摘要
分析了Stelliars系列内置以太网控制器的嵌入式芯片的特点和开发方式,提出了基于LM3S8962的以太网温度采集系统设计方案。通过在LM3S8962上移植uIPTCP/IP协议,实现了以太网通信功能。文中详细分析了LM3S8962对DS18B20进行温度采集时序控制过程并提出解决方法。PC机通过HTTP协议访问LM3S8962服务器,在网页浏览器上实时显示采集的温度值。
Through the analysis of chip feature and development mode of stelliars chip which embedded with Ethernet controller,this paper introduced a Ethernet temperature acquision design proposal based on LM3S8962.It adopted the uIP TCP/IP protocol stack,achieved the Ethernet communication。 The paper analyzed the read time slots with DS18B20 and advanced the solution.PC can access webserver in LM3S8962 through HTTP protocol and real-time display the temperature on web browser.
