Hi DJ, -----Oorspronkelijk bericht----- Van: [email protected] [mailto:[email protected]] Namens DJ Delorie Verzonden: zondag 27 december 2009 4:12 Aan: [email protected] Onderwerp: gEDA-user: blue sky ideas - written down finally
I took the time to document my ideas about heavy vs light symbols and the pin mapping problem: http://www.delorie.com/pcb/component-dbs.html http://www.delorie.com/pcb/pin-mapping.html I got tired of looking it up in the mail archives or referencing it as "some time in the past...". If you remember me saying more about these than I wrote down, and can find it in the mail archives, let me know so I can add to them. DJ _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user Good thing to write these ones up, maybe even put them on a wiki page on gpleda.org so others can join in on the fun and contribute by adding/extending/correcting/elaborating etc. On the pin mapping subject I miss an example of the power pins of a rail-to-rail opamp, just to nail these troublemakers down as well (sometimes I get Vss hitched to ground instead of the negative voltage rail). An interesting article about this subject lives here: http://en.wikipedia.org/wiki/IC_power_supply_pin The syntax for defining swapable pins and (swapable) gates is something that one could probably work out quite easily, and feels "natural" to me :) BTW: there are two D2 pins in your RAM chip example. On the subject of the database, it's a bazillion parts ot there, only to be done on a "what-you-need-is-what-you-put-in-the-dbms-first" basis. This has to be a distributed effort in some way, gedasymbols.org is a good starting point, it's to big a job for one individual person. And even for all contributors themselves it's like scratching their own itch first: 1) do what is neccessary, 2) do what is possible, And the impossible is done by doing 1) and 2) :) Kind regards, Bert Timmerman. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
