43.10. TINYUSB HOST MSC U DISK EXPLORER

43.10.1. Overview

  • This sample project demonstrates U disk access operations (Recommendation: U disk formatting parameters FAT32/32KB).

    UDisk_Format

  • MCU acts as a file manager, where you can access the U disk through commands in the Console. Supported commands are as follows:

* 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. Hardware Setup

  • Use a USB Type-C cable to connect the PC USB port and the PWR DEBUG port

  • Use a USB Type-C to USB-A cable to connect the U disk and the development board USB0 port or USB1 port

43.10.3. Running the example

  • When the project runs correctly, it will display the U disk information:

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

  • After pressing Enter in the console, the > prompt will appear, and then you can operate the U disk. Input the help command to display the supported command list.
