Eagle CAD question

2012-06-13 by phabib

I'm learning Eagle CAD and trying to design a general purpose touch panel and LCD display that I could use as a user interface.

The touch IC I wanted to use (Atmel QT2100) was too new to be in a library so I created a new part by using an existing 32pin footprint and defining the rest of the stuff.  Not 100% straightforward, but it was good practice.

I want to use a New Haven Display NHD-C12832A1Z for the display.  I found someone on another list who posted a .sch file and a .brd file that uses the display.  I haven't been able to figure out how to go from there to adding the part to either a library so I can use it, or directly to my drawing.

Does anyone here have some pointers or am I going to have to define my own part from scratch?

Thanks.

First, if you are "learning Eagle CAD", you might as well get used to creating your own parts.  If a part is wrong, your design will be wrong so you need to take responsibility for this.  It is amazing how many parts are wrong, even from "reputable" sources such as the Eagle libraries themselves.

Or, if you want to use the part in the schematic / board files you have found, assuming the author is OK with this, then Google something like "Eagle cad export library".

Have to concur with Graham on this. Always roll your own or at least triple
check library parts and better still import them into your own libraries
after triple checking them.

 

Messed up PCB designs make good coffee mug coasters but rather expensive
ones at that! :o)

 

I use Altium Designer and have found issues with the "professional"
libraries supplied. If I roll my own or make a mistake in checking, at least
the fault is mine but after having done quite a few designs, I can now say
this is all in the past since I change my attitude to creating my own. :o)

 

Once you get comfortable in doing library parts it quite a quick and
painless exercise to make your own.

Thank you both for taking the time to answer, and for the pointer to how to export.

I agree about the value of doing your own stuff.  I did create my own part for the IC, and I was hoping to save myself some work for the display.

This is the first time I try to do a board since laying out with black tape on mylar back in high school.
