A quick guide to using and personalizing Eagle configuration script files to tailor settings to your needs.

Download Open Board Viewer - Easily view EAGLE circuit board files (.brd) and quickly search for any component with the help of this lightweight and useful application. This post explains how to create a 3D CAD model from a PCB design from EAGLE. The following versions of the software are used: Eagle 6.6; Solidworks 2014 (with CircuitWorks) Export from Eagle. First, the board outline must be specified in the layer 20 (Dimension). If there is no board outline, add a close shape on layer 20 with the Wire tool. In this tutorial we'll cover every step in EAGLE PCB design: from placing parts, to routing them, to generating gerber files to send to a fab house. We'll also go over the basics of EAGLE's board editor, beginning with explaining how the layers in EAGLE match up to the layers of a PCB. From here, go to the File menu, then go Open Job.

Let's talk about Eagle Configuration Scripts: how to use them, and why using your own can make your Eagle experience more enjoyable and efficient.

Let me preface this by saying that there is more I do not know about Autodesk's EAGLE PCB Design Software than there is that I do. That said, this is just a quick explainer, and there will be plenty left unsaid about using Eagle scripts.

If you are new to Eagle or unfamiliar entirely, check out these tutorials to help you get started:

What is a Configuration Script?

Put simply, it's a file used to configure an instance of Eagle with specific settings when opened.

When an instance of an Eagle editor is opened, Eagle accesses a configuration script file (eagle.scr). The configuration script contains a series of commands written in human readable text that change the settings for any instance of an Eagle editor workspace when opened. These include: BOARD Editor, SCHEMATIC Editor, LIBRARY Editor, DEVICE Editor, PACKAGE Editor and SYMBOL Editor. By changing the set of commands within the configuration script, the user can customize the settings of any of the aforementioned Eagle editors without the tedium of having to manually change the settings every time you open up an instance of Eagle.

Perhaps the most valuable feature of a personalized configuration script is the ability to setup a hotkey assignment map and workspace that caters to how you use Eagle. Whether you are designing schematics, designing boards, designing both or just reviewing designs, you can tailor the configuration of Eagle to allow you to work more efficiently.

Eagle is distributed with a default configuration script; it sets some default layers to be used, sets the unit(s) of measure, sets the grid spacing and calls some .ulp files, plus a few more things. Check it out below:

This default Eagle configuration script by no means makes Eagle unusable, but you are stuck with some pretty basic configuration settings. We have a SparkFun Eagle Settings GitHub repository, which includes an Eagle configuration script that provides a good starting point for understanding how these scripts are used, and for personalizing your own.

If you are new to GitHub, below are a couple tutorials explaining what it is, and how it is used:

Below is a simple demo configuration script to use as an example. Let's quickly break down some of the script so that you can get started making or modifying your own!

Anatomy of a Configuration Script

The configuration script is broken into a section for each variation of an Eagle editor, and each type is denoted by an editor-specific label. These labels instruct Eagle to run only the portion of the script that is between the editor type label being opened and the next editor label. This means the user can customize unique configuration settings for each editor type, most importantly hotkeys.

Eagle Editor Script Labels

Editor Type	Editor Label
Schematic	SCH:
Board	BRD:
Library	LBR:
Device	DEV:
Symbol	SYM:
Package	PAC:

The portion of the script that lies above all labels is considered global. These instructions will run for any editor type opened, and will run before the instructions under the editor-specific label are run. Instructions under an editor label will supersede any global instructions that were run prior to the editor label.

To add a comment to your script, insert a pound symbol (#) followed by the text for your comment. Each new line of comments will require a new preceding pound symbol. A comment can live on the same line as a command, assuming it is stated after the command.

Eagle Commands

Eagle utilizes a built-in set of text commands that tell it to do anything from setting a layer's color to setting default wire widths. These commands can be used in place of any of the toolbar buttons, and the command structure and syntax is standardized within Eagle. Conviniently, the commands that can be entered into the command line field of an editor workspace are identical to those that are used to populate an Eagle configuration script.

As a side note - To utilize a command in a workspace, simply enter the command into the Eagle command line field with proper syntax and press enter. It should be said that some commands are specific to a certain type of editor, for example, a command specific to the schematic editor may return an error if entered into the command line of a board editor. This is also true of commands in a configuration script.

Lets look at a basic Eagle command used under the BRD: label in the above demo configuration script, and discuss the syntax and function. Download fifa online 4 for mac. Checkout the command:

Grid inch 0.05 on;

This command tells Eagle to configure three settings:

inch - sets the unit of measure to be used for the grid to inches
0.05 - sets the grid spacing to 0.05 units
on - sets the grid to be visible to the user

The command is 'Grid,' and the parameters are: 'inch,' '0.05' and 'on.' The semi-colon ';' tells Eagle that there are no more parameters. Remember, this command lives under the BRD: label, which dictates that this command will only be used when opening an instance of the board editor.

You can easily chain together parameters for one command by listing them separated by a space, and terminating the command by adding the semi-colon at the end. Here's another example:

DISPLAY 1 16 17 18 19;

This tells Eagle to make layers 1, 16, 17, 18 and 19 visible to the user. It's pretty intuitive. Interestingly, one could design an entire schematic with a string of text using Eagle's built-in commands.

Writing and Editing a Configuration Script

Eagle contains a built-in text editor that can be used for writing/editing SCRIPT and ULP files, but you can use any text editor that allows you to choose the file extension when saving your
