Change AVRISP project's timeout to be interrupt based again, but make the interrupt itself interruptable and use a seperate assembly file to hand-optimize the ISR code.

Removed the cast to uint16_t on the set baud rate in the USBtoSerial project, so that the higher >1M baud rates can be selected (thanks to Steffan).

Added WIN_LIBUSB_COMPAT compile time option to the AVRISP programmer project to make the code compatible with Windows builds of avrdude at the expense of AVRStudio compatibility.

More fixes to the AVRISP command timeout system so that it should no longer lock up while processing command no matter what the conditions.

AVRISP programmer project now has a more robust timeout system, allowing for a doubling of the software USART speed for PDI and TPI programming.

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.

Changed XPLAINBridge project to be both a USB to USART bridge and a PDI programmer, based on the state of a mode select pin.

Clean up and add more comments to the AVRISP-MKII project. Make sure the SPI_MULTI command handler supports multiple packet responses. Use slightly smaller/faster repeated indirect-load commands when retrieving the PDI target's memory CRCs.

Added command timeout to the AVRISP project so that incorrectly connected targets no longer freeze the device.

Removed string descriptors from the TeensyHID bootloader to reduce its size.

Combine AVRISP project TPI and PDI lib directories - these protocols use the same underlying XPROG wrapper for the host-to-programmer command wrapping.

Document the PDI programming routines implemented so far in the AVRISP project. Add ability to selectively disable ISP programming support in addition to the existing ability to disable PDI programming support.

Factor out all the ISP related code into a seperate ISPProtocol set of files in the AVRISP Clone programmer project, to clearly seperate out the programming protocols when PDI programming is implemented.

Rename the V2Protocol command handlers in the AVRISP project in preperation of XMEGA PDI programming support.

Doxygen fixes to \param directives to give data direction in all projects. Make HID item filtering routines clearer in the HID WithParser demos.

Increase AVRISP command timeout to 240ms up from 150ms to prevent some ISP commands from timing out too early.

Add check to the PROGRAM FLASH ISP and PROGRAM EEPROM ISP handler to return an explicit error when the host attempts to write more data than the device is able to buffer.

Make WaitWhileBusy function in the AVRISP project more explicit about how it sends and receives the busy check command.

Reduce size of PROGRAM FLASH ISP or PROGRAM EEPROM ISP buffer to 256 bytes to prevent blowing the stack on the smallest USB AVR models.

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.

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.
