|

*
|
||||
* Combined Mass Storage and Keyboard demonstration application. This gives a
|
||||
* simple reference application for implementing a dual class USB Mass Storage
|
||||
* and USB HID Keyboard device using the basic USB UFI and HID drivers in all
|
||||
* modern OSes (i.e. no special drivers required).
|
||||
*
|
||||
* On start-up the system will automatically enumerate and function as an
|
||||
* external mass storage device (which may be formatted and used in the same
|
||||
* manner as commercial USB Mass Storage devices) and a USB keyboard.
|
||||
*
|
||||
* You will need to format the mass storage drive upon first run of this
|
||||
* demonstration - as the device acts only as a data block transport between
|
||||
* the host and the storage media, it does not matter what file system is used,
|
||||
* as the data interpretation is performed by the host and not the USB device.
|
||||
*
|
||||
* Keys on the USB keyboard can be pressed by moving the board's Joystick.
|
||||
*
|
||||
* The USB control endpoint is managed entirely by the library using endpoint
|
||||
* interrupts, as the INTERRUPT_CONTROL_ENDPOINT option is enabled. This allows for
|
||||
* the host to reset the Mass Storage device state during long transfers without
|
||||
* the need for complicated polling logic.

||||
