基于FPGA的数显测温系统的设计

A Temperature Measurement System With Digital Display Based on FPGA

本数显测温系统采用Altera公司可编程FPGA芯片实现对单线式温度传感器DS18B20进行读写控制并输出至LDE数码显示,内部主要由DS18B20读写模块(由Mealy状态机控制),数据格式转换模块,显示译码模块组成,重点阐述了读写时序控制模块和数据格式转换模块的实现方式。

This paper presents a temperature measurement system with digital display. The FPGA chip of the Altera company is used to achieve the read and write control of the temperature sensor DS 18B20. The timing control module and the data format conversion module of the DS 18B20 are discussed in detail.
