摘　　要：基于目前在数据采集设备和仪器仪表等嵌入式系统中,数据交换多采用串行口或以太网等方式的现状,本文介绍了一种以U盘为存储介质的U盘控制器设计方案,并给出了系统电路原理图和单片机读写U盘的程序流程。该方案以USB接口芯片CH376和单片机为核心,具有成本低、通用性强、可靠性高等特点,可方便的集成到各种测控系统中,解决了串口、网络通信方式需要布线施工、成本高、移动性差的问题。Now UART and Ethernet are widely used in application-embedded systems. Based on MCU and CH376, this paper introduces a design and implementation to control USB flash disk, and provides schematic diagram of hardware and part of program, gives detailed introductions to their principles and control-methods. It is proved to have several advantages such as low cost, easy application and stable running. This solution fits the application especially in measuring system and data acquisition equipment.
