RS-485接口具有较强的抗干扰性，数据传输的距离较远，在一些应用中常常需要把RS-232标准的信号转换为RS-485的标准信号进传输。图中所示电路允许数据在RS-232/RS-485这两个不兼容的串行数据接口间传递。传输速度为480波特时，传输距离可达1750米。图中双RS-232收发器IC1将主机(PC)输出的RS-232电平转换为TTL电平，驱动高速RS-485收发器IC2 的输入，倒相器使IC2、IC3在受到起始位时被激活。-RS-485 trying to lay all the thoroughly bleed at the nose picking up the birthday 扰 fern cavity 强 ， Chu Huai basin cavity beat escapement for the birthday candle远Now ， Which instance, using Beckmannia中

本文以51单片机为例介绍如何扩展USB接口进行对U盘的读写，并详细介绍FAT16、FAT32文件系统的细节以及如何编码实现单片机对文件系统的常用操作，顺带提到一点关于U盘兼容性问题的解决经验。在这里单片机是host，U盘是slave。-In this paper, single-chip microcomputer 51 as an example on how to expand the USB interface on the U disk read and write, and details on FAT16, FAT32 file system and how to encode the details of the realization of single-chip microcomputer used for file system operations, mentioned in passing that on U disk experience compatibility problems. Here is a single-chip host, U disk is a slave.
