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).

Make sure that long reads are aborted early if the connection times out while waiting on more bytes in the AVRISP MKII clone project.

Make sure that the NVM bus/controller busy waits in the AVRISP MKII clone project abort properly if a timeout occurs while waiting for a response.

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 .5MHz recovery clock to the AVRISP programmer project when in ISP programming mode to correct mis-set fuses.

Fixed AVRISP project not extending the command delay after each successful page/word/byte program.

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.

Add first draft of the TPI NVM commands for reading, writing and erasing a target. Needs testing when physical access to a part is available.

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.

Complete combining of PDI and TPI target communication code files, stub out TINY NVM controller functions.

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

Make seperate ISP, PDI and TPI folders in the AVRISP project Lib subdirectory to hold each protocol's files.

Add new HotmailNotifier project, which changes a LED's colour based on the user's unread email count as sent from Windows Live Messenger.

Fix project text files to refer to "project" instead of "demo".

Complete initial working revision of PDI programming in the AVRISP project (XMEGAs can now be programmed by the firmware).

Fix a bug in the Still Image Host Class driver where the returned block status code was being truncated.

Add programming support to the AVRISP project's PDI programming mode; paged memory writes are not currently functional.

Fix error in AVRISP programmer when repeatedly using PDI mode via the hardware USART due to the SendByte routine not clearing the Transmit Complete USART flag.

Add Doxygen documentation to the completed portions of the PDI programming protocol in the AVRISP project.

Use the PDI REPEAT instruction in the PDI programmer code to reduce protocol overhead and greatly improve transfer throughput. Switch bit-bang USART in the AVRISP project to Timer 1, so that Timer 0 can be used for hardware timeouts while waiting for the NVM bus or controller to become ready.

Fix NVM commands so that memory reads and CRC generations now work correctly using unoptimized PDI commands.

Split out NVM access code in the AVRISP project into a seperate NVMTarget.c source file and header. Make NVM register accesses use the NVM base address as set by the host, rather than using the fixed value from the XMEGA datasheet.
