  22 Hello!
  23 </p>
  24
  25 <p>
  26 My name is Paul Csanyi. I am a technics teacher in an elementary school.
  27 </p>
  28
  29 <p>
  30 I use mainly Debian GNU/Linux operating system. I have installed the gEDA suite on my system.
  31 </p>
  32
  33 <p>
  34 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.
  35 </p>
  36
  37 <p>
  38 I tried first the gEDA <abbr title="Graphical User Interface">GUI</abbr>, but then I red that it is better to use gEDA from the command line, so I did so.
  39 </p>
  40
  41 <p>
  42 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.
  43 I made schematics easily.
  44 </p>
  45
  46 <p>
  47 But then I need a symbol that I can&#039;t find in gschem library, so I decide to make it. I follow the tutorial
  48 <a href="http://wiki.geda-project.org/geda:tragesym_tutorial" class="urlextern" title="http://wiki.geda-project.org/geda:tragesym_tutorial" rel="nofollow">http://wiki.geda-project.org/geda:tragesym_tutorial</a> and ask some questions on the mailing list geda-user
  49 (The list is not active anymore - check <a href="geda-mailinglists.html" class="wikilink1" title="geda-mailinglists.html">archives and current lists</a>).
  50 </p>
  51
  52 <p>
  53 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.
  54 </p>
  55
  56 <p>
  57 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.
  58 </p>
  59
  60 <p>
  61 I made a symbol for the 36-pin Centronics connector.
  62 </p>
  63
  64 <p>
  65 From the “Tragesym tutorial”:
  66 </p>
  67
  68 <p>
  69 <strong>Step1: Open a tragesym template file</strong>
  70 </p>
  71 <ul>
  72 <li class="level1"><div class="li"> open xterm window: eg.: urxvt</div>
  73 </li>
  74 <li class="level1"><div class="li"> cp /usr/share/doc/geda-doc/wiki/_media/tragesym_template.gz ~/gEDA/gaf/ <br/>
  75 </div>
  76 </li>
  77 </ul>
  78
  79 <p>
  80 <em class="u">Note: This is Debian specific.</em>
  81 </p>
  82 <ul>
  83 <li class="level1"><div class="li"> cd gEDA/gaf/</div>
  84 </li>
  85 <li class="level1"><div class="li"> gzip -d tragesym_template.gz</div>
  86 </li>
  87 <li class="level1"><div class="li"> 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 <strong>tragesym_template</strong> file for the future use.</div>
  88 </li>
  89 </ul>
  90
  91 <p>
  92 <strong>Step2: Download the part data sheet and find the pin list</strong>
  93 </p>
  94
  95 <p>
  96 <strong>Step3: Copy the pin list into an editor and prepare it</strong>
  97 </p>
  98 <ul>
  99 <li class="level1"><div class="li">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.</div>
 100 </li>
 101 </ul>
 102
 103 <p>
 104 <strong>Step4: Insert all missing data into the spreadsheet</strong>
 105 </p>
 106 <ul>
 107 <li class="level1"><div class="li">In OpenOffice Calc I inserted all missing data. The label of the Pin 36 is &#039;IN SEL&#039; and have a negation overbar, so I write in the approppriate column: \_IN\ SEL\_ Note that here is a space between &#039;IN&#039; and &#039;SEL&#039;. Maybe it is trivial, but if one have a space in the label this works.</div>
 108 </li>
 109 </ul>
 110
 111 <p>
 112 <strong>Step5: Export the spreadsheet into a tab seperated text file</strong>
 113 </p>
 114 <ul>
 115 <li class="level1"><div class="li">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</div>
 116 </li>
 117 </ul>
 118
 119 <p>
 120 <strong>Step6: execute tragesym and create the symbol</strong>
 121 </p>
 122 <ul>
 123 <li class="level1"><div class="li">tragesym tragesym_template-for_36-pin_centronics_connector 36-pin-centronics.sch</div>
 124 </li>
 125 </ul>
 126
 127 <p>
 128 <strong>Step7: check the result with gschem and do some artwork</strong>
 129 </p>
 130 <ul>
 131 <li class="level1"><div class="li">“Now we have a complete symbol.”</div>
 132 </li>
 133 <li class="level1"><div class="li">“You can copy the symbol to your local symbol library e.g. /usr/local/share/gEDA/sym/local/ and use it.” <br/>
 134 </div>
 135 </li>
 136 </ul>
 137
 138 <p>
 139 cp 36-pin_centronics.sch /home/username/gEDA/gaf/gschem-sym/connectors/36-pin_centronics.sym
 140 </p>
 141
 142 <p>
 143 This symbol can be viewed here: <br/>
 144
 145 <a href="http://www.mediamax.com/paul_csanyi/Hosted/gschem_schems/36-pin-centronics.sym" class="urlextern" title="http://www.mediamax.com/paul_csanyi/Hosted/gschem_schems/36-pin-centronics.sym" rel="nofollow">http://www.mediamax.com/paul_csanyi/Hosted/gschem_schems/36-pin-centronics.sym</a> (dead link)
 146 </p>
 147
 148 <p>
 149 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:
 150 <a href="http://www.gedasymbols.org/" class="urlextern" title="http://www.gedasymbols.org/" rel="nofollow">http://www.gedasymbols.org/</a>, but with no success.
 151 </p>
 152
 153 <p>
 154 I think I gone to make one 36-pin Centronics footprint soon, using “PCB Footprint Guide” here:<br/>
