基于AM335X平台的Ethercat实现.pdf
EtherCAT(以太网控制自动化技技)是一种用于确定性以太网的高性能技业通信协议,它扩展了IEEE 802.3 以太网标准,使得数据传输中具有可预测性定时及高精度同步等特点。这个开放性标准作为 IEC 61158 的组成部分,常用于机械设计及运动控制等应用中。EtherCAT 采用标准的IEEE802-3 以太网帧,帧结构如图 1。EtherCAT 协议直接用标准以太网的帧格嵌传输数据,并不修改其基本结构(ethercat communication)

serial to parallel
直接序列扩频通信中采用QPSK调制时,须将产生的串行数据首先串并变换成两路,本程序就是实现这种串并变换!(Direct sequence spread spectrum communications using QPSK modulation, it is necessary to have a string of serial data and converted into the first two, the process is to realize such a string, and transform!)

通过串口采集下位机信息 smart
本程序是基于LABWINDOWS/CVI 的,主要是通过串口采集下位机信息,然后显示状态信息并通过串口发送命令字节。(The program is based on LABWINDOWS/CVI.It get message from RS232and display status,then send command by RS232.)
