  • 基于PIC24FJ64GA002的小型WEB服务器设计与应用

    本文以PIC24FJ64GA002 16位单片机为处理器控制10BASE-T SPI以太网控制器ENC28J60,实现了单片机的上网。应用Microchip TCPIP Stack协议,实现了HTTP,FTP协议和基于CGI动态网页的设计。操作员可以在远程计算机上以Web页面的方式实现系统的监控,也可以通过FTP更新系统参数和数据。最后将本系统应用在了生物发酵远程监控系统中,得到了良好的效果。

  • ZOPC_Server(ZLG通用OPC服务器)软件

    ZOPC_Server是一个OPC服务器软件,本软件通过插件方式操作底层硬件。其中三个标准插件(CAN,DeviceNet,iCAN)支持操作全部的ZLGCAN系列接口卡 和ZLGDeviceNet系列板卡以及iCan协议系列卡,只要在一台PC机上插上ZLGCAN系列接口卡或ZLGDeviceNet系列板卡中的任何一种或几种,再运行本服务器软件,在服务器软件中进行一些相关配置以后,就可以使用任何一种支持OPC协议的客户端软件(比如组态软件:组态王、MCGS和INTOUCH等等)来连接到此服务器,通过此服务器来跟CAN网络、iCAN网络或DeviceNet网络进行数据的传输。   ZOPC服务器现阶段带有五个扩展插件,分别为CANopen,DAQ,GPRS,Modbus,Modbus_RTU_ASCII。这些扩展插件可以按需要单独安装。CANopen插件可操作ZLG生产的CANopen主站卡。DAQ插件操作ZLG的DAQ系列数据采集卡,将数据采集卡采集的数据上传到ZOPC服务器中供客户端使用。GPRS插件可以将GPRS模块的数据上传到ZOPC服务器中。Modbus插件是通过以太网操作从站。Modbus_RTU-ASCII插件是通过串口操作从站。随后还会添加新的插件支持对新开发的产品的操作。

  • WP247 - Virtex-5系列高级封装

    The exacting technological demands created byincreasing bandwidth requirements have given riseto significant advances in FPGA technology thatenable engineers to successfully incorporate highspeedI/O interfaces in their designs. One aspect ofdesign that plays an increasingly important role isthat of the FPGA package. As the interfaces get fasterand wider, choosing the RIGHT package has becomeone of the key considerations for the systemdesigner.
