====== KiCad 2014 ======
29.9.2014

===== New Library Management =====
On my Kubuntu 14.04 I have installed KiCad with the shell-script, exactly the build #5054. \\
Kicad supports now footprints from EAGLE-Libraries. 
For simplicity I'm using the libraries from Walter Lain: http://smisioto.no-ip.org/elettronica/kicad/kicad-en.htm\\
I downloaded it with
  git clone git://smisioto.eu/kicad_libs.git
and coppied them to 
  /home/karl/Karl/Elektronik/KiCad/walter_lain
. \\
To use this modules, I replaced the file named **fp-lib-table** in the home directory with the fp-lib-table file from Walter Lain. 
Further more the environment variable KISYSMOD has to be set. This I did by adding to the file
  /etc/profile.d/kicad.sh
the line
  export KISYSMOD=/home/karl/Karl/Elektronik/KiCad/walter_lain/kicad_libs/modules
. Don't forget to logout and log back in agian, before the variable can be used. 
  

===== New Features on manual PCB Routing =====
Some guys from CERN implemented some really fancy features:
  * Highlight collisions: Shows traces in a different collor with violate design-rules with the new trace
  * Shove: move other traces, which are in the way, when routing a new trace
  * Walk around: find a possible way through the PCB without violating design-rules

Have a look at this tutorial video (10 minutes of length):\\
https://www.youtube.com/watch?v=CCG4daPvuVI

They have their own wiki-page here:
http://www.ohwr.org/projects/cern-kicad/wiki/Wiki

===== Usage of New Features =====
==== When default tool is active (cursor-symbol): ====
  * CTRL + Click on pad --> highlight the net\\deselection needs also the CTRL-modifier
  * SHIFT + Click on module --> add module to group-selection\\deselection with a click on the background

===== Bugtracking and Development =====
  * Bugtracking on launchpad: https://bugs.launchpad.net/kicad
  * Demonstration of SketchUp input methods for drawing footprints. Perhaps this could someone implement in KiCad. I sent this video to the KiCad-development-team in CERN. \\ https://www.youtube.com/watch?v=ABFolmLW9uU

====== KiCad 2015 ======

===== Updated to Revision #5373 =====
16.1.2015

After some retries, this version copmpiled without getting stuck in the middle of the whole process, which needs really some amount of time (felt like more then 1h, i didn't stop the time). 

Option:
  OPTS="$OPTS -DKICAD_USE_WEBKIT=OFF"

==== use wxWidgets 3.0.2 ====
In version 3.0.0 are many bugs. e.g.
  * hotkeys neded double press
  * wrong focus of mouse wheel

Therefore I installed version 3.0.2, as described on the website of wxWidgets:
http://codelite.org/LiteEditor/WxWidgets30Binaries#toc2

<code>
sudo apt-add-repository 'deb http://repos.codelite.org/wx3.0.2/ubuntu/ trusty universe'
sudo apt-get update
apt-get install libwxbase3.0-0-unofficial libwxbase3.0-dev libwxgtk3.0-0-unofficial libwxgtk3.0-dev wx3.0-headers wx-common libwxbase3.0-dbg libwxgtk3.0-dbg
kicad-install.sh --remove-sources
kicad-install.sh --install-or-update
</code>
The recompile needed 1 hour and 20 minutes, including downloading with an 5Mbit DSL line. 

===== BOM export =====
For me there are 2 ways to get a simple CSV file out of a KiCad project:

==== My own conversion tool on github ====
It exports all the data from the netlist-file (*.net)\\
https://github.com/KarlZeilhofer/kicad2csvbom


==== Using pcbnew for exporting BOM ====
26.2.2015\\
It seems, that this feature has been moved to pcbnew (File -> Fabrication Outputs -> BOM File). 
This feature exports a very similar format to that of my tool with the --compressed flag. 

===== KiCad Library Convention =====
If you consider to improve the standard KiCad library with symbols, footprints or 3D models, please be sure to implement the rules in this document:\\
https://github.com/KiCad/kicad-library/blob/master/KiCad_Library_Convention.txt

There are many parts in the library, which do not implement this rules, but every new component has to fulfill these!

===== KiCad Sheet Rearranger =====
7.3.2015
{{ ::kicad-sra-screenshot-20150307.png?direct&500|}}

Today I've written a simple tool for doing a rearrangement of multiple subsheets in an hierarchical schematic project. Since this feature isn't available in eeschema, this is now possible with this external tool written in with Qt. 

It is published on [[https://github.com/KarlZeilhofer/KiCadSheetRearranger|GitHub]]

===== Update Existing Footprints =====
If you have places a footprint many times on a board, and then you want to change the footprint and update all instances in Kicad, you need a bit of workaround, sinc a dedicated command is not available. 

  - Update the footprint in your library and save it. 
  - Go back to your board, and press E over one of the instances to be changed. 
  - Click "Change Footprint(s)"
  - Select "Change same footprint"
  - Hit OK

====== KiCad 2016 ======
with the ppa set up, we have to install
  sudo apt get install kicad
and (!!!)
  sudo apt-get install kicad-library

====== Benutzerdefinierte Felder im Schaltplan ======
2016-12-09, KiCad Version 4.0.2

**Wie werden benutzerdefinierte Felder von Components (Schaltplan-Symbole) verwendet, vererbt und aktualisiert?
**

==== Globale Vorlage ====
EESchema -> Preferences -> Schematic Editor Options -> Tab: Default Fields
diese Einstellung ist **global**, und gilt auch für neue Projekte \\
siehe ~/.config/kicad/eeschema
  FieldNames=(templatefields (field (name InternalName)(value Value)))

==== Vorlage in der Bibliothek ====
Dieses Feld wird auch in einem neu erstellten Component (Symbol) angehängt, 
aber nur wenn man den Dialog für "Field Properties" aufgemacht hat. Zu diesem Dialog kommt man über das große T, 
in der obigen Leiste im "Part Library Editor"

==== Component ====
Ändert man die Einstellungen in den "Schematic Editor Options"
so werden evt. neue Template-Fields in die bereits platzierten Components kopiert, 
aber erst sobald man das jeweilige Component editiert (Tastenkürzel E). 
(ähnlich zum "Part Library Editor")


===== Abgeleitete Regeln =====

Es gibt 3 Orte, wo benutzerdefinierte Felder samt Wert definiert sein können:
  - EESchema, global (Schematic Editor Options, ~/.config/kicad/eeschema)
  - in einem Component in einer Bibliothek (.lib-Datein)
  - in einem im Schaltplan platziertem Component (in der .sch-Datei)

==== Wann wird kopiert? ====
Ein Feld, bestehend aus Feld-Name und Feld-Wert, wird in der Hierarchie von oben nach unten immer nur kopiert, 
nie referenziert, und zwar:

  a) von 1) nach 2), nur wenn die Felder Editiert werden ("fettes T", Dialog öffnen reicht)
  b) von 2) nach 3), immer beim einfügen eines Components in den Schaltplan. 
  c) von 1) nach 3), nur wenn der "Component Properties" Dialog geöffnet wird. 

Ist das Feld in (3) schon angeführt, so wird es von (1) oder (2) nicht mehr überschrieben. 
Als Konsequenz ergibt sich dadurch, dass aktualisierte Feld-Werte in einer Bibliothek (2) 
nicht in einem Schaltplan (3) aktualisiert werden.
