 +====== This page should include user experiences with the gEDA suite. ======
  
 +===== Paul Csanyi'​s experiences =====
 +
 +Hello!
 +
 +My name is Paul Csanyi. I am a technics teacher in an elementary school.
 +
 +I use mainly Debian GNU/Linux operating system. I have installed the gEDA suite on my system. ​
 +
 +I am a newbe to the electronics and to the gEDA tools, but the electronics is so interesting theme to me so I decide to study gEDA tools and use it for making some simple projects. With these simple projects I intend to teach my pupils to fundamentals of electronics.
 +
 +I tried first the gEDA GUI, but then I red that it is better to use gEDA from the command line, so I did so.
 +
 +I have tried several times gEDA tools to make some simple projects. Up to the present I learn how to use gschem tool very easily. ​
 +I made schematics easily. ​
 +
 +But then I need a symbol that I can't find in gschem library, so I decide to make it. I follow the tutorial
 +[[http://​wiki.geda-project.org/​geda:​tragesym_tutorial]] and ask some questions on the mailing list geda-user
 +(The list is not active anymore - check [[geda:​mailinglists|archives and current lists]]).
 +
 +Here in this Wiki I want to share some of mine experiences with the gEDA suite. I want to share some addons to the tragesym tutorial.
 +
 +If these thoughts are specific for the Debian system, like the place of the tragesym_template.gz file, then I shall write a note of this.
 +
 +I made a symbol for the 36-pin Centronics connector.
 +
 +From the "​Tragesym tutorial":​
 +
 +**Step1: Open a tragesym template file**
 +  * open xterm window: eg.: urxvt
 +  * cp /​usr/​share/​doc/​geda-doc/​wiki/​_media/​tragesym_template.gz ~/gEDA/gaf/ \\
 +__Note: This is Debian specific.__
 +  * cd gEDA/gaf/
 +  * gzip -d tragesym_template.gz
 +  * Open in OpenOffice the tragesym_template file. I get OpenOffice Calc with opened file. "Set the type, style and position column to the most common value."​ I have saved this **tragesym_template** file for the future use.
 +
 +**Step2: Download the part data sheet and find the pin list**
 +
 +**Step3: Copy the pin list into an editor and prepare it**
 +  *I have tried Midnight Commander as editor, but XEmacs is much better for this. I make Tabs between columns. From XEmacs I copy the lines into OpenOffice Calc.
 +
 +**Step4: Insert all missing data into the spreadsheet**
 +  *In OpenOffice Calc I inserted all missing data. The label of the Pin 36 is 'IN SEL' and have a negation overbar, so I write in the approppriate column: \_IN\ SEL\_ Note that here is a space between '​IN'​ and '​SEL'​. Maybe it is trivial, but if one have a space in the label this works.
 +
 +**Step5: Export the spreadsheet into a tab seperated text file**
 +  *In OpenOffice I did File / Save As / Filename: tragesym_template-for_36-pin_centronics_connector / Filetype: Structural text (CSV) (.csv) / Filter setup: on / Save / Text boundary: empty
 +
 +**Step6: execute tragesym and create the symbol**
 +  *tragesym tragesym_template-for_36-pin_centronics_connector 36-pin-centronics.sch
 +
 +**Step7: check the result with gschem and do some artwork**
 +  *"Now we have a complete symbol."​
 +  *"You can copy the symbol to your local symbol library e.g. /​usr/​local/​share/​gEDA/​sym/​local/​ and use it." \\
 +cp 36-pin_centronics.sch /​home/​username/​gEDA/​gaf/​gschem-sym/​connectors/​36-pin_centronics.sym
 +
 +This symbol can be viewed here: \\
 +[[http://​www.mediamax.com/​paul_csanyi/​Hosted/​gschem_schems/​36-pin-centronics.sym]] (dead link)
 +
 +In this symbol I put the footprint: "​SUBD_FEMALE_LAY 25" but this is not the approppriate footprint for the 36-pin Centronics connector. I tried to find footprint for the 36-pin Centronics connector here:
 +[[http://​www.gedasymbols.org/​]],​ but with no success.
 +
 +I think I gone to make one 36-pin Centronics footprint soon, using "PCB Footprint Guide" here:\\
 +[[http://​wiki.geda-project.org/​geda:​pcb_footprints]]. :-)
