  • 基于CAN总线的综自通讯规约设计

    介绍一种基于CAN总线的牵引变电站自动化系统通讯规约的设计,CAN通讯规约采用标准帧,报文采用主动发送和发送查询两种处理形式。该设计在城市轻轨与地铁牵引变电站中的应用表明:可实现间隔层和通讯处理层的数据快速、可靠的交换,提高牵引变电站的安全性和稳定性 。 Abstract:  This paper firstly presents a kind of design dealing with communicational protocol to the traction substation automation system based on CAN bus,and then comes up with the ideas that all Frames of CAN communicational protocol should adopt the standard frame,and that messages be processed by two ways:sending initiatively and sending quiries.Subway and light rail application shows that the use of the CAN bus is possible to exchange data quickly and reliably between the layers of the middle and the communicational processing,hence to improve the safety and stability of traction substations.

  • LPC1700以太网MIIM接口应用笔记

    The LPC1700 Ethernet block contains a full featured 10 Mbps or 100 Mbps Ethernet MAC (Media Access Controller) designed to provide optimized performance through the use of DMA hardware acceleration. Features include a generous suite of control registers, half or full duplex operation, flow control, control Frames, hardware acceleration for transmit retry, receive packet filtering and wake-up on LAN activity. Automatic frame transmission and reception with Scatter-Gather DMA off-loads many operations from the CPU.

    PhpDig is a search engine written in PHP that uses a MySQL database backend. It features indexing of both static and dynamic pages, spidering of almost all links in HTML content, in hrefs, areamaps, and Frames, and full text indexing. The search results appearence is skin-able, using a very simple templates system. PhpDig是一个用PHP编写的搜索引擎,它使用MySQL数据库后台。它的功能有静态和动态页面索引,在HTML内容中用hrefs, areamaps,和Frames以及全文本索引构成所有的链接网。搜索结果的外观是可定制外观的,使用一个非常简单的模板系统。

    曾有许多网友问我有关JavaScript与框架(为求方便,以下均用frame表示)合用的问题。事实上,若您同时想用Frames和JavaScript的功能,首先您必需拥有Netscape Navigator 2.0 (或以上)浏览器( 至少目前是如此)。当然也有某些浏览器支援Frames的功能--如:Oracle开发的PowerBrowser,但此浏览器还只是Beta版,目前尚不支援JavaScript。

    Its a text-fading linking ticker type applet that will fade text of any color over any color background. It features rollover color feedback, and will pause when rolled over so the user doesn t have to "chase" links. It uses very little processor power and source is included! Now supports Frames!

  • UCOS/II for ICCAVR - The version of UCOS/II is 2.04 - the original port was done by Ole Saether

    UCOS/II for ICCAVR - The version of UCOS/II is 2.04 - the original port was done by Ole Saether for the IAR compiler. Jens E. Holtegaard ported one version using ICCAVR. Joerg Meyer did another port (using Jens port as a start?). This is basically Joerg s port plus a little bit of changes and documentation by me. - YOU MUST DOWNLOAD THE MAIN PART OF THE UCOS/II FROM THE UCOS/II WEBSITE http://www.ucos-ii.com . The supplied project file assumes the portable source is in the ..\source directory. - Joerg has written couple document showing the stack Frames etc. but it is in German :-) They are included in this directory. - The Timer2 overflow interrupt is used for Timer Tick. If you want to change that, modify os_cpu_c.c and os_cpu_a.s - I have tested this using ATMega103 with and without external RAM using AVR Studio simulator. See test1.c test program. Both Code Compressed (PRO) and STD versions have been tested.

  • This example streams input from a ADC source to a DAC. An analog signal is acquired block-by-block

    This example streams input from a ADC source to a DAC. An analog signal is acquired block-by-block into SDRAM from the ADC (an AD9244 in this example). The Frames are then output with a one-frame delay to the DAC (an AD9744 in this example). In this example, no processing is done on the Frames. They are passed unaltered.
