1. Introduction

This application note describes how to integrate the IAR

8051 Tools into the Silicon Laboratories IDE (Integrated

Development Environment). Integration provides an

efficient development environment with compose, edit,

build, download and debug operations integrated in the

same program.

2. Key Points

3. Create a Project in the Silicon

A project is necessary in order to link assembly files

created by the compiler and build an absolute “OMF-51”

output file. Follow these steps to create a project:

1. Under the “Project” menu, select “Add Files to

2. To add files to the build process, right-click on the file

The Intel OMF-51 absolute object file generated by

the IAR 8051 tools enables source-level debug from

the Silicon Laboratories IDE.

Once IAR Tools are integrated into the IDE, they are

called by simply pressing the “Assemble/Compile

Current File” button or the “Build/Make Project”

button.

See the included software, AN236SW, for an

example using the IAR tools.

Information in this application note applies to

Version 2.90 and later of the Silicon Labs IDE and

Version 4.05 and later of the IAR 8051 Tools.

First, select “IAR” from the “Select Tool Vendor” drop-

down list. Next, define the IAR assembler, compiler, and

linker as shown in the following sections.

The IDE will first look in the registry for the installed path
