Communication between FPGA(spartan-3) with USB !?

[lythanhthuan]

cy7c68001 interfaced with fpga

I programming VHDL to commicate FPGA with USB ,but that's not easy,Can you help me ?

hi,

what kind of usb chip do you use? (Philips, Cypress ...)
which mode do you want to etablish commmunication :
master ? (usb controller drives datas to and from FPGA)
or slave ? (usb controller waits datas from the FPGA)

and the usb side, bulk mode? isochronous or interrupt mode? number of endpoints ...

regards

I think you have to need another USB chip between FPGA and Usb interface

look at CY7C68013A or CY7C68001 from Cypress. High speed.
