* \section SSec_Description Project Description:
|
|
|
|
|
*
|
|
|
|
|
* 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
|
|
|
|
|
* converter for the XPLAIN's hardware USART (at a speed of 9600 baud), or an AVRStudio compaible PDI programmer for the XMEGA.
|
|
|
|
|
* This project replaces the firmware preloaded onto the XPLAIN's onboard AT90USB1287 microcontroller.
|
|
|
|
|
*
|
|
|
|
|
* 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
|
|
|
|
|
* 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
|
|
|
|
|
* 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
|
|
|
|
|
* will enumerate as an AVRISP-MKII to the host, so that the XMEGA can be reprogrammed by AVRStudio or other compatible software
|
|
|
|
|
* such as avrdude.
|
|
|
|
|
*
|
|
|
|
|
* After running this project for the first time on a new computer, you will need to supply the .INF file located in this project
|
|
|
|
|
* project's directory as the device's driver when running under Windows. This will enable Windows to use its inbuilt CDC drivers,
|
|
|
|
|
* negating the need for custom drivers for the device. Other Operating Systems should automatically use their own inbuilt CDC-ACM
|
|
|
|
|
* drivers.
|
|
|
|
|
*
|
|
|
|
|
* This project relies on files from the LUFA AVRISP-MKII project for compilation.
