5. Using the Keil Software 8051 Tools with the Silicon Laboratories IDE
To perform source-level debugging with the IDE, configure the Keil 8051 tools to generate an absolute object file in
the OMF-51 format with object extensions and debug records enabled. Build the OMF-51 absolute object file by
calling the Keil 8051 tools at the command line (e.g., batch file or make file) or by using the project manager built
into the IDE. The default configuration when using the Silicon Laboratories IDE project manager enables object
extension and debug record generation. Refer to "AN104: Integrating Keil 8051 Tools into the Silicon Labs IDE" in
the “
SiLabs\MCU\Documentation\ApplicationNotes
” directory on the CD-ROM for additional information on using the
Keil 8051 tools with the Silicon Laboratories IDE.
To build an absolute object file using the Silicon Laboratories IDE project manager, you must first create a project.
A project consists of a set of files, IDE configuration, debug views, and a target build configuration (list of files and
tool configurations used as input to the assembler, compiler, and linker when building an output object file).
The following sections illustrate the steps necessary to manually create a project with one or more source files,
build a program, and download it to the target in preparation for debugging. (The IDE will automatically create a
single-file project using the currently open and active source file if you select Build/Make Project before a project is
defined.)
5.1. Creating a New Project
1. Select Project
New Project to open a new project and reset all configuration settings to default.
2. Select File
New File to open an editor window. Create your source file(s) and save the file(s) with a
recognized extension, such as .c, .h, or .asm, to enable color syntax highlighting.
3. Right-click on “New Project” in the Project Window. Select Add files to project. Select files in the file browser
and click Open. Continue adding files until all project files have been added.
4. For each of the files in the Project Window that you want assembled, compiled and linked into the target build,
right-click on the file name and select Add file to build. Each file will be assembled or compiled as appropriate
(based on file extension) and linked into the build of the absolute object file.
5. If a project contains a large number of files, the “Group” feature of the IDE can be used to organize. Right-click
on “New Project” in the Project Window. Select Add Groups to project. Add pre-defined groups or add
customized groups. Right-click on the group name and choose Add file to group. Select files to be added.
Continue adding files until all project files have been added.
