摘要
为了实现以太网数据与RS422串行通信接口之间的转换,设计了采用TMS320F2812DSP和以太网控制器芯片AX88180实现的嵌入式系统,给出了系统的总体方案、硬件结构、数据交互方法以及软件实现方法。在网络通信速度为1 Gb/s、串行通信速度为230.4 kb/s的实验环境下进行测试,测试结果表明,该方案设计简单,运行稳定可靠,具有一定的使用价值。
In order to realize the data conversion between the Ethernet and RS422 UART, an embbedded system based on TMS320F2812 DSP and Ethernet controller chip AX88180 is designed. The design, hardware structure, data alternation method, software flow chart are presented. The system is tested by 1 Gb/s Ethernet and 230.4 kb/s environment, experiments results show that the method is feasible, the simple design and stable correct results make this method very ascendant in practical application.
