Description: 功能：在AT91SAM7-EK 板上实现用串口（DBGU）操作mmc /sd 上的ucfs文件系统，支持fat文件格式。实现了文件（夹）建立，读写，删除，格式化，容量显示等基本功能，有需要的朋友可以继续添加新功能 。实现了ucos接口，要用到其他的存储介质更容易。因为有现成的ucfs接口驱动。详细情况见文件包中的说明 。
不是高手，做的不好的地方请大家谅解。-functions : In AT91SAM7-EK board realized using serial (DBGU) Operating mmc / sd text on the ucfs Ware System, fat file format support. Implementation of the document (SCH) Establishing literacy, delete, format, capacity display basic functions, need friends can continue to add new features. OUT Interface realized that we had to use other storage media more easily. Because of off-the-shelf ucfs driven interface. See details of the documents included in the note. Not masters, do the bad things that please understanding.

Description: Designing and programming a USB mass-storage device or embedded USB
host involves a variety of interfaces, protocols, and structures.
Every USB mass-storage device must support two interfaces:
• A USB device interface to enable the device to communicate with a PC
or other USB host.
• An interface between the device’s microcontroller or other CPU and the
storage media. Flash-memory cards typically use the Serial Peripheral
Interface (SPI), MultiMediaCard bus, SD-Card bus, or a bus derived
from the ATA interface or PC-Card bus. Hard drives typically use the
ATA parallel interface.
A USB mass-storage device must implement these protocols and structures:
• Generic USB protocol. Every USB device must respond to requests sent
by the USB host and other events on the bus.

Description: 串口转以太网目前可以采用串口转以太网模块来实现，变得非常简单易用，但是在该技术中出现的一些新问题、使用误区需要引起注意。串口转以太网并不是简单传输媒介的变化，而是串口到TCP/IP的协议转化。其中关系到的关键技术包括：TCP/IP的工作模式问题、串口分帧技术、9位技术。这里详细分析这些串口转网口的技术。-Serial to Ethernet can currently be used serial to Ethernet module to achieve, very easy to use, but the technology of the emergence of some new problems, the use of misunderstanding needs attention. Serial to Ethernet is not a simple transmission media change, but the serial to TCP/IP protocol conversion. Which is related to the following key technologies: TCP/IP working mode, serial frame technology, the 9 technology. Here a detailed analysis of the serial port to network technology.
