int USBP_PBRD_V01::testXferLoopback ( int x )

TEMP Test function, use to test xfer to FX2.

Todo:: Add FPGA loopback to test USB xfer rates.

Todo:: Add some kind of verification that loopback code is loaded.

Todo:: Configure for LoopBack Mode.

int USBP_PBRD_V01::testFPGAXferSpeed ( void )

With the first version of the FPGA, the FPGA logic will copy the byte recieved to the LEDs.

This can be used to see how fast data can be transferred to the FPGA, read by the FPGA and written to the LEDs.

int USBP_PBRD_V01::PyReadData ( BP::list & pyList )

Read Data from the USB Board.

The USBP boards have two different data paths. One is a straight FIFO data path intended for streaming data. The other is the wishbone interface.

This interfaces to the straight ("streaming") endpoint. From Python's point of view want to be sending and receiving lists.

int USBP_PBRD_V01::PyWriteData ( BP::list & pyList )

Write Data to the USB Board.

The USBP boards have two different data paths. One is a straght FIFO data path intended for streaming data. The other is the wishbone interface.

Important, need to send more than one byte to the cypress endpoints?? This is definetly true given emperical evidence, not sure if this is a limitation of the FX2 device or my understanding of the chip. This is ok shouldn't ever be sending a single, only doing that for testing.
