3. Software Setup
The included CD-ROM contains the Silicon Laboratories Integrated Development Environment (IDE), Keil software
8051 tools and additional documentation. Insert the CD-ROM into your PC’s CD-ROM drive. An installer will
automatically launch, allowing you to install the IDE software or read documentation by clicking buttons on the
Installation Panel. If the installer does not automatically start when you insert the CD-ROM, run
autorun.exe
found
in the root directory of the CD-ROM. Refer to the
readme.txt
file on the CD-ROM for the latest information
regarding known IDE problems and restrictions.
4. Silicon Laboratories Integrated Development Environment
The Silicon Laboratories IDE integrates a source-code editor, source-level debugger and in-system Flash
programmer. The use of third-party compilers and assemblers is also supported. This development kit includes the
Keil Software A51 macro assembler, BL51 linker and evaluation version C51 ‘C’ compiler. These tools can be used
from within the Silicon Laboratories IDE.
4.1. System Requirements
The Silicon Laboratories IDE requirements:
• Pentium-class host PC running Microsoft Windows 95 or later, or Microsoft Windows NT or later.
• One available COM port.
• 64 MB RAM and 40 MB free HD space recommended.
4.2. Assembler and Linker
A full-version Keil A51 macro assembler and BL51 banking linker are included with the development kit and are
installed during IDE installation. The complete assembler and linker reference manual can be found on-line under
the
Help
menu in the IDE or in the “SiLabs\MCU\hlp” directory (A51.pdf).
4.3. Evaluation C51 ‘C’ Compiler
An evaluation version of the Keil C51 ‘C’ compiler is included with the development kit and is installed during IDE
installation. The evaluation version of the C51 compiler is the same as the full professional version except code
size is limited to 4 kB and the floating point library is not included. The C51 compiler reference manual can be
found under the
Help
menu in the IDE or in the “SiLabs\MCU\hlp” directory (C51.pdf).
4.4. Using the Keil Software 8051 Tools with the Silicon Laboratories IDE
To perform source-level debugging with the IDE, you must configure the Keil 8051 tools to generate an absolute
object file in the OMF-51 format with object extensions and debug records enabled. You may 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 Applications Note
AN104 - Integrating
Keil 8051 Tools Into the Silicon Labs IDE
in the “SiLabs\MCU\Documentation\Appnotes” 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 the program 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.)

4.4.1. 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 rec-
ognized 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.
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.
4.4.2. 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 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. C8051F2xx family devices use the JTAG debug interface. You must select
JTAG
in the
Options->Debug
Interface
menu to enable connection to C80512xx target devices. Click the
Connect
button in the toolbar or
select
Debug->Connect
from the menu to connect to the device.
3. 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 con-
nect/download after build
in the
Project->Target Build Configuration
dialog. If errors occur during the
build process, the IDE will not attempt the download.
4. 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.

5. Example Source Code
Example source code and register definition files are provided in the “SiLabs\MCU\Examples\C8051F2xx”
directory during IDE installation. These files may be used as a template for code development. Example
applications include a blinking LED example which configures the green LED on the target board to blink at a fixed
rate.
5.1. Register Definition Files
Register definition files
C8051F200.inc and C8051F200.h
define all SFR registers and bit-addressable
control/status bits. They are installed into the “SiLabs\MCU\Examples\C8051F2xx” directory during IDE
installation. The register and bit names are identical to those used in the C8051F2xx data sheet. Both register
definition files are also installed in the default search path used by the Keil Software 8051 tools. Therefore, when
using the Keil 8051 tools included with the development kit (A51, C51), it is not necessary to copy a register
definition file to each project’s file directory.
5.2. Blinking LED Example
The example source files
blink.asm
and
blinky.c
show examples of several basic C8051F2xx functions. These
include; disabling the watchdog timer (WDT), configuring the Port I/O crossbar, configuring a timer for an interrupt
routine, initializing the system clock, and configuring a GPIO port. When compiled/assembled and linked this
program flashes the green LED on the target board about five times a second using the interrupt handler with a
timer.

6. Target Board
The C8051F2xx Development Kit includes a target board with a C8051F206/26 device pre-installed for evaluation
and preliminary software development. Numerous input/output (I/O) connections are provided to facilitate
prototyping using the target board. Refer to Figure 2 for the locations of the various I/O connectors.
