基于CPLD的温度采集系统的设计

本文介绍了一种基于CPLD的温度采集系统的设计方法，设计分为温度采集和LED显
示两个功能模块。与常用温度采集系统相比，本设计采用高精度数字温度传感器MAX6627与CPLD控制芯片EPM3128ATC144，系统具有较高的准确性、通用性和灵活性，功能扩展后可通过高速数据传输接口实现与PC机的通信，对采集数据进行综合分析与处理。

Abstract:This paper discusses a method of designing sample temperature data system by complex programmable logic device.The core of the whole system have been divided into two parts:temperature collection, LED display. The temperature collection controller based on complex programmable logic device, this system is based on MAX6627 precise digital temperature sensors report the temperature of a remote sensor and EPM3128ATC144.It
is more accurate mobility and in common use than others.It can communicate with PC when use high speed data transmission interface,then analyze and deal with these dates.
