USB Mass Storage Class Host (usb_host_msc)

+//! +//! This example application demonstrates reading a file system from a USB mass +//! storage class device. It makes use of FatFs, a FAT file system driver. It +//! provides a simple command console via the UART for issuing commands to view +//! and navigate the file system on the mass storage device. +//! +//! The first UART, which is connected to the Tiva C Series virtual serial port +//! on the evaluation board, is configured for 115,200 bits per second, and +//! 8-N-1 mode. When the program is started a message will be printed to the +//! terminal. Type ``help'' for command help. +//! +//!
