Symbols for 8-Pin AVR/PIC

Normally I open up the library manager and just create one, or just modify another similar component and sav it as a AVR, whatever

Why you waste your time with google instead of just drawing your own symbols, packages, and devices? And, no, I have no AVR/PIC, but if you are looking for MSP430s with metric dimensions (symbols and packages) I could help with my own home-brewed library...

Yep I'm lazy :) Seriously, I take your point.

It was more that I have a number of devices to do (more than the ones I mentioned) and I hoped to find a reliable source of Eagle libraries that had devices in them that are more recent than mid-2005. I'm quite willing to share my own libraries, I just get sick of having to create a whole bunch of symbols every time I start a new project.

Oh, well.

It's a little more irritating if you have to make a symbol for something like Philips' LPC3xxx (sic) in BGA with 320 balls.

Hi, Peter.

I usually create my own. I've attached one for the Tiny13 below. Save this file as a *.scr file, open the library editor and run this script. IIRC, the SOIC-8 package it also creates has a slightly shorter pad than the one already in the atmel.lbr file.

I think you'll see it's not too hard, and I particularly prefer to script, because the accuracy is much greater.

From the note below, check the font used for the text - it needs to be vector to print properly. This script doesn't explicitly set the default, so you might end up with something else.

Cheers, Richard
