摘要
针对单片机测温速度慢的不足，设计了采用DSl8820和TMs320vc5509A实现的温度测量显示系统。给出了系统的硬件连接图和软件实现流程，并且非常详细分析了如何用C语言实现比较精确的软件延时程序，从而满足单线总线协议的严格通信时序要求。
A Temperature Measurement and Display System Based on DS18B20 and TMS320VC5509A is designed, aim at resolving tJ~e slow speed of Measuring Temperature by MCUo The hardware design and software implementation method are given, how to achieve accurate software delay by c language is analyzed detailedly, in order to satisfy the strict time sequence requirement of the 1-wire bus.
