Introduction to EAGLE – Part 1 – Control panel

This article is part of a tutorial dedicated to EAGLE. The reader may consult the other parts of the tutorial by following this link: Introduction to EAGLE
Eagle stands for Easily Applicable Graphical Layout Editor. It is an electronic CAD software manufactured by CadSoft Computer GmbH, a German company, since 1988. This software is provided with, among other, a schematic capture editor, a PCB (Printed Circuit Board) layout editor, an auto-router, a Computer-Aided Manufacturing (CAM)… It supports Windows, Linux and Mac OS X. This tutorial has been prepared under version 6.5.0 / Ubuntu 12.04 LTS

Control panel

When EAGLE is started, the following window appears on the screen,this is the control panel, the EAGLE starting window.ControlPanelOn the left hand side of the window the user manage existing and new projects and can get an overview about the libraries and settings :

  • Libraries: this entry lists libraries of components, each component is composed of a schematic and a footprint linked together.
  • Design Rules: the user can tune the parameters relevant to the board and its manufacture.
  • User Language Programs: this is C-like programs that can be used for a variety of tasks. It can be used, for example, to modify your project and automize certain tasks.
  • Scripts: the user can execute sequences of commands that are stored in a script file. It provides the ability to customize the program according to your own wishes (assign keys,
    load pc board shapes, change colors…)
  • CAM Jobs: CAM stands for Computer-Aided Manufacturing. It generates output data for the manufacturing tools (for exemple exporting Gerbers files which is the most used professional format).
  • Projects: this entry lists the examples and projets. When a new project is created, it is automaticaly added in the tree.

The Arduino MEGA2560 board has been designed with EAGLE. It is provided within the examples:

Arduino

Directories

Basicaly, EAGLE stores all the projects and necessary files in the same main folder and creates subfolders to differenciate each projet. In the main menu bar, select Option > Directories:

Menu_Directory

The following interface allows the user to configure directories. $EAGLEDIR represents the path to the main folder (on my installation it is located in /home/username/eagle-6.5.0/). When a new project is created, a new folder is automatically added in $EAGLEDIR/projects/ . The user can specify several folders. It is possible, for example, to have the default libraries available on a network server, and the personal projects in private local folders.

Directory

Before continuing check that the folder for libraries is configured with the following path: $EAGLEDIR\lbr.

Libraries

On the left hand side of the control panel, click on Libraries to develop the tree and select the library 74xx-eu.lbr. This library is dedicated to TTL Devices (74xx Series from Texas Instruments). Select a device, on the right side the symbol and footprint appear:

Library

New project

To create a new project, select File > New > Project :
NewProject

A new project is automatically added on the left hand side of the window under the branch Project/eagle. Enter you project name, for example FirstPCB :

ProjectName

Right click on the project and select New > Schematic.
NewSchematic

A new window is automatically open, this is the Schematic Editor:
