This document provides guidelines for integrating a discrete high speed USB host controller onto a fourlayer desktop motherboard. The material covered can be broken into three main categories: Board design guidelines, EMI/ESD guidelines and front panel USB guidelines. Section 1.1 Background provides an explanation of the routing experiments and testing performed to validate the feasibility of 480 Megabits per second on an actual motherboard. Section 7 contains a design checklist that lists each design recommendation described in this document. High speed USB operation is described in the USB 2.0 Specification (http://www.usb.org/developers/docs.html).

This a simple bootloader for AT91SAM7{S,X}{64,128,256} processors. It permits you to download new code to the device over USB. This bootrom is installed at address 0x00000000 in the ARM, which means that it is the first piece of code to execute after reset. At startup, it waits for a few seconds to see if the downloader is trying to connect. If not, then the bootloader gives up control and jumps to your program. If the downloader is trying to connect, then the bootloader receives the new program over USB and writes it into flash.

This directory contains the memtest 8051 firmware for the Anchor Chips EZ-USB chip. The purpose of this software is to test the different memory segments in the Ez-Usb chip. This example will output the string "good" on the 7 segment LED if the mem test passes, or it will output the first address where the memtest fails.

通用串行总线(USB)是一种新兴的计算机外围串行通信接口标准，与常用的计算机接口(如串口、并口等)相比，通用串行总线(Universal Serial Bus，USB)具有热插拔、即插即用、数据传输可靠、扩展方便、低成本等优点。从问世以来，它得到了广泛的应用，一方面已成为当前计算机必备的接口之一，同时也被广泛地应用于嵌入式系统设计中。 从1994年USB 0．7出现开始，USB实施者论坛(Implementation Forum)先后定义了USB 0．8、0．9、1．0、1．1、2．0以及USB OTG等规范，以及各种不同的设备类规范。其中USB1．1规范目前正逐步广泛应用，而USB2．0和USBOTG作为USB协议的更新和扩展，也将使USB占领更广的外设

NAME Control_AT24Cxx This collection of routines allows an AT89C2051 microcontroller to read and write the AT24Cxx family of serial CMOS EEPROMS. This version of the code is compatible only with the AT89C2051 due to the location of the data buffer and stack in RAM. The code may be modified to work with the AT89C1051 by relocating or resizing the buffer and stack to fit into the smaller amount of RAM available in the AT89C1051. Note that the minimum size of the buffer is determined by the page size of the AT24Cxx.
