Re: [kicad-users] Re: New to KiCad
Hi, The only thing to watch out for is that when you've defined the Vcc pin to be a power pin, it needs to be driven from a power source. On this simple design, the power is coming in from the connector, which of course should have all pins as passive. You therefore need to add a pwr_flag from the power ports list to tell Kicad that it's ok. Kicad is a very useful software, and I tried to do a circuit with 386EX in it. But I ran into problems where the pins were defined as bidirectional or had multiple uses. How do I represent such pins on Kicad ? Yukku

From my investigation it look like a poor OpenGL implementation since windows Vista. Using a PC with or without graphique card has no performance impact. So my conclusion is that there is no OpenGL hardware support since windows Vista. Maybe Microsoft wants favor directX.

[kicad-users] Footprint for a Relay ?
Hi, I am using the Relay RELAY_2RT from the EEschema device library. I have a couple of question about it - 1. Why does it not use contiguous pin numbers instead using pins 1,3,5 8,9 and 12,14,16 ?

Hi, Thank you for the answer. That brings me to the question as to what to do if I do not have a data sheet for the part.

It all depend what actual device the part was based on, but essentially it is as you say. Relay bases have a long history. Find the data sheet for the actual relay you are going to use and pick the footprint from that. My suspicion is that the device in the library is a DIL16 part so you would need a 16 pin DIL 0.3 footprint for the library device if you are using the same part that the library is created for.

Many relays have a standard numbering system, especially if they are intended to be plugged into some form of holder. there are some variations, but generally they are two digit such as 11, 12, 13, 21, 22, 23 and so on, the coils are normally A1 and A2. I have also seen some bases with a letter and a number as well. The numbers refer to the poles and contacts, so 11 is pole 1 contact 1, 12 is pole 1 contact 2, 21 is pole 2 contact 1 and so on. I can't remember offhand which is the normally closed/open and common connections, I usually end up buzzing it out to be sure :-) Miniature PCB mount relays tend to be a little more variable. As for footprint, well you use the footprint that matches the relay... (I cannot see one in the standard lib) I drew up a simple footprint the last time I used a relay. I've used this SPST 12V 10A directly soldered into the PCB http://www.rapidonl ine.com/searchre sults.aspx? style=0kw= 60-4600 and the 60-4110 Double pole socket http://www.rapidonline.com/Electronic-Components/Relays-Solenoids/PCB-Relays/Miniature-relay-sockets/28667/kw/60-4110 I have simple footprints for both, if they are of any use you are welcome to a copy.

It seems to appear on vista and Win7 platforms –but I never used kicad under windows XP). You have 3 ways to circumvent it First method : totally suppress both grounding zones, and recreate an upper and a lower grounding zone but far smaller than the size of your pcb. Fill these zones, and then use the “summit drag and drop” function to resize the grounding zone to the right area and dimensions. Second method : kill your pcb perimeter (the yellow contour) and define a new one with slightly different dimensions (you’ll have to readjust these drawing later) and redraw your new filling zone with the exact size you initially intend. Third one : use the second method an suppress all the grounding vias at the same time. Don’t ask me why, but I had this frustrating bug several time and couldn’t find a precise answer on this mailing list. It could look a little bit “shamanic” but it works The first method don’t seems to work every time.

You can access them either via the help menu option in each program or directly (they are .pdf files, they live in /usr/local/kicad/ doc/help along with some other help related files. If using windows they live under kicad/doc/help (wherever you installed kicad to) The basic process for zones is fairly easy. Click on the zone tool A window pops up, select the net that you want the zone to attach to, or no net for isolated zones click on OK Draw the outline of the zone End the tool then if the zone is not filled, right click and select fill/refill all zones.
