2. Hardware Setup using a USB Debug Adapter
The target board is connected to a PC running the Silicon Laboratories IDE via the USB Debug Adapter as shown
in Figure 1.
1. Connect the USB Debug Adapter to the JTAG connector on the target board with the 10-pin ribbon cable.
2. Connect one end of the USB cable to the USB connector on the USB Debug Adapter.
3. Connect the other end of the USB cable to a USB Port on the PC.
4. Connect the ac/dc power adapter to power jack P1 on the target board.
Notes:
• Use the Reset button in the IDE to reset the target when connected using a USB Debug Adapter.
• Remove power from the target board and the USB Debug Adapter before connecting or disconnecting the
ribbon cable from the target board. Conn ecting or disconnecting the cable whe n the devices have power can
damage the device and/or the USB Debug Adapter.

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 develop ment 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 98SE or later.
• One available COM or USB 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 refere nce manual can be fo und 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.
Keil 8051 Tools Into the Silicon Labs IDE
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 projec t 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.)

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
build, right-click on the file name and select
appropriate (based on file extension) and linked into the build of the absolute object file.
Note:
Right-click on “New Project” in the
groups or add customized groups. Right-click on the group name and choose
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
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

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.
