[Xcircuit-dev] pcb library

[Bryce Denney]

I'm getting ready to make an xcircuit library of common pcb parts, and the
first on my list is headers: 1x2, 1x4, 1x6, 2x2, etc.  The only question
is what pin numbering scheme to use for dual row headers.  Is there any
kind of standard for this?  Does anybody have a preference?

a)
09 10 11 12 13 14 15 16
01 02 03 04 05 06 07 08

b)
01 02 03 04 05 06 07 08
09 10 11 12 13 14 15 16

c)
02 04 06 08 10 12 14 16
01 03 05 07 09 11 13 15

d)
01 03 05 07 09 11 13 15
02 04 06 08 10 12 14 16

IMHO, c and d make sense if you're using IDC connectors to ribbon cable,
but otherwise a&b are more intuitive.  No, I don't want to make one for
every possible combination. :)

I'll also be making a matching layout symbol for all these parts, using
pcb for linux.  I haven't figured out how to make a library in pcb,
yet.

Please let me know if anyone else is working on this, or is interested in
working on it with me.

Regards,
Bryce
