摘要
本文介绍一种基于SL811HS的单片机读写U盘的系统。系统由单片机、USB接口控制器、高速RAM等设备组成,解决了多数数据采集设备、工控机及嵌入式系统没有安装USB标准接口,不能读写U盘的问题。重点分析系统的原理及传输协议,给出了硬件、软件的实现方法。
This paper introduces a system of MCU Read & Write Udisk based on SL811HS. This system is composed of MCU, USB interface control unit and high-speed RAM, solving the problem of USB standard interfaces being uninstalled in most data collection equipment, work controller and built-in system and Udisk not being read and written. It emphasizes the analysis of the principle of the system and communication protocol, and presents the method of realizing the hardware and software.
