#HL2.0.5 ready for testing. Click here Wiki is also updated to 2.0.5, use the Release .zip file for older docs.
HoodLoader2 is a CDC BootLoader with self reprogramming and USB-Serial function.
An Arduino Uno/Mega board has two Microcontroller of which one(16u2) is normally used for USB-Serial translation. But we can also use it as standalone AVR Microcontroller with (or without) USB functions as well.
HoodLoader2 gives you the option to reprogram the 16u2 of a normal Arduino Uno/Mega R3 with custom sketches. This means you can use the 16u2 as a normal USB AVR like a Leonardo. You have a full compatible USB-HID core, CDC Serial and you can also use the 7 i/o pins of the 16u2. The extended HID devices and USB-Core improvements of the HID Project also apply for the HoodLoader2.
The 16u2 is somehow limited in its functions but still a great addition if you know how to use it. It also compatible with FastLED and IRLremote(with PCINT) for example.
The great thing about this is that you actually have two fully Arduino compatible Microcontrollers in one Arduino Uno/Mega board – the board most of you already own. Your main MCU (328/2560) is still reprogrammable if you enter bootloader mode. All you need for this is a normal Arduino Uno/Mega R3 and some cables to install the new HoodLoader2. Please read the readme carfully to avoid any problems. You will find most of the answers to your questions already in the readme.

You have 3 versions you can download:
- The master includes all fixes to the current stable release. Download it by clicking download at the right. The online Wiki should have the newest documentation but might have some updated stuff which is only available in the dev tree.
- Download an offline version in releases. It's a snapshot of the current stable release but might have missed some updates that the current master branch has included. This also includes an offline version of the wiki. Offline versions will be available after some time when the official release is out.
- Select branch 'dev' to test the bleeding edge of this software. It might not work at all or has a lot of debugging stuff in it. Use the online Wiki to get the newest documentation. If the dev version gets near to a new release a note will be placed here, that you can test the new dev beta. Currently there is no beta available.
All documentation moved to the wiki page.
An offline snapshot is available in releases.

* Moved to Lufa Board definition (with a fix)
* Added HID-Project 2.2 compatibility
* Added boards.txt for Uno/Mega + HID-Bridge
* Improved Uno/Mega uploading (no double tab needed any more)
* Updated USB drivers for better PC side recognition
(Each USB core has a different PID + Windows driver)
* Fixed wrong PIDs in boards.txt
2.0.3 Release (28.01.2015)
* Added HID Project 2.1 board definition compatibility
* Fixed usb flag pass via boards.txt (instead of pins_arduino.h)
* Fixed 16u2 4 pin header pinout picture
* DFU burn bootloader fix
* HoodLoader2.0.3 released (minor firmware CDC identifier fix)
* Added 32u2 bootloader to the installation sketch as well
* Improved flash.bat file and included avrdude for windows
* Improved Readme instructions
* Updated USB drivers with 4 different PIDs
* Moved documentation to the wiki
2.0.2 Release (30.11.2014)
* HID Project 2.0 official released:
* Added Arduino IDE Integration for HoodLoader2
* See official changelog for more information.
* HoodLoader2.0.2 released (led off fix)
2.0.1 Pre-Release (29.11.2014)
* HoodLoader2.0.1 Release
* Better, full reset after bootloader execution with watchdog
* This fixes the "No-USB" workaround with the USB clock
* Fixed fuse bug
* Fixed magic key passed from Arduino core (HID Project)
* Changed some descriptor names, bugfix above freed some space
* Special case 57600 baud for compatibility with the ATmega328 bootloader TODO resolved (baud reserved for cdc)
* Reset of 328 when leaving Bootloader mode resolved (not possible to fix)
* _delay_loop_2() instead delay function resolved (saves 2 bytes, more confusing + inaccurate than useful)
* CPU_PRESCALE resolved (not needed for bootloader, watchdog will reset it anyways)
* Re enabled LOCK_BYTE_WRITE_SUPPORT function (due to flash improvements)
* Increased TX/RX EP_SIZE to 64 bytes
* Increased Serial->USB Buffer to 128 bytes
