Hello -- Congratulations on your first electronics project! I suppose it can seem kind of confusing when you start your first design, but once you've been through it a couple of times, it's really very easy.
Since you have so many questions, I suggest that you take a look at the tutorials available from this link: http://www.geda.seul.org/wiki/geda:gschem_ug#introduction In particular, the stuff written by Bill Wilson provides an excellent introduction to design using gEDA, and will answer some of your questions. Also, the Cambridge University tutorial is very good. It was written by a student who was also an electronics beginner, so he may understand your questions, and will answer them in a way you like. You may also find useful information by looking around our wiki, which you can access via the above link. Have fun with your new design! Stuart On Tue, 26 Dec 2006, csanyipal wrote:
Hello! I'm newbe in electronics and with gEDA so please help me with few advices! I try to make a PCB board for a PC interface for educational purpose. Some peaple help me from Terminal Forum: http://forum.terminal.hu/viewtopic.php?t=32764&postdays=0&postorder=asc&start=0 to design such PC interface. Then from image that give to me this boys I make a schematic "PC_interf_Oktatashoz.sch" that can download from here: http://www.mediamax.com/paul_csanyi/Hosted/gschem_schems This should to be an interface that can be to connect with an Centronics interface to LPT port of PC box. The PC interface should to get +5V from USB port. Through CONN3 should to connect relies and electromotors to control them from PC box - from applications written in Visual Basic or Pascal. I give fottprints attributes for CONN1, CONN2 & CONN3. Are these footprints right? I don't know what footprints to add for the rest of the elements. I run gsch2pcb PC_interf_Oktatashoz.sch and get WARNINGs for resistors, capacitors, LEDs & optocaplers. I have a questions for this List. What is the right way to do this work: to make a PCB for this interface? Should I buy first the electronic elements and then add footprints to the elements in schematic? I know for these address: http://www.gedasymbols.org/ http://luciani.org/geda/pcb/pcb-footprint-list.html but still I don't know which footprints to add to the elements in the schem. How to make a connection to USB port: that is, for what to sold the USB cable on this PC interface? I appreciate any advices! -- Regards, Paul Cs?nyi http://www.freewebs.com/csanyi-pal/ _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
