, and add the corresponding files. Step 4: Configure IAR 5.3 Right-click the project file (such as MyProject - Debug in the figure above), select the [Options] button in the right-click menu, and the project configuration tab will appear. Select [General Options], select [Device] in the [Target] page, and then click the device selection button to the right of [Device] to select your STM32 chip. After the selection is completed, it will be as shown in the following figure: Select [C/C++ Compiler], then select the [Preprocessor] page. In the [Additional include directories] text box, enter the header file address required to index your project. After the configuration is completed, it will be as shown in the following figure: Select [Linker], then select the [Config] page, select the [Override Default] check box, click the file selection button on the right side of the text box, and select the file you want to connect and configure in your project root directory (for example, if you plan to run the program in Flash, select stm32f10x_flash.icf). After the configuration is completed, it will be as shown in the following figure: Select [Debugger], then select the [Setup] page, and select [J-Link/J-Trace] in the [Driver] drop-down selection box. After the configuration is completed, it will be as shown in the following figure: After completing the subsequent operations, click the Make command button, and you will be prompted to save the Workspace file. Enter the name you want to save (for example, the above project is named MyProject). After clicking Save, the system will compile. After compiling, a warning Warning[Pe223]: function "assert_param" declared implicitly will be prompted. This is because the stm32f10x_conf.h file is not declared. Just declare it in the main.c header file. After the above four steps, you can use IAR to build a project of your choice. However, in the IAR configuration introduction, I only made a basic configuration introduction. If readers want to know more about the IAR environment usage instructions, they can directly refer to the IAR help file for in-depth study. If there are any unclear points in the article, I hope you will let me know. Thank you very much!!
