摘要
以低功耗单片机MSP430F247为控制核心,通过对GPS模块、大气压传感器、湿度传感器(SHT71)与时钟芯片(DS1302)采集的信息进行处理,文中设计了一个能测量和显示经度、纬度和海拔高度、大气压力、温度、湿度、速度和移动方向的系统.该系统具有电子指南针、电子导航、路点轨迹描绘、天气预测、秒表、万年历、时钟、闹钟、音乐播放和自动校正时间的功能.
Taking the low consumption single chip microprocessor MSP430F247 as the core of control,through sampling the outputs of Global Position System(GPS) module,atmospheric pressure sensor,humidity sensor(SHT71) and the clock chip(DS1302),the system which can measure and display the longitude,latitude,altitude,atmospheric pressure,temperature,humidity,speed and direction of movement is designed in this paper.This system has the functions of electronic compass,electronic navigation,waypoint trajectory description,weather forecast,stopwatch,calendar,clock,alarm clock,music player and automatic correction time.
