* \section Sec_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 compatible 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 by connecting to the board as if it was an Atmel AVRISP-MKII programmer.
|
|
*
|
|
* After running this project in serial bridge mode 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 virtual serial drivers, negating the need for custom drivers for the device. Other Operating Systems should
|
|
* automatically use their own inbuilt CDC-ACM drivers.
|
|
*
|
|
* In serial bridge mode, the UART baud rate can be altered through the host terminal software to select a new baud rate - the default
|
|
* baud is 9600. Note that parity, data bits and stop bits are fixed at none, eight and one respectively can cannot be altered. Changes
|
|
* to the connection's parity, data bits or stop bits are ignored by the firmware. As the serial link between the controllers on the
|
|
* XPLAIN is software emulated by the USB AVR, not all baud rates will work correctly.
|
|
*
|
|
* This project relies on files from the LUFA AVRISP-MKII project for compilation.
