Overview

This design utilizes existing Launchpad evaluation kits and BoosterPack plug-in modules to demonstrate the implementation of a SMBus-based system using Texas Instrument’s MSP430 SMBus Library.

Features

• Low-power
• Cost-effective
• Shows implementation of smbuslib as Master and Slave
• Uses TMP006 to measure temperature of objects remotely
• Simple LED dimmer implementation using MSP430 as SMBus slave
• Easy-to-use GUI
