摘　　要：该文介绍了MSP430单片机性能特点,结合MC14433A/D转换器的外部特性,给出MC14433与MSP430F449的接口电路及程序设计方法,实现模拟信号转换为计算机要求的数字信号。该电路接口简单,能较好地控制模拟信号的采集和转换。This thesis describes the performance of the MSP430 MCU. Combining with external characteristics of the MC14433M D, it presents the ways of design for the interface circuit and program between the MSP430F449 and MC14433 so as to realize the conversion of the analog signal into the digital signal requested by computer. The interface circuit is so simple to well control the acquisition and conversion of the analog signal.
