Are you working on embedded systems programming using Keil? Creating obj files can be a crucial step in the process. Obj files are intermediate files that contain the compiled code and are used to generate the final executable file. Here's a step-by-step guide on how to create an obj file in Keil:

1. Open Keil: Launch the Keil IDE and open your project that contains the source code you want to compile.

2. Configure Build Options: Go to the Project menu and select 'Options for Target...'. In the Target tab, configure the necessary settings such as selecting the microcontroller, memory model, and output file format.

3. Build the Project: Once the build options are configured, click on the 'Build' menu and select 'Build Target' to compile the source code. Keil will generate the obj file as part of the compilation process.

4. Locate the Obj File: After the build process is complete, navigate to the output folder of your project to find the generated obj file. The obj file will have a '.obj' extension and is ready to be used for further steps in the programming process.

By following these steps, you can easily create an obj file in Keil and streamline your embedded systems programming process. Whether you're working on a simple project or a complex embedded system, understanding how to create obj files is an essential skill for efficient development. Happy coding!
