[kicad-users] PCBnew : module with same pin numbers causing fatal error when filling zone

2010-02-04 Thread Stephrac74
Wow…

One more making me upset ! 

I’ve modified a LCD module in order to put the same pin number on fixing
points as the GND pin. Thus, the fixing points are connected to GND.

 

But then impossible to refill the zones on my PCB : Fatal error causing
PCBnew to close each time I try to refill after having changed the module by
the modified one…. (Memory could not be read at address xxx)

 

That sucks !

 

Does someone faced this situation ?

RE: [kicad-users] module editor bug ? Edit pad -> bug found !

2010-02-04 Thread Stephrac74
Answer to myself…. Found the bug, and bug it is ! 

 

In order to edit pads in the module editor on a selected components, the
concerned layers in PCBnew must be active.

 

in PCBnew, I had unticked the copper layer because I was working on the
component layer and  then I couldn’t edit standard pads with copper on both
side, but only smd pads on component layer ! 

 

Ticking again all the layers solved the issue.

 

Just to know that one ….

Objet : [kicad-users] module editor bug ? Edit pad

 

  

Hi group,

 

I want to edit some pads in the module editor of some components already
created.

Most of the time the right click on the pad don’t show the Edit options. If
I create a new pad, it starts again at 2 as if the editor don’t know some
pads are created.

It happens with standard and own libs….

 

It seems there is a condition that I don’t find to reproduce the ‘bug’ but
cand find out what it is at the moment.

 

Any idea ?

It should. As long as you have regenerated the netlist and reloaded it in
PCBnew and that names are in the same sheet it you are using the standard
label option. For separate sheets you have to use the global labels option
(few icons below)

Of course, that would be nice...

But also, there could a simple browser interface, with the info obtained 
in the XML helping to find a component/module and images too. I just

hi,

what i was proposing is:
having the possibility to search the repo within kicad. that's it.

if the "owner" update the component / module in the repo it will not 
affect people who used the "old" version.

about the concern of kicad being unstable because of the repo, i don't 
see why. if we agree on a protocol (for example a xml structure), then 
any modification to the website will not affect kicad.

finally, if someone is not connected to the internet, well no problem 
the feature will be disable.

Re: [kicad-users] Re: KiCAD Parts Repo

2010-02-04 Thread Andy Eskelson
The situation is even worse if you consider your older projects.
anything that changes automatically via an on line system could be a total
disaster to a project. 

While I am fairly open to an online resource where I can browse and find
parts and modules and place them in my own libraries, it is total folly
to have an such a system update anything you are using or HAVE used. It
would be all to easy to end up with a board that at one time went to
production without any problems to one that failed. It could be something
so simple such as you changing some pad settings on a module to comply
with your PCB house, and later because an update has happened, those
settings have been wiped. 

It could be argued that if you change such settings then you should
perhaps make a copy of the mod under a different name, but I don't think
too many people would do that.

The only way that anything should be updated is at the request of the
user. It is far too dangerous to have a popup saying do you want xyz
updated.

Good to see you are still stiring up the KiCad Pot(discussion).

"Parts are parts", from the ole KFC commerical.

Designing a repo or a board requires specifying parts:
part -> manufacture(MAN), manufacture part# (MFPN), this specific 
part# nails down a footprint.  This part may have multiple schematic
symbols, one symbol, IEEE demorgan or multiple sections
such as large microprocessor SOC appearing over multiple schematic
pages.  I would says a component should end up in the design
cache with a reference to a footprint and the specific symbol
used on the schematic. Specifying a MAN and a MFPN specifies
a part from a potential whole family of parts, i.e. 100Ohm or 7400
might imply one symbol, but implies many different speed, power 
and footprints. A specific MAN, MFPN enables a procurement engineer
to construct a BOM, parts equivalents, distributors, price and buy
the parts for a board. 

The repo should be organized by family(resistors, microprocessor,etc),
description, Manufacture, Manufacture part#, spec.pdf, symbol, footprint). This 
would be a value added proposition for "part 
manufactures" to encourage the use of their part and "part distributors" if 
their part number and cost is included, where the
web site could merit a membership fee from those guys.

Here is one example (from an OrCad EDIF file) of useful properties:
(property (rename PACKAGENAME "PackageName") (string "LM2717MT") (owner 
"DataXpress"))
(property (rename DEVICESINVIEW "DevicesInView") (string "1") (owner 
"DataXpress"))
(property (rename DEVICESINPACKAGE "DevicesInPackage") (string "1") (owner 
"DataXpress"))
(property (rename DEVICEDESIGNATOR "DeviceDesignator") (string "A") (owner 
"DataXpress"))
(property (rename DEVICENUMBERING "DeviceNumbering") (string "Alpha") (owner 
"DataXpress"))
(property (rename PCB_32_FOOTPRINT "PCB Footprint") (string "MTC24"))
(property (rename &_60__32_VALUE_32__62_ "< Value >") (string "LM2717MT"))
(property (rename COMPTYPE "CompType") (string "Switcher"))
(property (rename PARTNUMBER "PartNumber") (string "LM2717MT"))(property

I agree.  but management should be automated

I think the way to make it work is to think of the local storage is a cache
for an on-line library.  A user then would not explicitly import a symbol.
If he used an on-line symbol  then automatically that symbol is copied to
the local storage.  Later if the on-line symbol is changed he is asked if
the symbol should be updated.

The software would be shipped and installed with a good symbol set preloaded
in cache.

I think you are right.

1. Because nobody wants to relay to a working internet connection during 
layouting a board. Some people actually doesn't have internet and are carying 
files around with usb-sticks.  

2. Perhaps a footprint could be changed while you are working with it.


So it would be sane to storage all used footprints separate and not touch them 
without warning.

But a plugin for importing, exporting and managing symbols, footprints and

Hello Dick.

> it is a formality to ask this question. 

Sounds in a queery way pretty german, because in german, electronic devices are 
called "elektronische Bauteile". In a short and colloquial manner, they are 
called simpel "Teile", and if you translate this literally to english, you will 
get "parts". :-)

So i think, a part is a electronical device. In KiCAD represented by a symbol 
and a footprint (module) and its Name. And, of course, also of its Type and 
Value.

Very much PCB Layout Programms are using "Devices" called by a type name, as an 
example 1N4007 or BC337. If you put them in, you have a certain device in your 
mind, and the programm adds just symbol and footprint.
Of course, you can edit this name, anyway.

KiCAD is working a little bit reverse. You are thinking of a transistor as a 
type like PNP or NPN or N-MOSFET, and place the symbol to the schematic. Later 
you have to add a footprint to this transistor like TO-92 or TOP-3 or SOT23. 
You put in a value for this transistor at any point, but actually you can 
design the hole board witout it. Other programms will start with this step. :-) 
Despite there exists often  workarounds doing the same.

So i am thinking, i am much more free in KiCAD with my way of thinking and 
creating circuits with my gut instincts, working like an artist placing devices 
on a schematic like colours to a canvas. :-)

But some people will find this inconvenient, because they have mostly a 
concrete device at their mind. They are thinking of a P600M, and want to place 
a P600M, and the programm has to put the right symbol and the right footprint 
in.

I think, this cluster of type, value, symbol and footprint is called "part". At 
EAGLE, it is called a package.

Perhaps this work could done in KiCAD by a database in CVpcb, which can be 
used, but also you can coose your own way. Similar to the field "preferred 
footprint" at the schematic editor (i have not used it yet, so i am not really 
sure, wether i am right). But with a preferred footprint only, it will be 
inconvenient if you using a lot of different footprints. 

> For footprints, there is an actual plan in place to support plugin code.

Now i am asking: what is "plugin code"? Calling footprints by name of the 
device? This may be a good way, of course, but keep in mind, that perhaps there 
are more than two or three different footprints for one name. Not only 
differend cases, but think only of different ways of mounting a TO220 device, 
like "horizontally" or "vertically" or even "reverse" from the backside of the 
board.

> I don't find symbol development to be as difficult or critical as
> footprint development, so I am starting there, at footprints.

Yes, of course. The number of needed symbols is much smaller than the number of 
used footprints. And, much more, they are usually very simple. But for me, this 
is my way to start with the symbols like i start creating a board with a 
schematic.

I believe that it would be limiting. I explain: as it is an open

changed, which is not good.

This can be avoided it it is done by a plugin :)

I have been following this thread, an I have one idea (FWIW): there 
should me an "entity" recognizeable by kicad, probably exportable in XML 
format that should contain:

payload: one and only one component or module either for eeschem or pcbnew
information: name, tags, description, *images* (maybe more than one for 
3D), author, etc..

And Kicad should be able to recongnize, import and export such "entities" .

My idea is based in that this can make it possible to make a usefull 
repository of all this, possibly even in "Google apps engine" :)

Oh! and it is very important to clearly specify the Licence (something 
like MPL) right from the begining, or it may become a problem...

hi,

i think in kicad:

symbol = component
footprint = module


the kicad repo would be for:

- projects (.pro: .sch, .brd, .net)
- schematic (.sch)
- board (.brd)
- component (.lib)
- module (.mod)


what do you think about the idea of accessing the repo within kicad?

In the module (moduleditor?) use the property tool and chance the pin/pad name, 
that both pins 1 and 5 have the same name.

Pierre told me this somme weeks ago in another thread.
But because of time problems, i wasn't able to test it yet. Perhaps i 
misunderstood this.

I think, this name has to be fitting to the name of the pin in the symbol from 
the schematic. So i think, the name should be "C" like "cathode". But better 
look into your symbol.

What is a "part"?   This is not a term I find in the Kicad UI anywhere, so it 
is a formality to ask this question.  I know what a footprint is (normally 
called a module in PCBNEW), and I believe EESCHEMA uses the term "symbol".   So 
what do you understand under "part"?   Is there something that needs to be 
changed in the Kicad UI?


For footprints, there is an actual plan in place to support plugin code.  I am 
the task lead on it, and it should start in March or April, after the pending 
release is out.  This is intended for PCBNEW.  From this work, there may be 
something usable for symbols that can be carved out of it and for incorporation 
into EESCHEMA.  But my current focus and commitment is to PCBNEW's footprint 
support.


I don't find symbol development to be as difficult or critical as footprint 
development, so I am starting there, at footprints.  Once there is a way to 
globally name a footprint (and I do mean global in the purest sense), then 
perhaps symbols can be taught to reference them.

Ie a display like the SC23-11 display where both pin 1 and 5 are connected to 
the cathode. To be able to use either or both pins and/or the display itself as 
a "jumper" helps, but how do I communicate that to KiCAD?



Re: [kicad-users] what does pin shape low in mean? is that the same as active low?

2010-02-04 Thread Robert
Thanks, that's certainly a useful document.   However, I'm confused. 
It appears to be an IEEE (ie American) standard, but it does make 
reference to the IEC.   The international standard, as far as I can 
tell, is IEC60617.   I don't know if there is an ISO standard or if 
IEC60617 was produced in conjunction in some way with the ISO.   Does 
this document in fact represent IEC60617?

There has been quite a bit of discussion about libraries on the list 
recently.   IMHO it would be better if kicad libraries as a minimum 
followed an international standard; I know I'm not the only person not 
to recognise library symbol CAPAPOL, and that's just a capacitor. 
Should that standard be IEC60617 or something else?

I did try to find a copy of IEC60617, but the IEC want money for it.

Regards,

Robert.

  I was just researching this today. Since no-one else has replied, I'll 
  let you have the benefit of my inexpert opinion. I came to the 
  conclusion from my research that it is used with IEEE standard symbols, 
  but apparently it is interchangeable with the invert (round circle) 
  symbol. However, adding a symbol to a standard that means the same as 
  one that already exists in that standard seems illogical to me.

  I did try to find out what the IEC standard is, but they would only tell 
  me if I crossed their palms with gold. I'm not sure what is the point 
  of a standard that is only revealed to a select few.

  Regards,

  Robert.
