Slowly building up a collection of parts we use here ... This file includes some library parts from microbuilder.eu Most of 'em are either Eagle parts that I've changed a little to make them easier to solder, some are 'handmade' and a few are from microbuilder.eu Its released into the Public Domain - that means you can do whatever you want. We'd like it if you kept the author email/url in the part description, just so we can be alerted if there are errors. Enjoy!
I noticed a odd thing in the adafruit.lbr when I used the XTAL-4 device. It didn't work in my design, so I looked into it, and it seems that the pins are wrongly assigned.
In the library the pads in the footprint are numbered (always top-view)
1 2
4 3
and X1 = 1, X2 = 3. But in every Datasheet (and my bought crystals) (like http://www.datasheetpro.com/pdf/NihonDempaKogyo/cu24_NX3225SA_e1.pdf) the pads are numbered
4 3
1 2
and X1 = 1, X2 = 3, meaning that the adafruit lib expects the crystal to be between 4 and 2, but it is between 1 and 3. Hope you get it fixed before others make the mistake of not checking it themselves before
I may be totally wrong that there are crystals out there where they are between 4 and 2, but at least I couldn't find them in europe.
