基于FPGA的数字温度传感器接口设计

数字温度传感器在实际应用中广受欢迎,以其为基础构成的温度测量系统,线路简单、硬件开销少、编程灵活、成本低廉。介绍了数字温度传感器常用的两种串行总线(单总线和系统管理总线)的接口标准和特点,分析了在现场可编程门阵列(FPGA)中设计这两种接口的方法,并描述了相应的硬件电路和软件设计方案。

Design of Digital Temperature Sensors Interface Based on FPGA

The digital temperature sensors are very popular in practical application,taking it as foundation to constitute the temperature measurement system,the circuit is simple,the hardware expend is few,the programming is flexible,the cost is inexpensive.The interface standards and the characteristics of two serial buses commonly used in digital temperature sensors(1 wire bus and system management bus) are introduced,the methods of design these two kinds of interfaces in the Field Programmable Gate Arrays(FPGA) are analyzed,the corresponding hardware circuits and software design plans are also described.
