43.10. TINYUSB HOST MSC U DISK EXPLORER

43.10.1. 概述

本示例工程展示U盘的访问操作（建议：U盘的格式化参数为FAT32/32KB）。

MCU作为文件管理器，在Console中可通过指令访问U盘，支持的指令如下：

* help
       Print list of commands
* cat
       Usage: cat [FILE]...
       Concatenate FILE(s) to standard output..
* cd
       Usage: cd [DIR]...
       Change the current directory to DIR.
* cp
       Usage: cp SOURCE DEST
       Copy SOURCE to DEST.
* ls
       Usage: ls [DIR]...
       List information about the FILEs (the current directory by default).
* pwd
       Usage: pwd
       Print the name of the current working directory.
* mkdir
       Usage: mkdir DIR...
       Create the DIRECTORY(ies), if they do not already exist..
* mv
       Usage: mv SOURCE DEST...
       Rename SOURCE to DEST.
* rm
       Usage: rm [FILE]...
       Remove (unlink) the FILE(s).

43.10.2. 硬件设置

使用USB Type-C线缆连接PC USB端口和PWR DEBUG端口
使用USB Type-C转USB-A线缆连接U 盘和开发板USB0端口或者USB1端口

43.10.3. 运行现象

当工程正确运行后，将显示U盘的信息：

TinyUSB Host MassStorage Explorer Example
A MassStorage device is mounted
IS917    innostor rev 1.00
Disk Size: 7500 MB

在console中输入回车，将出现 > 提示符，此时可进行U盘操作。输入help指令，将显示支持的指令列表。
输入help指令，将显示支持的指令列表：
