USB接口芯片CH376在专用控制系统中的应用

摘要

In view of the lack of dedicated control system U disk interface problems, presents a design scheme of adding the USB interface in the control system. The system general structure was introduced and gives schematic circuit diagram and program flow chart of mono-chip computers (MCU) access USB flash disk. The results show that the design is low cost, universal, easy application and high reliability, and fits most MCU based control systems or embedded systems for the implementation of USB flash disk interface functions.%针对专用控制系统缺乏U盘接口的问题，介绍一种在专用控制系统中增加USB接口功能的设计方案。介绍系统总体结构，给出系统电路原理图和单片机读写U盘的程序流程。结果表明：该方案具有成本低、通用性强、可靠性高等特点，可方便地集成到各种专用控制系统和嵌入式系统中，实现USB接口和U盘读写功能。
