Simon Its not a firewire issue. On the computers I test, you can run DPCLat without installing the firewire card and the latencies will show about the same as after you put the card in. The only difference in performance is whether your firewire card is sharing an interrupt with something and what that might be.
Its not very difficult. Especially if you are running an AMD Phenom II-based system. Their northbridge seems to work much better than Intel's for real time stuff for some reason! 73 Neal Campbell Abroham Neal Software www.abrohamnealsoftware.com (540) 645 5394 NEW PHONE NUMBER Amateur Radio: K3NC Blog: http://www.abrohamnealsoftware.com/blog/ DXBase bug reports: email to ca...@dxbase.fogbugz.com Abroham Neal forums: http:/www.abrohamnealsoftware.com/community/ On Thu, Mar 25, 2010 at 2:06 PM, Simon HB9DRV <si...@hb9drv.ch> wrote: > I think it would be OK on most platforms were only your program running; > users then install lots of other 'stuff' and demand that it runs at the > same > time, this can cripple a good 'real-time' solution.
