pic mcu code:This application note describes the design and implementation of a USB Mass Storage Device (MSD) using a Secure Digital card, which should prove useful to developers of USB mass storage solutions. This application may be used as a stand-alone MSD or as a Secure Digital/Multimedia Card (SD/MMC) reader/ writer interface.

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.

USB、串口、并口是PC機和外設(shè)進行通訊的常用接口，但對于數(shù)據(jù)量大的圖像來說，若利用串行RS-232協(xié)議進行數(shù)據(jù)采集，速度不能達到圖像數(shù)據(jù)采集所需的要求；而用USB進行數(shù)據(jù)采集，雖能滿足所需速度，但要求外設(shè)必須支持USB協(xié)議，而USB協(xié)議與常用工程軟件的接口還不普及，給使用帶來困難。有些用戶為了利用標(biāo)準(zhǔn)并行口(SPP)進行數(shù)據(jù)采集，但SPP協(xié)議的150kb/s傳輸率對于圖像數(shù)據(jù)采集，同樣顯得太低。因此,為了采集數(shù)據(jù)量大的圖像數(shù)據(jù),本文采用了具有較高傳輸速率的增強型并行口協(xié)議(EPP)和FPGA，實現(xiàn)對OV7620CMOS圖像傳感器進行高速數(shù)據(jù)采集，它最高速率可以達到2Mb/s。

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.
