Use the framework provided GlobalInterruptEnable() function instead of the AVR8/XMEGA specific sei() macro, for future demo/project portability.

AppConfigHeaders: Move out the last of the demo/app configurations into new AppConfig.h header files.

Add branch for the conversion of demos to use standard C header files for configuration, rather than makefile defined macros.

Run wspurify script on /trunk/ and /branches/ C source files, to remove any trailing whitespace at the end of each line.

Removed the ENDPOINT_DESCRIPTOR_DIR_* macros in favour of the shorter ENDPOINT_DIR_* macros, which can now be used with both Endpoint_ConfigureEndpoint() and in the device descriptors.

Remove custom PIDs on the Class Driver Audio device demos and revert back to the original Audio PIDs, as the low level and class driver demo versions are now descriptor compatible once again.

Added missing Audio class control request definitions.

Added support for the Audio class GET STATUS request so that it is correctly ACKed when sent by the host.

Renamed all low level Endpoint_Read_*, Endpoint_Write_* and Endpoint_Discard_* functions to use the number of bits instead of a symbolic size (Byte, Word, DWord) so that the function names are applicable and correct across all architectures.

Renamed all low level Pipe_Read_*, Pipe_Write_* and Pipe_Discard_* functions to use the number of bits instead of a symbolic size (Byte, Word, DWord) so that the function names are applicable and correct across all architectures.

Add static keyword to all project globals whose scope should be restricted to the same module as they are declared in.

Tighten up the HID class bootloader code slightly, document that it currently exceeds 2KB of bootloader space for all models other than the Series 2 USB AVRs.

Fixed calculation of timer register reload values derived from F_CPU; must subtract one from the division result for the compare value to be correct.

Change AVRISP-MKII rescue clock speed to 4MHz to ensure that a 125KHz ISP speed works regardless of the target's fuses (i.e. DIV8 set).

Renamed the EVENT_USB_Device_UnhandledControlRequest() event to EVENT_USB_Device_ControlRequest() as it is now fired before the library request handlers, not afterwards.

Changed over www.fourwalledcubicle.com links to the new www.lufa-lib.org redirect domain, including the new aliased links for LUFA-related pages such as the various download/source control mirrors and support lists.

Changed AudioInput and AudioOutput demos to reload the next sample via an interrupt rather than polling the sample timer.

All USB class drivers are now automatically included when LUFA/Drivers/USB.h is included, and no longer need to be seperately included.

All LowLevel demos changed to use the constants and types defined in the USB class drivers.

Changed all Device mode LowLevel demos and Device Class drivers so that the control request is acknowledged and any data transferred as quickly as possible without any processing inbetween sections, so that long callbacks or event handlers will not break communications with the host by exceeding the maximum control request stage timeout period.

Removed complicated logic for the Endpoint_ConfigureEndpoint() function to use inlined or function called versions depending of if the given bank size is a compile time constant, as the compiler does a better job of optimizing with basic code.

Changed over all device demos to use a clearer algorithm for the configuring of the application's endpoints.

Add svn:eol-style property to source files, so that the line endings are correctly converted to the target system's native end of line style.

USB_Init() no longer calls sei() to enable global interrupts - this must now be done in the user application once all init code has run.

Fixed compilation error in the AudioInput demos when MICROPHONE_BIASED_TO_HALF_RAIL is defined (thanks to C. Scott Ananian).

Minor documentation cleanups.

Make sure HID class driver uses properly cast pointers when writing to the report buffer.

Added explicit ADC channel masks for the standard set of ADC channels, as the single-ended channel MUX masks are not equal to the channel number on some AVR models. Changed demos to use the new channel masks when using the ADC driver.

Fixed Endpoint_Write_Control_Stream_* functions not sending a terminating IN when the given data length is zero.

Fix up demo documentation device compatibility list to be as general as possible to reduce changes required as Atmel releases more devices within the same USB AVR series.

Renamed all library events to properly seperate out Device and Host mode events. Changed the firing conditions for some events to ensure that events are fired by their own USB mode only.

Remove VBUS events - not needed as the library takes care of VBUS detection and feedback on supported AVRs via the USB_Device_Connected and USB_Device_Disconnected events.

Fixed incorrect Host state assignment in the incomplete BluetoothHost demo.

Added new Endpoint_ClearStatusStage() convenience function to assist with the status stages of control transfers.

Removed vague USB_IsConnected global - test USB_DeviceState or USB_HostState explicitly to gain previous functionality.

Removed USB_IsSuspended global - test USB_DeviceState against DEVICE_STATE_Suspended instead.

Fixed possible enumeration errors from spinloops which may fail to exit if the USB connection is severed before the exit condition becomes true.

Add explicit guards to all device mode tasks to ensure the device is connected and configured before running the task, to prevent any user tasks from locking up the main USB task if the device has not been properly configured.

MIDI device demo no longer blocks if a note change event is sent while the endpoint is not ready.

Move new Class Driver powered demos to a new ClassDriver subdirectory, re-add old low level demos to a LowLevel subdirectory.
