USB code for DEnano inteface Board

I’ve been trying to write a Python script to receive the IQ data from the DE0 interface board (like the FFTViewer app). I’ve tried using libUSB on Win7, but haven’t been able to read the data. I noticed in the FFTViewer code that on win32 it uses the Cypress API (CyAPI) and on linux it uses the libusb. Is there a reason why it doesn’t use libusb on the windows side?

Hello Gibson,

We used native cypress drivers because we were able to get wanted data speed throughout USB interface. Probably by today Cypress supplies native drivers for Linux as well.
