【摘要】：TMS320F2812作为一款性能优越的数字信号处理器,缺乏对以太网通信的支持使其无法满足电能质量监测领域日益增长的通信需求;针对电能质量监测的数据通信需求,设计了基于ENC28J60芯片的TMS320F2812以太网通信接口,在简要介绍ENC28J60和TMS320F2812芯片的基础上,重点阐述了以太网接口设计,包括以太网独立控制器ENC28J60的外围硬件电路设计,驱动程序设计及上层通信软件的设计;用TMS320F2812的SPI引脚接口与ENC28J60相连,通过微指令编程实现ENC28J60的控制逻辑,网络层、传输层采用嵌入式TCP/IP协议,应用层采用HTTP协议;通过在与接口相连的计算机上运行TCP/UDP Socket调试工具对通信进行测试;实验证明通信稳定可靠,实现了TMS320F2812的以太网通信。
[Abstract]:As a digital signal processor with superior performance, TMS320F2812 is unable to meet the increasing communication needs in the field of power quality monitoring because of its lack of support for Ethernet communication. The TMS320F2812 Ethernet communication interface based on ENC28J60 chip is designed. Based on the brief introduction of ENC28J60 and TMS320F2812 chip, the design of Ethernet interface is emphasized, including the peripheral hardware circuit design of ethernet independent controller ENC28J60. The driver is designed and the upper layer communication software is designed, the SPI pin interface of TMS320F2812 is connected with ENC28J60, the control logic of ENC28J60 is realized by microinstruction programming, the network layer and transmission layer adopt embedded TCP/IP protocol, and the application layer adopts HTTP protocol. The communication is tested by running the TCP/UDP Socket debugging tool on the computer connected to the interface, and the experiment proves that the communication is stable and reliable, and the Ethernet communication of TMS320F2812 is realized.
