Install Code Composer Essentials

To edit and download code to the MSP430, Code Composer Essentials v3.1 or higher must be installed.

1. Download Code Composer Essentials Core Edition from

www.ti.com/cce

or from the included CD.

2. Extract the zip file and run the installation program.
3. Respond to the prompts to install the IDE.

NOTE:

IDE Selection

The eZ430-RF2500-SEH firmware is provided for both Code Composer Essentials and IAR
Embedded Workbench, and the user has the option to select the IDE of their choice.
However, the firmware is larger than IAR KickStart's 4KB limit, so a full license of IAR
Workbench is required to compile the application using IAR. An evaluation version of IAR is
available from

http://supp.iar.com/Download/SW/?item=EW430-EVAL

.

This document describes working with only Code Composer Essentials.

Install the eZ430-RF2500-SEH Sensor Monitor Firmware Source

To edit the original energy harvesting project, the source code must be installed. A specific folder structure
is required, and it is recommended to leave the default install path. If it is not possible to install to the
recommended path, please note that additional steps are required to open the project for the first time.

1. Download the eZ430-RF2500-SEH Demo and Source Code (

SLAC219

) from the

eZ430-RF2500-SEH

Development Tool web page

or from the included CD.

2. Unzip the archive and run SEH-firmware-install-vx.x.exe.
3. Respond to the prompts to install the application.
4. Follow the steps described in

Section 4.1.1

to download the firmware to the MSP430.
