NatureTM 100 Posted February 8, 2011 Share Posted February 8, 2011 So I'm starting to write up my stroboscopic guitar tuner project. I downloaded eagle, and went to add my first part, an hef4794bp shift register/led driver. I searched through eagle's built-in libraries, and googled a bit, but couldn't find the part. I'm completely new to eagle, and I'm not sure where to go from here. Should I just try to find a similar IC in the library and use that? Could it be that the part is out there and I'm just not finding it or I need to select a different library? Quote Link to post Share on other sites
JMLB 24 Posted February 8, 2011 Share Posted February 8, 2011 I was just in the same boat 2 days ago. I created my part from scratch. i used this as a guide http://www.instructables.com/id/How-to- ... e-CAD-too/ a few note though that I changed. the pads for my chip I left them on the default layer. He says he used smd to add them but I types pad. Also DON'T mess with the grid. It gets really annoying when you build your schematics because the wire need to snap to the grid and your pin for it to have a connection. Finally the wire he uses to make the shape of the chip, I put it on the tPlace layer NatureTM 1 Quote Link to post Share on other sites
GeekDoc 226 Posted February 9, 2011 Share Posted February 9, 2011 If you search Google for "Eagle CAD Tutorial" you'll find a bunch of written and video tutorials. iirc, SparkFun has some good ones. Quote Link to post Share on other sites
