How to wire a Sparkfun's "Led Bar Graph" with Eagle EDA

marsstar
marsstar over 11 years ago

As I added the "Led Bar Graph" from Sparkfun's Eagle Library, that I downloaded, into my schematic on Eagle. I saw that it had only one input and one output (attached Pict. "Schematic view")

But I would like to light up the Led's individually. But however, after I imported it to the board view, from the schematic view, it suddenly has a single connection to Pin 2 (attached Pict. "Board view").

How can I wire up each of its 10 inputs separately (each led) to create a level meter. - As I mentioned, I only see a single input and output in the schematic view.

    I suspect the device has been created with each LED being a separate gate.

     

    Gates and use of 'Invoke is explained in the manual, found in the .doc

    folder of your installation.

     

    So in the schematic, right click on the solitary LED and select 'Invoke'

    from the context menu.

    You should see the remainder of the diodes you can place onto the

    schematic.

     

    All the best
