基于MSP430的输入输出模块设计与实现
Design and Implementation of Input and Output Module Based on MSP430
摘要
Abstract
Monitoring system has been widely used in marine engineering.The data acquisition and output control are the core functions of the monitoring system.A digital I/O module based on MSP430F149 is designed to meet the requirements of monitoring system.The module transfers the data through RS485,and controls three analog inputs,one analog output,eight digital inputs,eight digital outputs and one PWM output through serial commands.The whole developing process of the module is introduced,including hardware circuit diagram,software flow diagrams,prototype of module software program and computer program based on Visual C ++.Experiments show that the whole module is stable and easy to operate,and can be well applied to various monitoring system designs.关键词
