* you wish to enlarge this space and/or change the AVR model, you will need to edit the BOOT_START and MCU

* This bootloader is compatible with the open source application AVRDUDE, or Atmel's AVRPROG.
* 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.

* This bootloader enumerates to the host as a DFU Class device, allowing for DFU-compatible programming
* software to load firmware onto the AVR.
*
* This bootloader is compatible with Atmel's FLIP application. However, it requires the use of Atmel's
* DFU drivers. You will need to install Atmel's DFU drivers prior to using this bootloader. 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
* 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

*
* \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>.
*
* As an open-source option, this bootloader is also compatible with the Linux Atmel USB DFU Programmer
* software, available for download at <a>http://sourceforge.net/projects/dfu-programmer/</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.
*
* If SECURE_MODE is defined as true, upon start-up the bootloader will be locked, with only the chip erase
* function available (similar to Atmel's DFU bootloader). If SECURE_MODE is defined as false, all functions
* are usable on start-up without the prerequisite firmware erase.
* \section Sec_HostApp Host Controller Application
*
* This bootloader is compatible with Atmel's FLIP utility on Windows machines, and dfu-programmer on Linux machines.
*
* 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.
* \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>.
*
* <b>NOTE:</b> 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.
* The following example loads a HEX file into the AVR's FLASH memory using dfu-programmer:
* \code
* dfu-programmer at90usb1287 erase flash Mouse.hex

* \section Sec_HostApp Host Controller Application
*
* Due to licensing issues, the supplied bootloader is compatible with the HalfKay bootloader protocol designed

* 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:
