摘要
采用基于μC/OS-II实时操作系统和NicheStackTCP/IPStack网络协议栈的嵌入式以太网接口的设计方法,构建了满足系统数据实时传输和可靠传输的以太网结构。依据嵌入式系统软、硬件紧密结合的特点,选取采用FPGA芯片和以太网控制器DM9000A作为硬件平台,通过驱动程序设计和协议栈的移植,实现TCP和UDP等网络数据传输功能且可进一步实现HTTP协议和CGI服务。实验结果表明,该设计方案提供了一种接入Internet的低成本嵌入式系统和网络数据传输的有效方法,可用于远程监视控制、网络传输等领域。
The method based on μC/OS-II and NicheStack TCP/IP Stack is presented to design embedded Ethemet interface and build the structure of Ethemet transmission. According to the characteristics of embedded system software,select the FPGA chip and Ethernet controller DMg000A as the hardware platform,the driver stack design and transplant protocol,the implementation of TCP and UDP network data transmission function and the further implementation of HTTP protocol and CGI services. The experimental results show that,this scheme provides an effective method for low cost embedded systems and network data transmission of an ac- cess of Intemet, can be used for remote monitoring and control, network transmission and so on.
