Linux 64-bit

Eagle requires a 32-bit environment which may or may not be installed in linux yet.
I have taken the step to istall the following libraries prior to running the eagle.run file from here

sudo apt-get install ia32-libs lib32z1 lib32z1-de

After this eagle installed without a problem.

Linux alt-click / alt-drag moving the window problem

The newer Linux window managers tend to use the alt-click or alt-drag combinations to move or re-size windows. This prevents us from using that same key in both Blender and Eagle.

tip about using alt-grid on ubuntu:

but also look into changing this behavior from the regular window manager. (as it is apparently not a keyboard shortcut...)

For Linux Mint 17, the following trick was used:

Designing circuits with Eagle

eagle_tool_commands.png

Open Eagle

• Select New Project
• Select New Schematic

Open library turn off all libraries, right click use none: scroll down to supply enable

• fab.lbr
• supply1.lbr
• rcl.lbr
• led.lbr
• v-reg.lbr

• Open library, click Use
• Download from the internet a library or select on in the computer the library that we will be using (e.g.
• fab.lbr[1]

• or the one from Sparkfun.lbr ([2] version 2011 ( right click on this link, save link as)

• SelectAdd, then you can open the library
  • (if you don't find your thing you could also click on "Use")

Starting new projects

• File -> New Project
• File -> New Schematic
• File -> Save As (filename.sch)

• Select the things you want to use and click Add to get the components.

• You can select different view by clicking on Board
• You can select object by right clicking them and selecting packning
• Connect objects by clicking Wire and make wire between objects.
• It can be good to make connections and get a sign for Ground and put where it should be GND.

Board view

• View Grid select the size of the grid, alternative grid could be around (0,025 inches)
• Move to move object or line.
• Delete to remove object or line and so on.
• Junction Connection point .
• Ratsnest Calculates calculate the airwires so that they show the shortest possible connections.

• • You can right click objects and select value to set values e.g. for capacitors or resistors
  • Right click on object and select properties to rename.
  • You can check out if you have connected the object by moving them.

• ERC Electrical rule check, search for errors.

Arrange objects

A tip for arranging objects

• Start with data signals, and do your power signals (GND and VCC the last).

Add

Check the design rules.

• Tools ->DRC -> Load-> Check

• Frame to make frame around the design.
• Arrange objects
• click Auto
  • Select Bottom N/A

If it is not as good as you wanted you can select lines, by right clicking them and select rip off

View-> Layer settings ->

• All ->Ok ( to check out if everything is within the board, also the layers that are not visible.
• None ->

and the turn on the layers you want to have.

• File -> Export image
  • resolution: 1200 dpi
  • Area: Full
• Monochrome: check.

Info about Circuits

• TX transmit
• DTR data terminal ready
• Rx Recieve
• Miso -master in slave out
• Mosi master out slave in
• sck system clock

• MOSI (3) GND (2) MISO (1) |
• -RESET (4) SCK (5)

Project 1

• First project could be to make schematic of this board and to add something to it, add (at least) a button and LED (with current-limiting resistor) to the serial echo hello-world board, check the design rules, and make it
  • See the layout for hello.ftdi.44

• Download libraries
  • fab.lbr[3]
  • atmel-new.lbr, Attiny 44 library

Materials used

• IC1 = ATtiny44_SOIC('IC1\nt44') -> see in fab.lbr
• R1 = R_1206('R1\n10k') -> See in fab.lbr
• C1 = C_1206('C1\n1uF') -> fab.lbr
• XTAL = Crystal 20 MHz -> search for crystal in fab.lbr
• FTDI connector (6 pin) ->search for ftdi in fab.lbr
• Header (2*3 pin) -> search for isp in fab.lbr
