1st of all I hope, I am posting this thread in right category.
I am trying to interface CY7C68013A (FX2LP) USB controller from Cypress Semiconductor with spartan3 FPGA,
Purpose is to make a GUI which can transfer data between PC and FPGA.
Any suggestion, precautions or help would be really great.
I recommend looking at the **broken link removed**, which provides FX2LP firmware and a cross-platform host library for communicating with it. Have a look at some of the Digilent Spartan-3* development board designs for physical details on hooking up the FX2LP (e.g. the Digilent NEXYS2).
