Title The Data Acquisition System Based On MSP430F1612

Abstract Measurement and control instruments and systems play as a gatekeeper in industrial production and the role of the mentor, and the development of measurement and control system of automatic control is becoming more and more fast. MSP430 series which have the low voltage, low power consumption, strong processing ability, system working stability, wide range of both inside and outside, convenient and efficient development environment and other characteristics,is occupying the more and more important status in the development and application. This graduation design is based on MSP430F1612, designed a data acquisition system, mainly related to input A/D conversion, serial communication, and the output of D/A conversion program design. A/D and D/A all use built-in peripherals, including A/D conversion of input voltage, the result is outputed by D/A converting analog. Communication consists of sending and receiving,which has made the automatic transceiver design on hardware design, in order to avoid data loss.
