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.

*
* 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.
*
* 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.
*
* Note that this design currently has the following limitations:
* - No reversed/shorted target connector detection and notification
Spell check all source files once again to find any typos.
15 years ago
* - A separate header is required for each of the ISP, PDI and TPI programming protocols that the user wishes to use

* On AVR models with an ADC converter, AVCC should be tied to 5V (e.g. VBUS) and the 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 5V 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.

* In addition, the AVR's XCK pin will generate a .5MHz clock when SPI programming is used, to act as an external
* device clock if the fuses have been mis-set. To use the recovery clock, connect XCK to the target AVR's XTAL1
* pin, and set the ISP programming speed to 125KHz or below.
