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\Appnotes
directory on the CDROM 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.
Note:
If a project contains a large number of files, the "Group" feature of the IDE can be used to organize them. Right-click on
"New Project" in the Project Window. Select “Add Groups to Project”. Add predefined 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.
5.1.1. Building and Downloading the Program for Debugging
1. Once all source files have been added to the target build, build the project by clicking on the “Build/Make
Project” button in the toolbar or by selecting “Project
Build/Make Project” from the menu.
Note:
After the project has been built the first time, the Build/Make Project command will only build the files that have been
changed since the previous build. To rebuild all files and project dependencies, click on the “Rebuild All” button in the
toolbar or select “Project
Rebuild All” from the menu.
2. Before connecting to the target device, several connection options may need to be set. Open the Connection
Options window by selecting “Options
Connection Options...” in the IDE menu. First, select the "USB Debug
Adapter" option. The USB Debug circuitry is integrated onto the C8051T630 Motherboard.
3. Next, the correct debug interface must be selected. C8051T63x family devices and the F336 all use the Silicon
Labs "C2" 2-wire debug interface. Once all the selections are made, click the OK button to close the window.
4. Click the “Connect
”
button in the toolbar, or select “Debug
Connect” from the menu to connect to the device.
5. Download the project to the target by clicking the “Download Code” button in the toolbar.
Note:
To enable automatic downloading if the program build is successful, select “Enable Automatic Connect/Download after
Build” in the “Project
Target Build Configuration” dialog. If errors occur during the build process, the IDE will not attempt
the download.
6. Save the project when finished with the debug session to preserve the current target build configuration, editor
settings, and the location of all open debug views. To save the project, select “Project
Save Project As...” from
the menu. Create a new name for the project, and click on “Save”.
