Help drawing a schematic

Other Parts Discussed in Thread: EK-TM4C123GXL

Hi, I recently designed a project that involved interfacing a Tiva TM4C123G board with a display and keypad. I was wanting to draw up my final design for a blog to show how it was wired together but i'm not sure of the best way. Is there any software I can use that will give me a design like this?

Regards

    Hello Harry

    As a student, Eagle CAD is suggested as they give students Cad tool license for a very low cost and limited trial version for free.

    There are several options
    At the high end with lots of capabilities there are programs like Altium Designer.

    I'm partial to Cadsoft Eagle (although I don't know how well its fared under Newark) which has both free and purchase versions. It has Schematic capture, layout, rule checking for both schematic and layout (ERC/DRC), an autorouter and fairly extensive scripting capability. It has better linkage between schematic and layout than I had seen in the costlier packages I'd used.

    There is also at least one open-source package (KiCAD?) but I can't comment on their capabilities or ease of use.

    I have used Eagle, I still have it installed however I have struggled to find the Tiva TM4C123G in there - I found an old post through here which said all CAD programs weren't supported including Eagle

    This was what I found, under Design section near the bottom. It doesn't seem to open with Eagle for me

    You could check EAGLE's forums (if they still exist) or just create the part yourself. It's not difficult and it's a good exercise to do so.

    I prefer to generate my own parts in any case, that way I get the proper checking and I fall prey to my own mistakes not that of some developer in the CAD company.

    The command line shows strength over the GUI for this kind of task although I can imagine part wizards that might help.

    Not surprising, those are not EAGLE files (the readme says created with Pads (which I think Altium has bought). Someone needs to change that description. Amit can you direct that to someone appropriate?

    Hello Harry,

    If you wish to generate the CAD symbols then you can generate tool specific device CAD files from the following link
