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 Csányi http://www.freewebs.com/csanyi-pal/ _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
