Help?

Hi, I am new to this program. I have tried everything and can't figure out

why nothing I do is working.

 

I need a simple adapter board. I watched videos and everything. I am trying

to simply make a small board that has 42 holes for a m27c160 eprom to fit a

36 hole board.

 

I have went here http://schematicpal.com/ and downloaded the eprom

M27C801-100B1 it shows two boxes the left red box and the right green

circles in the black box. I can only place the red box in the schematic

when I need the other one to just place the holes for me. When I click on

circles they are not circles but pads, I need holes!

 

Plus the eprom clearly has 42 legs yet the only Library file you can place

in is missing majority of pins. This blows my mind it's not even accurate?

You go to the board view and magically it shows the entire chip but

completely useless as it will not let you run traces, that has to be done

in the schematic where they don't exist!!!

 

I have tried drawing circles "holes" manually but when I switch to board

view it does not bring them in? I tried grouping the 42 circles together as

that is what I need for the 27c160 eprom but it does nothing.

 

I can't believe how difficult this is. I want to order these boards but I

need a gerber file. I could whip this thing out in paint in like 10

minutes, here I have wasted countless hours trying to decipher this program

that will not do anything I want it to.

 

I think learning a new language would be easier them deciphering this

program.

  • Are you sure you're using the right software for your particular desired workflow?

    It doesn't sound like it.

    EAGLE is all about schematics and then building a circuit board from there.

    Schematics parts often don't use the same number of pins as a physical part.

    If you just want to lay 'holes', then there may be other software out there that

    you could be using - EAGLE would be extreme overkill for that -

    although it could do it, you'd have to plough through the user documentation -

    it's not intended to a MS Paint replacement and so the workflow isn't as simple

    with EAGLE.

    By the way, your part number M27C801-100B1 really is a 32-pin device,

    not a 42-pin device.

    I know the M27C801-100B1 is a 32 dip, however it is the chip I currently

    use right now for my boards. I need to move up to the bigger chip which is

    why I need the adapter board made. I only chose that from the library as it

    was all there was and I knew the hole sizes and spacing was what I needed.

     

    I was hoping I could just lay that chip out twice or something and over lap

    the pins or just add the extra holes needed. I'm just going to call it a

    day and pay somebody to do this. I really wanted to do it myself but I

    can't waste all this time into this program.

     

    As far as other programs, maybe but I'm pretty burnt out and annoyed right

    now that I don't think I want to waste any more time learning another

    program that may not be correct for what I need done.

     

    Thanks for the reply. It's nice to get some input from someone.
