We are currently considering this interface in a custom embedded controller design but based on your recommendations we probably need to reassess that decision. We were intending to use the parallel port through a super io chip on a custom designed board but it sounds like we should go with an ISA or PCI bus interface to get real-time performance at 1mbit baud rate. Our application requires the full 1mbit baudrate continuous for 100msec to 200msec intervals. FYI, I remember discussions about real-time problems with the PCAN dongle: https://mail.gna.org/public/xenomai-help/2007-03/msg00185.html See also: https://mail.gna.org/public/xenomai-help/2007-03/msg00183.html Can't remember where I got that information from, maybe from PEAK PCAN support. But that user did not have the problems you reported. Maybe it's hardware related. Wolfgang.
