When I installed the Front Panel software on a new computer from the CD I got with an XEM3001 I purchased in march 2008 I realized there are two versions of the host interface vhdl (okLibrary.vhd):
One in C:\Program Files\Opal Kelly\FrontPanel\XEM3001v2\Xilinx
the other in C:\Program Files\Opal Kelly\FrontPanel\FrontPanelHDL\XilinxISE82
I tried to start a project with the first one, but got nowhere (not even the .ucf file matches). I finally found the second one, and things seem to work fine.
What is that other version?
