+ | ===== 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 | ||
+ | [[http://www.seul.org/cgi-bin/mailman/listinfo/geda-user]]. (The archive is not at this location anymore) | ||
+ | |||
+ | 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]]. :-) |
