After the single transaction waveforms are implemented in the GPIF Designer, the next step is to integrate the USB portion of the

overlying firmware with the GPIF Designer output to perform write and read operations to and from the external FIFO. To do this

a Firmware Frameworks project was copied and the code that performs the external FIFO operations was added to the TD_Poll()

function within FX2_to_extsyncFIFO.c (note that periph.c was renamed to something more meaningful here). Endpoint and GPIF

register initialization is performed in the TD_Init() function, which is also within FX2_to_extsyncFIFO.c. When you open up the

Keil uVision2 project for the FIFO example
