Mass Storage Device (MSD) class are devices that appear like drives when plugged into a host. Examples of these types of devices are thumbdrives (memory sticks), external USB hard disks, or external USB CD drives.
MSD drivers can be found in nearly all operating systems and requires no driver installation on most systems.
This framework includes several examples examples of MSD examples using different physical storage media. The MSD implementation in this release uses the Microchip Memory Disk (MDD) File System as the physical layer.

This section lists the files required for use with the device stack. These files should be included in any project using the MSD function driver In addition to these files additional files may be required from the Microchip MDD File System Library for the physical storage function calls (SD-SPI.c, etc). Please refer to the section discussing the LUN_FUNCTIONS type definition for more details about configuring the library to work with different physical layers in the MDD File System Library. |
