* Firmware for an AVRStudio compatible AVRISP-MKII clone programmer. This project will enable the USB AVR series of
* microcontrollers to act as a clone of the official Atmel AVRISP-MKII programmer, usable within AVRStudio. In its
* most basic form, it allows for the programming of 5V AVRs from within AVRStudio with no special hardware other than
* the USB AVR and the parts needed for the USB interface. If the user desires, more advanced circuits incorporating
* level conversion can be made to allow for the programming of 3.3V AVR designs.
* most basic form, it allows for the programming of AVRs at the programmer's VCC voltage from within AVRStudio with

*
* This device spoofs Atmel's official AVRISP-MKII device PID so that it remains compatible with Atmel's AVRISP-MKII
* drivers. When prompted, direct your OS to install Atmel's AVRISP-MKII drivers provided with AVRStudio.

* On AVR models with an ADC converter, AVCC should be tied to 5V (e.g. VBUS) and the \c VTARGET_ADC_CHANNEL token should be
* set to an appropriate ADC channel number in the project makefile for VTARGET detection to operate correctly. On models
* without an ADC converter, VTARGET will report a fixed 5 V level at all times.
* without an ADC converter, VTARGET will report a fixed 3.3 V level at all times.

* While this application can be compiled for USB AVRs with as little as 8KB of FLASH, for full functionality 16KB or more
* of FLASH is required. On 8KB devices, ISP or PDI/TPI programming support can be disabled to reduce program size.
