Me, for example. Former coworkers of mine, for example. It would be awfully nice if it could handle PCI-X though. Just a single (selectable) high-speed analog signal would also be very, very nice. The resolution doesn't have to be great (4-bits?). I've had trouble with a card due to a bad combination of a motherboard that really wasn't happy with two PCI-X cards on the same bus, verilog code that reacted a tad slower than would've been preferable, and some layout/electronics on the board that was a tiny little bit too bad. > For this > purpose, aesthetics are useful only as clues that make it easier to > use the program. I am almost entirely in agreement with that. I would add that aesthetics also make the user experience nicer, just like car doors that make the right sound when you close them (there are actually sound engineers who work on things like that!). > Has anyone written any code for this yet? I have written quite a bit of code for parsing VCD files, representing digital signals in memory (and writing a VCD file back out), and GUI code for viewing them. And lots of code to make the program integrate nicely with Gnome and to a certain extent any freedesktop.org environment. The program is not complete but there's not much left to do before it becomes useful. I was going to add support for something like this PCI analyzer to bølge anyway for a hobby project of mine. Part of that project involves a simple 40MHz 8-channel logic analyzer with a USB interface built from an 8051, some RAM chips (interleaved) and some counters and latches. It should be possible to do everything with 1984-era electronics, save for the USB connector. > I recommend this book to anyone who designs anything: > > http://www.amazon.com/Design-Everyday-Things-Donald-Norman/dp/0465067107/sr=8-1/qid=1168964534/ref=pd_bbs_sr_1/002-4137434-1839212?ie=UTF8&s=books I second that recommendation. I would supplement it with "Don't make me think!". -Peter _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
