Are you working on an embedded systems project and using the Keil microcontroller IDE? If so, you may need to create obj files as part of the compilation process before flashing your code onto the target microcontroller. In this tutorial, I'll guide you through the steps to create an obj file in Keil.

Step 1: Open your Keil project

First, open your Keil project in the Keil IDE. If you don't have a project set up yet, you can create a new one by going to File > New Project, and then follow the wizard to set up your project with the necessary configurations for your microcontroller.

Step 2: Add your source files

Next, add your source files to the project. You can do this by right-clicking on the 'Targets' tab in the project window and selecting 'Add Existing Files to Group...'. Choose the source files you want to include in the project and click 'Add'.

Step 3: Build your project

Once your source files are added to the project, it's time to build the project. Click on the 'Build' button in the toolbar or go to Project > Build Target to compile your code. This will generate the obj files for each of your source files.

Step 4: Locate the obj files

After the build process is complete, you can locate the obj files in the 'Output' folder within your project directory. The obj files will have the same name as your source files but with a .obj extension.

Step 5: Verify the obj files

To verify that the obj files were generated successfully, you can check the 'Build Output' window for any compilation errors or warnings. If there are no errors, the obj files should be ready for linking and flashing onto the microcontroller.

That's it! You've successfully created obj files for your Keil project. These obj files are essential for the compilation and linking process before you can flash your code onto the target microcontroller.

In conclusion, creating obj files in Keil is a fundamental step in the software development process for embedded systems. By following the steps outlined in this tutorial, you can ensure that your code is successfully compiled and ready for deployment onto the microcontroller. Good luck with your embedded systems project!
