Eagle files for LM4F120H5QR

[stick 0]

Hi!

 

Is there a reference design for board using LM4F120H5QR in case I want to create a custom board based on this chip? (Stellaris Launchpad is quite big for my project). Ideally in Eagle format.

 

Or at least is there a library that contains LM4F120H5QR part so I can create such reference design?

I have created an Eagle library for LM4F120H5QR part - see https://github.com/fabhack/eagle and grab fabhack.lbr if you want to play with this!

 

Comments and fixes are welcome! Also a reference design for minimalistic custom board would be very nice! :-)

Wow, thank you! I'm flattered! :-)

Congratulations, stick! I must get round to fixing the issues reported in my Launchpad library to see if I can earn an Eagle award too.

Should the Launchpad component be placed on the top or bottom of the PCB when creating a boosterpack? I guess there needs to be two inverted components if the component should be used both for top and bottom placement of a stellaris launchpad, or does eagle handle this for you?

Use the "mirror" tool to move component to the bottom layer.

The Launchpad library is designed to be with the LP on top. As RobG (sho knows ar more than me) says you can mirror it if required.

 

Any other questions about the LP library you can ask over on the relevant thread to avoid cluttering up this one.

I am using the Stellaris launchpad, trying to create a booster pack (breakout board) for a home automation project.  Till now I have only used a breadboard for prototyping.  Now I am trying to use Eagle to make a PCB, so I am a complete novice with Eagle.  I have been through the Sparkfun Eagle tutorial, and I have Stick's fabhack library installed in Eagle.

 

The launchpad component in the fabhack library looks like exactly what I need.  I can add it to a schematic and connect the pins to other components.  I can make a new board from the schematic and see all the wires, arrange my components, etc.  But then when I go to use auto rout I don't get any traces created between the launchpad and the other components.  

 

I get traces for connections from one pin of the launchpad to another pin of the launchpad.  And I get traces between all the other components except the launchpad.  But nothing between the launchpad the other components.

 

Any ideas?  Am I misunderstanding how to use this launchpad component?  Thanks so much.

EDIT: I can rout manually rout between the launchpad and other components.  But it seems like I must be doing wrong if I cannot auto route.

As a follow up, I found that if I removed the perimeter lines (wires) form the launchpad component (I edited the lbr file and just removed four lines from the component definition) I can auto route wires to a foot print larger than the physical launchpad board.  Not sure if this was the best way, but this does allow me to make my break out board much larger while still leveraging library.
