Re: [Xylo-SDR] Eurocard Cyclone II PCB

["Phil Harman" <pvharman@arach.net.au>]

Leon,

Thanks for taking this up!  Just one question, one of the nice features of 
the Xylo board is the support software i.e. FPGAconf.exe. This makes 
programming the FPGA, using I2C , loading USB drivers on the PC etc very 
easy for beginners like me. We also don't need to program the FX2 to do any 
of this.

I know that Phil C is look  at using LibUSB 
http://libusb-win32.sourceforge.net/
as an alternative.  What I am getting round to is are we going to be able to 
get equivalent software for the Cyclone II board?
