Hi All,
My first project in FPGA and USB. I'd like to implement CY7C680013 usb as an interface for JTAG + data port for FPGA board (Cyclone).
From my google/EDA research I already found a project to implement an usb_jtag .
Also CY7C68013 had (slave)FIFO that could be interesting for a data port.
Final usage will be data acquisition and transfer to PC.
I would like an advice from anyone that already made this USB uC works.
Already got the ICs, so forget about suggesting me to buy an usb-ready borad.
Regards from Buenos Aires,
Martin

I have the Cypress EZ-USB on my desk now. I use it to transfer data between Xilinx Spartan-3E FPGA & PC. It is not very simple to use. Try to use their GPIF for maximum throughput.
Using this IC to program the FPGA is my next plan.

ihearme, voho,
Thanks both for your reply.
ihearme,
Throughput is not an issue for me. Which soft/firm do you use for this?
Thansk for your help.
Martin

martingn,
I design the firmware base on the framework provided by Cypress on Keil compiler.
I develop the application software on Visual C++ using the CyAPI driver from Cypress also.
My project is to get huge amount of data from DDR2->FPGA->FX2->PC continuously. It took me a while to get all the pieces together because I couldn't understand their documentation well.
You can try several samples from Cypress for the start.
