Eagle 6.x has various Atmel parts, many look like correct package, but they all different in size. Can someone tell me if there's an existing part that has same foot print as ATTiny85 SOIC version?
ATTiny85 SOIC is "S8S1, 8-lead, 0.150" Wide Body, Plastic Gull Wing Small Outline (JEDEC SOIC)" with 1.27mm or .05 inches between pins. Any package with that outline could be used, you would just have to make connections correctly ignoring whatever the pin names are on the other device. I just don't know Eagle that well. In DipTrace it is very easy to copy an existing footprint for a different device with the same packaging and just rename the pins.
I managed to download a "ATTINY85V-10SU" library part from Farnell (Element 14). Register with them and there are Eagle libraries for quite a few of their stock items.
Thanks guys! I don't know any easy way to measure exact distances in Eagle so it's pretty impossible to see sizes of existing packages. I will get Element14's library!
On the board view, select View:Grid, change the top entry to 0.1mm.
Then you can move the cursor around and get readings from top to bottom, or side to side, and determine sizes.
At Newark.com (Farnell), you need to register before you can download eagle library zip files.
Unzip the file into your library file. There is usually a folder with a readme.txt and a .scr file.
From the eagle control panel (not the schematic view or board view), select Open:Library.
At the library screen, select File:Execute Script. Browse to the .scr file and open that. The new part symbol will open. Select File:Save As and browse to your library folder.
I have a separate eagle library folder from the Eagle/Libraries folder with these and my created libraries.
After that, go to your schematic, select Library:Use, browse to the folder and the newly saved library. Then Edit:Add, and scroll down to the new part.
