gEDA-user: Footprint for an SMT chip resistor array
Hello fellow gEDA/PCB users, I wonder, does anyone have a footprint for an SMT chip resistor array with 4 isolated resistors? I don't know how those footprints are called (which is why I'm unsure what to look for), but such resistor arrays can be found on many many digital boards. I don't have a specific part picked out and I can use just about any part in the Digi-Key catalog with any reasonable footprint, so I'd like to reverse the problem of making the footprint for a part and look for an existing PCB footprint that I like and then pick a Digi-Key part that'll fit it. So, does anyone have a footprint for ANY SMT chip resistor array of the kind that I've described (8 pins, 4 resistors)? (Yes, I know that drawing footprints is not as scary as it seems, but again I'm completely flexible in my choice of parts and don't have any other basis for choosing my footprint, so why not make existing PCB footprints my choice criterion.)

gEDA-user: PCB viewport moving when seleting from torn-off menus?
I just built from CVS so I should be current. I'm using Lesstif. If I tear off the tools menu, drag it off to one side, then zoom in on the board, each time I select from the menu the viewport jumps in the direction of the menu (up/down/left/right depending on where the menu is on the desktop). I've done this in Cygwin/X, Xvnc and XFree86 on OSX. What's even stranger is that I'm not seeing any kind of "edge scroll" behavior otherwise, only when the menu moves me. Not all menus do it, but Tools does repeatably. -- Ben Jackson AD7GD <[EMAIL PROTECTED]> http://www.ben.com/ ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

I just built from CVS and I notice that I can repro my problem if I route on the wrong side.

Regarding the old thread (Mon, 05 Aug 2002) about inter page connectors (http://www.geda.seul.org/mailinglist/geda-dev54/ msg00053.html), I wrote a perl script which updates cross reference attributes. See quick help below. Anyone interested in giving it a try? _jP > ./geda-xref -h Usage: ./geda-xref [OPTIONS] designName -hHelp; this message Parses all schematic files and looks for net segments with an attribute 'netname=', and: - if no 'xref=' attribute is associated with the same net segment then add such attribute to the net segment - if a 'xref=' attribute is associated with the same net segment then fix its size, orientation, justification, color and location such that its value is visible next to the end of the net segment that is closer to the origin of the 'netname' attribute. This works best when the 'netname' attribute is placed with its origin near the end of the dangling net. - update the value of the 'xref=' attribute to show on which page the same 'netname' is being used: - If no other reference to this net is found anywhere in the design then the attribute is removed. - References to the same page are included. - Multiple instances on a given page are shown as a single page - Multiple pages are separated by a comma: firstPage,secondPage,... - Consecutive pages are shortened: firstPage-lastPage Assumes the following naming convention for schematic pages: designName_#.sch where # is the page number.
