+ *
+ *  The following list indicates what microcontrollers are compatible with this demo.
+ *
+ *  - Series 7 USB AVRs (AT90USBxxx7)
+ *  - Series 6 USB AVRs (AT90USBxxx6)
+ *  - Series 4 USB AVRs (ATMEGAxxU4)
+ *  - Series 2 USB AVRs (AT90USBxx2, ATMEGAxxU2)
+ *
+ *  \section Sec_Info USB Information:
+ *
+ *  The following table gives a rundown of the USB utilization of this demo.
+ *
+ *  <table>
+ *   <tr>
+ *    <td><b>USB Mode:</b></td>
+ *    <td>Device</td>
+ *   </tr>
+ *   <tr>
+ *    <td><b>USB Class:</b></td>
+ *    <td>Communications Device Class (CDC)</td>

+ *   </tr>
+ *  </table>
+ *
+ *  \section Sec_Description Project Description:
+ *
+ *  This bootloader enumerates to the host as a CDC Class device (virtual serial port), allowing for AVR109
+ *  protocol compatible programming software to load firmware onto the AVR.
+ *
+ *  Out of the box this bootloader builds for the USB1287, and will fit into 4KB of bootloader space. If
+ *  you wish to enlarge this space and/or change the AVR model, you will need to edit the BOOT_START and MCU
+ *  values in the accompanying makefile.
+ *
+ *  When the bootloader is running, the board's LED(s) will flash at regular intervals to distinguish the
+ *  bootloader from the normal user application.
+ *
+ *  \section Sec_Installation Driver Installation
+ *
+ *  After running this bootloader for the first time on a new computer, you will need to supply the .INF
+ *  file located in this bootloader project's directory as the device's driver when running under Windows.
+ *  This will enable Windows to use its inbuilt CDC drivers, negating the need for custom drivers for the
+ *  device. Other Operating Systems should automatically use their own inbuilt CDC-ACM drivers.
+ *
+ *  \section Sec_HostApp Host Controller Application
+ *
+ *  This bootloader is compatible with the open source application AVRDUDE, Atmel's AVRPROG, or other
+ *  applications implementing the AVR109 protocol, which is documented on the Atmel website as an application
+ *  note.
+ *
+ *  \subsection SSec_AVRDude AVRDUDE (Windows, Mac, Linux)
+ *
+ *  AVRDude is a free, cross-platform and open source command line programmer for Atmel and third party AVR
+ *  programmers. It is available on the the Windows platform as part of the "WinAVR" package, or on other systems
+ *  either from a build from the official source code, or in many distributions as a precompiled binary package.
+ *
+ *  To load a new HEX file with AVRDude, specify "AVR109" as the programmer, with the allocated COM port. On Windows
+ *  platforms this will be a COMx port name:
+ *  \code
+ *  avrdude -c AVR109 -p at90usb1287 -P COM0 -U flash:w:Mouse.hex
+ *  \endcode
+ *
+ *  On Linux systems, this will typically be a /dev/ttyACMx port name:
+ *  \code
+ *  avrdude -c AVR109 -p at90usb1287 -P /dev/ttyACM0 -U flash:w:Mouse.hex
+ *  \endcode
+ *
+ *  Refer to the AVRDude project documentation for additional usage instructions.
+ *
+ *  \section Sec_Options Project Options
+ *
+ *  The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
+ *
+ *  <table>
+ *   <tr>
+ *    <td>NO_BLOCK_SUPPORT</td>
+ *    <td>Makefile LUFA_OPTS</td>
+ *    <td>Define to disable memory block read/write support in the bootloader, requiring all reads and writes to be made
+ *        using the byte-level commands.</td>
+ *   </tr>
+ *   <tr>
+ *    <td>NO_EEPROM_BYTE_SUPPORT</td>
+ *    <td>Makefile LUFA_OPTS</td>

+ *    <td>NO_FLASH_BYTE_SUPPORT</td>
+ *    <td>Makefile LUFA_OPTS</td>
+ *    <td>Define to disable FLASH memory byte read/write support in the bootloader, requiring all FLASH reads and writes
+ *        to be made using the block-level commands.</td>
+ *   </tr>
+ *   <tr>
+ *    <td>NO_LOCK_BYTE_WRITE_SUPPORT</td>
+ *    <td>Makefile LUFA_OPTS</td>

+ *
+ *  \section Sec_Compat Demo Compatibility:
+ *
+ *  The following list indicates what microcontrollers are compatible with this demo.
+ *
+ *  - Series 7 USB AVRs (AT90USBxxx7)
+ *  - Series 6 USB AVRs (AT90USBxxx6)
+ *  - Series 4 USB AVRs (ATMEGAxxU4)
+ *  - Series 2 USB AVRs (AT90USBxx2, ATMEGAxxU2)
+ *
+ *  \section Sec_Info USB Information:
+ *
+ *  The following table gives a rundown of the USB utilization of this demo.
+ *
+ * <table>
+ *  <tr>
+ *   <td><b>USB Mode:</b></td>
+ *   <td>Device</td>
+ *  </tr>
+ *  <tr>
+ *   <td><b>USB Class:</b></td>
+ *   <td>Device Firmware Update Class (DFU)</td>

+ *   <td>Full Speed Mode</td>
+ *  </tr>
+ * </table>
+ *
+ *  \section Sec_Description Project Description:
+ *
+ *  This bootloader enumerates to the host as a DFU Class device, allowing for DFU-compatible programming
+ *  software to load firmware onto the AVR.
+ *
+ *  Out of the box this bootloader builds for the USB1287, and should fit into 4KB of bootloader space. If
+ *  you wish to enlarge this space and/or change the AVR model, you will need to edit the BOOT_START and MCU
+ *  values in the accompanying makefile.
+ *
+ *  When the bootloader is running, the board's LED(s) will flash at regular intervals to distinguish the
+ *  bootloader from the normal user application.
+ *
+ *  \section Sec_Installation Driver Installation
+ *
+ *  This bootloader is designed to be compatible with Atmel's provided Windows DFU class drivers. You will need to
+ *  install Atmel's DFU drivers prior to using this bootloader on Windows platforms. If you are using a 64 bit Windows
+ *  OS, you will need to either disable the driver signing requirement (see online tutorials for details) or use a
+ *  digitally signed version of the official Atmel driver provided by a third party AVR user at
+ *  <a>http://www.avrfreaks.net/index.php?module=Freaks%20Academy&func=viewItem&item_id=2196&item_type=project</a>.
+ *
+ *  \note This device spoofs Atmel's DFU Bootloader USB VID and PID so that the Atmel DFU bootloader
+ *        drivers included with FLIP will work. If you do not wish to use Atmel's ID codes, please
+ *        manually change them in Descriptors.c and alter your driver's INF file accordingly.
+ *
+ *  \section Sec_HostApp Host Controller Application
+ *  
+ *  This bootloader is compatible with Atmel's FLIP utility on Windows machines, and dfu-programmer on Linux machines.
+ *
+ *  \subsection SSec_FLIP FLIP (Windows)
+ *
+ *  FLIP (Flexible In-System Programmer) is a utility written by Atmel, and distributed for free on the Atmel website.
+ *  The FLIP utility is designed to assist in the bootloader programming of a range of Atmel devices, through several
+ *  popular physical interfaces including USB. It is written in Java, however makes use of native extensions for USB
+ *  support and thus is only offered on Windows.
+ *
+ *  To program a device using FLIP, refer to the Atmel FLIP documentation.
+ *
+ *  \subsection SSec_DFUProgrammer dfu-programmer (Linux)
+ *
+ *  dfu-programmer is an open-source command line solution for the bootloader programming of Atmel devices through a
+ *  USB connection, using the DFU protocol, available for download at <a>http://sourceforge.net/projects/dfu-programmer/</a>.
+ *
+ *  The following example loads a HEX file into the AVR's FLASH memory using dfu-programmer:
+ *  \code
+ *  dfu-programmer at90usb1287 erase flash Mouse.hex
+ *  \endcode
+ *
+ *  \section Sec_Options Project Options
+ *
+ *  The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
+ *
+ *  <table>
+ *   <tr>
+ *    <td><b>Define Name:</b></td>
+ *    <td><b>Location:</b></td>
+ *    <td><b>Description:</b></td>
+ *   </tr>
+ *   <tr>
+ *    <td>SECURE_MODE</td>
+ *    <td>BootloaderDFU.h</td>
+ *    <td>If defined to true, the bootloader will not accept any memory commands other than a chip erase on start-up, until an
+ *        erase has been performed. This can be used in conjunction with the AVR's lockbits to prevent the AVRs firmware from
+ *        being dumped by unauthorized persons.</td>

+ *  \section SSec_Description Project Description: 
+ *
+ *  This bootloader enumerates to the host as a HID Class device, allowing for device FLASH programming through
+ *  the supplied command line software, which is a modified version of Paul's TeensyHID Command Line loader code
+ *  from PJRC (used with permission). This bootloader is deliberatley non-compatible with the properietary PJRC
+ *  HalfKay bootloader GUI; only the command line interface software accompanying this bootloader will work with it.
+ *  
+ *  Out of the box this bootloader builds for the USB1287, and will fit into 2KB of bootloader space for the
+ *  Series 2 USB AVRs (ATMEGAxxU2, AT90USBxx2) or 4KB of bootloader space for all other models. If you wish to
+ *  enlarge this space and/or change the AVR model, you will need to edit the BOOT_START and MCU values in the
+ *  accompanying makefile.
+ *
+ *  \section Sec_Installation Driver Installation
+ *
+ *  This bootloader uses the HID class driver inbuilt into all modern operating systems, thus no additional drivers
+ *  need to be supplied for correct operation.
+ *
+ *  \section Sec_HostApp Host Controller Application
+ *
+ *  Due to licensing issues, the supplied bootloader is compatible with the HalfKay bootloader protocol designed
+ *  by PJRC, but is non-compatible with the cross-platform loader GUI. A modified version of the open source
+ *  cross-platform TeensyLoader application is supplied, which can be compiled under most operating systems. The
+ *  command-line loader application should remain compatible with genuine Teensy boards in addition to boards using
+ *  this custom bootloader.
+ *
+ *  Once compiled, programs can be loaded into the AVR's FLASH memory through the following example command:
+ *  \code
+ *  hid_bootloader_cli -mmcu=at90usb1287 Mouse.hex
+ *  \endcode
+ *
+ *  \section SSec_Options Project Options
+ *
+ *  The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
+ *
+ *  <table>
+ *   <tr>
+ *    <td>

+ *  basic USB Audio 1.0 drivers in all modern OSes (i.e. no special drivers
+ *  required).
+ *
+ *  On start-up the system will automatically enumerate and function as a 
+ *  USB microphone. By default, the demo will produce a square wave test tone
+ *  when the board button is pressed. If USE_TEST_TONE is not defined in the
+ *  project makefile, incoming audio from the ADC channel 1 will be sampled
+ *  and sent to the host computer instead.
+ *
+ *  When in microphone mode, connect a microphone to the ADC channel 2.
+ *
+ *  Under Windows, if a driver request dialogue pops up, select the option
+ *  to automatically install the appropriate drivers.
+ *
+ *  \section Sec_Options Project Options
+ *
+ *  The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.

+ *
+ *  Audio demonstration application. This gives a simple reference
+ *  application for implementing a USB Audio Output device using the
+ *  basic USB Audio 1.0 drivers in all modern OSes (i.e. no special drivers
+ *  required).
+ *
+ *  On start-up the system will automatically enumerate and function
+ *  as a USB speaker. Outgoing audio will output in 8-bit PWM onto
+ *  the timer 3 output compare channel A for AUDIO_OUT_MONO mode, on
+ *  timer 3 channels A and B for AUDIO_OUT_STEREO and on PORTC as a signed
+ *  mono sample for AUDIO_OUT_PORTC. Audio output will also be indicated on
+ *  the board LEDs in all modes. Decouple audio outputs with a capacitor and
+ *  attach to a speaker to hear the audio.
+ *
+ *  Under Windows, if a driver request dialogue pops up, select the option
+ *  to automatically install the appropriate drivers.
+ *
+ *  \section Sec_Options Project Options

+ *
+ *  Dual Communications Device Class demonstration application.
+ *  This gives a simple reference application for implementing
+ *  a composite device with dual CDC functions acting as a pair
+ *  of virtual serial ports. This demo uses Interface Association
+ *  Descriptors to link together the pair of related CDC
+ *  descriptors for each virtual serial port, which may not be
+ *  supported in all OSes - Windows Vista is supported, as is
+ *  XP (although the latter may need a hotfix to function).
+ *
+ *  Joystick actions are transmitted to the host as strings
+ *  through the first serial port. The device does not respond to
+ *  serial data sent from the host in the first serial port.
+ *
+ *  The second serial port echoes back data sent from the host.
+ *
+ *  After running this demo for the first time on a new computer,
+ *  you will need to supply the .INF file located in this demo
+ *  project's directory as the device's driver when running under
+ *  Windows. This will enable Windows to use its inbuilt CDC drivers,
+ *  negating the need for custom drivers for the device. Other
+ *  Operating Systems should automatically use their own inbuilt
+ *  CDC-ACM drivers.
+ *
+ *  \section Sec_Options Project Options
+ *
+ *  The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
+ *
+ *  <table>
+ *   <tr>
+ *    <td>
+ *     None
+ *    </td>

+ *  OSes (i.e. no special drivers required). By default it accepts and sends up to 8 byte reports
+ *  to and from a USB Host, and transmits the last sent report back to the host.
+ *
+ *  On start-up the system will automatically enumerate and function as a vendor HID device.
+ *  When controlled by a custom HID class application, reports can be sent and received by
+ *  both the standard data endpoint and control request methods defined in the HID specification.

+ *  OSes (i.e. no special drivers required). It is boot protocol compatible, and thus
+ *  works under compatible BIOS as if it was a native keyboard (e.g. PS/2).
+ *
+ *  On start-up the system will automatically enumerate and function as a keyboard
+ *  when the USB connection to a host is present. To use the keyboard example,
+ *  manipulate the joystick to send the letters a, b, c, d and e. See the USB HID
+ *  documentation for more information on sending keyboard event and key presses. Unlike
+ *  other LUFA Keyboard demos, this example shows explicitly how to send multiple key presses
+ *  inside the same report to the host.

+ *  application for implementing a composite device containing both USB Keyboard
+ *  and USB Mouse functionality using the basic USB HID drivers in all modern OSes
+ *  (i.e. no special drivers required). This example uses two separate HID
+ *  interfaces for each function. It is boot protocol compatible, and thus works under
+ *  compatible BIOS as if it was a native keyboard and mouse (e.g. PS/2).
+ *
+ *  On start-up the system will automatically enumerate and function
+ *  as a keyboard when the USB connection to a host is present and the HWB is not
+ *  pressed. When enabled, manipulate the joystick to send the letters
+ *  a, b, c, d and e. See the USB HID documentation for more information
+ *  on sending keyboard event and key presses.
+ *
+ *  When the HWB is pressed, the mouse mode is enabled. When enabled, move the
+ *  joystick to move the pointer, and push the joystick inwards to simulate a
+ *  left-button click.
+ *
+ *  \section Sec_Options Project Options

+ *
+ *  Keyboard/Mouse demonstration application, using a single HID interface. This gives
+ *  a simple reference application for implementing a multiple HID report device
+ *  containing both USB Keyboard and USB Mouse functionality using the basic USB HID
+ *  drivers in all modern OSes (i.e. no special drivers required). This example uses a
+ *  single HID interface that is shared between the two functions.
+ *
+ *  On start-up the system will automatically enumerate and function as a keyboard when
+ *  the USB connection to a host is present and the HWB is not pressed. When enabled,
+ *  manipulate the joystick to send the letters a, b, c, d and e. See the USB HID
+ *  documentation for more information on sending keyboard event and key presses.
+ *
+ *  When the HWB is pressed, the mouse mode is enabled. When enabled, move the joystick
+ *  to move the pointer, and push the joystick inwards to simulate a left-button click.
+ *
+ *  \section Sec_Options Project Options
