void USB_FPGA::setUSB ( iUSB_Driver * ud ) [inline, virtual]

Implements iUSB_FPGA.

int USB_FPGA::downloadConfigFile ( string file ) [virtual]

The FPGA config will need a different implementation for each different FPGA type.

Implements iUSB_FPGA.

Reimplemented in XILINX_XS3.

int USB_FPGA::configStart ( void )

Start the FPGA configuration.

int USB_FPGA::configWrite	(	byte *	b,
		int	len
	)

Write the configuration bits to the FPGA.

This isn't the most effecient way, currently using control writes (limited to 12Mbits/second). Should change to use EP1 (think this can do 2.0 High Speed, 480Mbits/second). Need to update the 8051 code. 8051: 1. Set mode, start config 2. Poll Endpoint 1 for config data 3. After all data sent, send end config command
