Library Framework

We use this framework of library folders:

• Eagle
• Projects
• Ex

Schematic Draft

Draw schematic draft:

• Find as much components (with correct footprint) as you can.
• Which Oscillator Output Signal is Best for Your Application?

Value and Partno

Based on partlist and BOM excel sheet:

• use: D:\EAGLE-Tools\bom-ex\value-partno\write-sheets.js.

BOM

Two websites: https://octopart.com/, DigiKey

Firefox Browser Extension

Please refer to:

• Your first extension
• To install: Open about:debugging in Firefox, click Load Temporary Add-on to select your extension.

RunWith

Please refer to:

• Runs the selected string as a command line parameter of a local program via right-click or Tools menu.
• This method is deprecated: as it is not compatible with new version Firefox.

Buttonize Digi-Key Part Number

We copy/modify example of "native-messaging":

• Example extensions
• D:\EAGLE-Tools\bom-ex\runwith-native-messaging\add-on-new: manifest.json
• --- background.js: connect to ping_pong app
• --- find-dknumber.js: buttonize Digi-Key part number.
• Windows Registry for ping_pong app:
• --- App Manifest Location
• --- D:\EAGLE-Tools\bom-ex\runwith-native-messaging: ping-pong.reg
• D:\EAGLE-Tools\bom-ex\runwith-native-messaging\app: ping_pong.json
• --- which calls: ping_pong_win.bat
• --- which calls: D:\EAGLE-Tools\bom-ex\Grab-Bag-master\Bom-ex\new-addDKPartToBom-ex.py
• --- which adds to: D:\EAGLE-Tools\bom-ex\*-db.txt

Note: to jump to a given line number, you can directly use: $text->setCurrentLineNumber($x);.

Finalize Schematic

Finalize schematic:

• Collect all components to D:\EAGLE-Tools\bom-ex\*-db.txt
• Replace components with correct attributes: value, PARTNO (manufacturer)
• PARTNO (manufacturer) is the keyword for matching items in database
• Check with D:\EAGLE-Tools\bom-ex\mybom-ex.ulp: click Load DB

Finishing Board

Please refer to:

• How to change font size throughout brd
• How do I change all fonts to vector on the same PCB at once?

To smash all the parts, try:

• display none tOrigin bOrigin;
• group all;
• smash (>0 0);
• display last;

To change the font and ratio, try:

• display none tNames bNames;
• group all;
• change font vector (>0 0);
• change size 40mil (C>0 0);
• change ratio 15 (>0 0);
• display last;

View in Gerbv

Please refer to:

• drill layer wrong size
• Right click main.drd layer, and select Edit file format dialog.
• Turn off auto detect and set 5 digit.

Text API

One of the main entity:

Important: lines is an array of string stripped from their line break character.

If you need to manipulate a simple string you can use Text::fromString:

Important: please note that upon creation, the current line number is initialized to the first line: 0 (array indexed).

Side note on Line Breaks

A StringUtil::detectLineBreak method is used to find the line break, this is done using the following rules:

• \r\n for windows
• \n for any other operating system
• PHP_EOL if no line ending has been found

File API

The other main entity:
