1.1 The msp430f16x deluxe development board

Overview

This module describes a full-featured development board for the Texas Instruments MSP430F16x series of mixed-signal microprocessors. This hardware system was designed to allow students or engineers to fully excercise and explore the capabilities of the MSP430 microcontroler.

This module is meant to serve as a general technical overview and instruction manual for the development board. The two pictures below show a general block diagram of the development system and a picture of the board that highlights some of the major peripherals.

System features overview

The MSP430F16x deluxe development board was designed to offer acces to a broad range of the peripheral devices available on the MSP430, thus allowing the testing and evaluation of the full capabilities of the MSP430 line of processors.
