摘要
研讨USB总线通用接口芯片CH375以及与单片机读写的基本方法,给出了其硬件电路设计,不使用CH375提供的子程序库,利用读写其扇区和自己的文件系统来读取U盘中的数据,实现单片机系统的大量数据存储,可实现与PC机系统快速交换数据。该方法简单,便于操作,成本低,通用性强,可靠性高等特点。
In the article introduced one kind of USB data interface chip CH375 and the basic method,and give the design of the hardware circuit,it＇s not use the subroutine library,use sectors read/write and our file system to read/write the data of the USB-Strick, achieve the mass of data storage through the microcintroller system,achieve exchange data at the high-speed.This method is simple,easy to operate,low cost,applied widely and high reliability.
