PAGE 南 京 工 程 学 院 毕业设计说明书(论文) 系 部： 康尼学院 专 业： 通信工程 题 目：基于MSP430的温度检测系统设计与实现 2013 年 6 月 南 京 MSP430-based temperature detection system design and implementation A Dissertation Submitted to Nanjing Institute of Technology For the Academic Degree of Bachelor of Science By Chao Wang Supervised by Technician Lichun Wang College Nanjing Institute of Technology June 2013 摘要 MSP430单片机是德州公司最新开发的具有16位总线带FLASH 的单片机，由于它的性价比和集成度高，受到广大技术开发人员的青睐。它的可靠性能比较好，加强电干扰运行不受影响，适应工业级的运行环境，在各种行业中都占有重要的位置，越来越多的领域应用到以单片机为控制核心，用液晶显示作为显示终端的数字化控制设备，通过单片机对被控对象进行智能控制。 MSP430单片机将会在工程技术应用中得到广泛的应用。而且，它是通向DSP系列的桥梁，随着自动控制的低功耗化和高速化，MSP430系列单片机将会得到越来越多人的喜爱。 通过这次毕业设计，我对MSP430单片机有了完整的了解，并且着重了解了MSP430F149芯片的原理图以及它的工作原理，对内部的硬件资源和自身的汇编语法进行了实验，把它和DS18B20温度传感器联系在一起实现了温度的测量以及报警。 关键词：MSP430；超低功耗；单片机；DS18B20 Abstract Texas MSP430 microcontroller is the latest development of a 16-bit bus with FLASH MCU, due to its cost-effective and highly integrated, by the majority of technology developers of all ages. Its reliability is better, enhancing electrical interference unaffected, adapt industrial-grade operating environment, in a variety of industry occupies an important position in both, applied to more and more areas to microcontroller core, with LCD as a digital control display terminal equipment, through the controlled object MCU intelligent control. MSP430 microcontroller applications engineering technology will be widely used. And, it is a bridge leading DSP family, with automatic control, low power consumption and high speed, MSP430 MCU will get more and more peoples favorite. Through this graduation project, I have a complete understanding of the MSP430 microcontroller, and focus on understanding the MSP430F149 chip schematic and it works, and the internal hardware resources and their own assembler syntax conducted experiments it and DS18B20 linked to the temperature sensor of the temperature-measuring and alarm.
