提出了一种以LPC ARM2210处理器与嵌入式Linux操作系统为平台的温度采集系统。首先通过数字温度传感器LM75将温度数据采集并存储到嵌入式单片机的数据寄存器中,再把采集到的温度信息通过串口传送到LCD的显示电路上显示。通过设计硬件电路系统和软件系统,实现了温度采集以及显示的过程。由于嵌入式Linux具有实时性、方便性、实用性等多种强大的功能特性,本设计系统具有较强的实际应用价值。
A temperature acquisition system based on LPC ARM2210 processor and embedded Linux operating system is proposed. First of all, through the digital temperature sensor LM75 temperature data acquisition and stored in the embedded microcontroller data register, and then collected temperature information sent through the serial port to the LCD display circuit. By designing the hardware circuit system and software system, the process of temperature acquisition and display is realized. Because of the real-time embedded Linux, convenience, practicality and other powerful features, the design of the system has a strong practical value.
