1、摘要摘要本文旨在设计一个基于MSP430单片机的高精度的温度测试系统，以应用于实际温度测控。有两个主要要求：1.用LCD做显示器。2.微功耗实现。预期成果是使得该系统测温精度达到±0.5℃，测温范围达到0℃-100℃，实现uA级功耗。基于上述要求，论文首先介绍了超低功耗16位单片机MSP430F149和数字温度传感器DS18B20的基本特性，内部结构和应用，然后结合液晶显示模块MG-12232，画出了PROTEL电路图，PCB图，设计了一个小型测温系统，并写出了相应的程序代码。利用MSP430单片机的超低功耗以及DS18B20的单线接口方式
2、，实现了整个系统的低功耗，结构简单，性能稳定，经济实用。最后基于集成开发环境IARWorkbench给出了主要的C430函数。关键词：测温系统，MSP430F149，DS18B20otherstaffoftheCentre.Duringthewar,ZhuwastransferredbacktoJiangxi,andDirectorofthenewOfficeinJingdezhen,JiangxiCommitteeSecretary.Startingin1939servedasrecorderoftheWestNorthOrganizat
