* \section SSec_Description Project Description: \r
*\r
- * This is a virtual serial port to soft-UART converter, for use on the Atmel XPLAIN boards. This project replaces the firmware\r
- * preloaded onto the XPLAIN's onboard AT90USB1287 microcontroller to act as a a UART-to-USB bridge between the device and the\r
- * host. When inserted, the device will enumerate as a regular COM port on the host, which can then be opened and data exchanged\r
- * between the XMEGA and Host as if the XMEGA was connected directly to the host's serial port.\r
+ * This project serves a dual purpose. When loaded into the USB AVR on the XPLAIN board, it will act as either a USB to Serial\r
+ * converter for the XPLAIN's hardware USART (at a speed of 9600 baud), or an AVRStudio compaible PDI programmer for the XMEGA.\r
+ * This project replaces the firmware preloaded onto the XPLAIN's onboard AT90USB1287 microcontroller.\r
*\r
- * After running this demo for the first time on a new computer, you will need to supply the .INF file located in this demo\r
+ * When power to the board is applied, the TDI pin (pin 9) of the USB AVR's JTAG port is read. If the pin is left high, the device\r
+ * will enumerate as a regular COM port on the host, which can then be opened and data exchanged between the XMEGA and Host as if\r
+ * the XMEGA was connected directly to the host's serial port. If the pin is pulled low by shorting it to GND (pin 10), the device\r
+ * will enumerate as an AVRISP-MKII to the host, so that the XMEGA can be reprogrammed by AVRStudio or other compatible software\r
+ * such as avrdude.\r
+ *\r
+ * After running this project for the first time on a new computer, you will need to supply the .INF file located in this project\r
* project's directory as the device's driver when running under Windows. This will enable Windows to use its inbuilt CDC drivers,\r
* negating the need for custom drivers for the device. Other Operating Systems should automatically use their own inbuilt CDC-ACM\r
* drivers.\r
*\r
+ * This project relies on files from the LUFA AVRISP-MKII project for compilation.\r
