摘要
设计了一种以DSP为控制核心的温度监测和显示系统。该系统采用数字温度传感器DS18B20进行温度采集,以TM320240EFGW型液晶显示模块进行实时显示,以RS232通用串行接口与PC机进行通信。该系统具有电路结构简单、功耗低、实时性强、数据传输方便等优点。
A temperature monitoring and displaying system based on DSP is designed.A digital temperature sensor DS18B20 is used to collect temperature.And a kind of TM320240EFGW liquid crystal display module is used for real-time display.An Universal Serial RS232 interface is used to communicate with a PC.Therefore,this system has many advantages such as sample circuit,low power consumption,easy real-time data transmission,and so on.
