MSP-EXP430FR5739 User Experience Demo

2.3

View, Edit, or Recompile the User Experience Code Using an IDE

There are different development software tools available for the MSP-EXP430FR5739 board. IAR
Embedded Workbench

™

KickStart

™

and Code Composer Studio

™

(CCS) IDEs are both available in a

free limited version. IAR Embedded Workbench allows 4KB of C-code compilation. CCS is limited to a
code size of 16KB. The software is available at

www.ti.com/msp430

To view, modify, or edit the User Experience code provided with the MSP-EXP430FR5739, an IDE
installation is required. The associated software package (see

Section 2.1

) supports both IAR and CCS

projects.

The User Experience source files and project folders are provided in the folder [Install
Path]\MSP-EXP430FR5739\MSP-EXP430FR5739 User Experience.

2.3.1

→

Connection to explicitly select the experimenter board.

2.3.2

Importing the CCS Project for the User Experience Code

To import the CCS project for the User Experience demo source code:

1. Create a workspace folder.

2. Open CCS and point to the newly created workspace folder.

3. Click Project

→

Import Existing CCS/CCE Eclipse Project.

4. Browse to the folder [Install Path]\MSP-EXP430FR5739\MSP-EXP430FR5739 User Experience that

was extracted from the associated zip file (see

Section 2.1

5. The project MSP-EXP430FR5739_UserExperience is automatically selected.

6. Click Finish to include the project in the current workspace.
