*
* 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.
+ * 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 promted, direct your OS to install Atmel's AVRISP-MKII drivers provided with AVRStudio.
*
+ * Note that this design currently has several limitations:
+ * - Minimum target clock speed of 500KHz due to hardware SPI used
+ * - No VTARGET detection and notification
+ * - No reversed/shorted target connector detection and notification
+ *
* \section SSec_Options Project Options

* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
