2010-05-20 Thread yukku yukkoooooo
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 ?

It seems there is some performance issue since windows vista. I run kicad on 
ubuntu via VirtualBox. By this way it's 10 times faster than directly on 
Windows 7. I did not found any workaround for the moment.

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 ?

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.

Datasheet time.

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

Today when I

I get a component selection menu
Then if I click on List all I go to the Select lib menu
Then if I Select a library I go to the Select Component menu.
But if I do not find my part in that library there is no back to Select Lib 
button. 
I have to click cancel and start all over again from the beginning.
It would be convenient if I hit the back button and go on to choose some other 
lib in the list of libs

It would useful for component browsers

Hi Yukku
Don’t worry… you’re not alone :- ) 
This “bug” (I will call it a bug as it seems
difficult to qualify it as a “feature”) is a very strange one. 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.

The tutorial is very old and gives a basic overview. Each of the
component parts of Kicad has it's own help system, section 9 of the
pcbnew help file deals with zones. It is worth reading through both the
eeschema and pcmnew help files as there is a LOT of additional info in
them.

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.

That's it, job done.

Remember that the relative co-ord display is very useful to ensure that
things align correctly, space bar will zero it.

 You are prob. falling into the very common trap of not telling the system
 that there is power on a net. This gets confusing because sometimes you
 don't have to do this.
 
 The VDD and VSS pins of the chip are both defined as power IN types. You
 can check this by using the part editor.
 
 For DRC to would correctly it much see a power OUT net attached to these
 pins.
 
 If you have some form of regulator chip on the board, the output of the
 regulator is normally defined as a power out type, so that takes care of
 the VDD voltage.
 
 However the GND/VSS connection is NOT defined as a power OUT.
 
 Next take the situation where you don't have an on board regulator, in
 this case neither the VSS nor VDD is defined as having a power OUT
 available.
 
 To overcome this is easy enough, in the powerport symbols, select a
 power flag, and attach this to the GND of you power net. The power flag
 simply tells the system that there is power applied to that net. You can
 also add a power flag to the VDD line if you are using external power.
 
 All you may then need to do is add a VSS power port to the circuit and
 attach that to the GND net, then everything should connect and DRC run
 without errors.
 
 Just remember that you almost always need to add a power flag to the GND
 networks, but sometimes not to the +ive power nets.

 this case neither the VSS nor VDD is defined as having a power OUT
 available.
 
 To overcome this is easy enough, in the powerport symbols, select a
 power flag, and attach this to the GND of you power net. The power flag
 simply tells the system that there is power applied to that net. You can
 also add a power flag to the VDD line if you are using external power.
 
 All you may then need to do is add a VSS power port to the circuit and
 attach that to the GND net, then everything should connect and DRC run
 without errors.
 
 Just remember that you almost always need to add a power flag to the GND
 networks, but sometimes not to the +ive power nets.

No, it appears the tutorial is for an older version of Kicad and the new Kicad 
GUI is somewhat different (probably better) . I guess the tutorial has not got 
updated

Does the tutorial include the power flag?  Sorry - I just use it and haven't 
done the tutorial.

You are prob. falling into the very common trap of not telling the system
that there is power on a net. This gets confusing because sometimes you
don't have to do this.

The VDD and VSS pins of the chip are both defined as power IN types. You
can check this by using the part editor.

For DRC to would correctly it much see a power OUT net attached to these
pins.

If you have some form of regulator chip on the board, the output of the
regulator is normally defined as a power out type, so that takes care of
the VDD voltage.

However the GND/VSS connection is NOT defined as a power OUT.

Next take the situation where you don't have an on board regulator, in
this case neither the VSS nor VDD is defined as having a power OUT
available.

To overcome this is easy enough, in the powerport symbols, select a
power flag, and attach this to the GND of you power net. The power flag
simply tells the system that there is power applied to that net. You can
also add a power flag to the VDD line if you are using external power.

All you may then need to do is add a VSS power port to the circuit and
attach that to the GND net, then everything should connect and DRC run
without errors.

Just remember that you almost always need to add a power flag to the GND
networks, but sometimes not to the +ive power nets.
