Hi Dario,
I also purchased the vidor 4000 to learn FPGA programming. Seeing that usb blaster emulation is not supported yet is bit of a let down.
I went to Libraries - Arduino Reference to check the details about the VidorPeripherals library but its not listed there. Is there a documentation for it somewhere that I can refer to?
Also if you can share where I can look into the source code of these libraries that will be great. I think that can help me to see if I can make a custom FPGA library as per my needs.
Thanks & Regards
