Added  ATTR_NON_NULL_PTR_ARG() attributes to the class drivers to improve user code reliability by disallowing explicit NULL pointers as pointer parameters in function calls where the parameter must not be NULL.

Disabled building of the Demos/Host/ClassDriver directory until Host Mode Class drivers are complete to prevent build errors in the meantime.

Fixed Programmer's Notepad project file to reflect new location of AVRISP project.

Make AVRISP project build again - fix incorrect preprocessor directive in V2Protocol.c, fix makefile LUFA_PATH.

Partial Commit: Remove now empty Projects\Incomplete directory and add the new AVRISP project to the Projects directory makefile.

Finished preliminary AVRISP project - all V2 protocol commands now work correctly for basic operations.

Fixed AVRISP V2 Protocol handler for the READ_FLASH_ISP and READ_EEPROM_ISP handler - can now correctly read back device data. Programming command handler is still broken, although first page is written correctly to FLASH in paged write mode.

Updated Benito project -- added hardware interrupt and software buffering for serial data reception to prevent missed characters, condensed pulse generation counters into a struct for clarity.

Added check to CDC_Device_BytesReceived() to ensure 0 is returned when device is not enumerated to a host.

Move AVRISP project's V2Protocol_DelayMS() function to be static inline, as it is now very minimal. Added extra project doxygen documentation.

Fix endianness of LOAD_ADDRESS command data, add correct PROGRAM_FLASH_ISP/PROGRAM_EEPROM_ISP polling and endpoint bank clearing, add hardware delays/timeouts to the V2 Protocol handler in the AVRISP project.

More additions to the PROGRAM_FLASH_ISP and PROGRAM_EEPROM_ISP commands, although neither work correctly yet.

Added dummy RESET_PROTECTIONS handler to prevent the Atmel driver from crashing when the command returns an UNKNOWN_COMMAND error code.

Added PROGRAM_FLASH_ISP and PROGRAM_EEPROM_ISP handler code to the V2 Protocol handler in the AVRISP project, programming complete checks not yet complete.

Fix to V2 Protocol for Fuse/Sig/Lock byte read -- off by one error on the array when writing back the response from the device.

FLASH/EEPROM reading and writing currently broken and unfinished, respectively.

Added V2 protocol handlers for the READ and WRITE memory commands in the AVRISP project. Finished READ command handler, skeleton WRITE handler implemented.

Added Load Extended Command functionality to the LOAD ADDRESS V2 Protocol command handler for devices with more than 64KB of memory.

Fixed AVRISP programmer demo -- can now connect to a target and read/write Sig/Lock/Fuse/OSCCAL bytes successfully.

Changed SPI_Init() to allow for the clock polarity and data sample modes to be set.

Changed Dataflash_Init() to no longer call SPI_Init() automatically.

Added V2Protocol handlers to the AVRISP project to enter/exit programming mode, and read/write fuses, lockbits, OSCCAL and Signature bytes.

Added ShutDown functions for all hardware peripheral drivers, so that peripherals can be turned off after use.

Fix up references to functions in the Endpoint/Pipe documentation.

Change spinloop in the AVRISP project Unknown V2 Protocol Command handler to use Endpoint_WaitUntilReady() instead to prevent infinite loops.

Moved out the handling of V2 Protocol parameters to a seperate set of files. Added parameter privellages, so that an error can be returned to the host when trying to perform a get/set value action on a parameter without the correct privellages.

Added documentation of the makefile CDEFS values to the MagStripe project.

Fixed invalid data being returned when a GetStatus request is issued in Device mode with an unhandled data recipient.

Fix up Programmers Notepad Project file to show new Projects directory layout. Remove now moved AVRISP project from the Projects directory makefile.

Move AVRISP Programmer project to a new Unfinished subdirectory of Project while it is under development.

Enhancements to the AVRISP Programmer project to attempt to get AVRStudio to communicate with the device.

Added new Endpoint_SetEndpointDirection() macro to set the current endpoint direction for bidirectional endpoints.

Renamed internal USB_INT_ENDPOINT_SETUP macro to USB_INT_RXSTPI to fit in with the rest of the interrupt vector macros.

Fix USBtoSerial device demos -- ensure the UDR1 register contents is read in under all circumstances which fire the ISR, so that the receive complete interrupt is cleared correctly to prevent freezes.

Added new EVENT_USB_Device_StartOfFrame() event, controlled by the new USB_Device_EnableSOFEvents() and USB_Device_DisableSOFEvents() macros to give bus-synchronised millisecond interrupts when in USB device mode.

Adjust endpoint polling intervals for HID demos, to make them compliant with the 10ms minimum polling period for Low Speed devices.

Minor updates to the unfinished SideShow demo for clarity.

Added unfinished MassStorageHost class driver demo.

SetIdle requests to the HID device driver with a 0 idle period (send changes only) now only affect the requested HID interface within the device, not all HID interfaces.

Apply correct fix to the HID report parser for PUSH items - current HID item attribute stack was being copied in the wrong direction.

Fixed HID report parser not resetting the FEATURE item count when a REPORT ID item is encountered.

Minor documentation fixes.
