Problem with pin name and numbers in some components of regul library #204

Closed Calu85 closed 7 years ago

Calu85 commented 9 years ago

Using component 78L05 from regul library and footprint Housings_TO-92:TO-92_Inline_Narrow_Oval produces an error when pcbnew reads netlist. The error message is:

Error: Component 'U1' pad 'GND' not found in footprint 'Housings_TO-92:TO-92 Inline Narrow Oval
Error: Component 'U1' pad 'VI' not found in footprint 'Housings_TO-92:TO-92 Inline Narrow Oval
Error: Component 'U1' pad 'VO' not found in footprint 'Housings_TO-92:TO-92 Inline Narrow Oval

I think the problem is in the schematic component. For example, pin table of 78L05 shows both number and name fields have the same value, namely [VI, VI], [VO,VO] ,[GND,GND], instead of [1,VO],[2,GND],[3,VI]. I modified the schematic component to have number 1,2,3 in the numbers fields and it solved the problem. Is this a problem in the library? I have searched a little and I have found some people with the same problem in older versions of kicad. I could fix it and make a pull request, but first I'd prefer to be sure that this is a problem and not something I am doing wrong in pcbnew. Many thanks.

Yes, this is an issue that should be fixed. However I see the two different ways to solve this issue:

  1. We fix the pin numbers for generic symbols of these linear regulators and leave them in regul.lib library for quite backward compatibility. Of course this will not be the full compatibility, because we need to apply KiCad Lib Convention (KLC) rules. So at least pin endings might/will be not at the same positions anymore.
  2. We remove all these generic symbols, because we have many counterparts of 78L05 series regulators in this library: LM78L05ACZ, MC78L05AACP, etc., which have correct pinning, link to datasheet, housing and are correct in terms of KLC, and might be used as template symbols for others.

I'm rather for this second option, even if this smash a few schematics (We did already worse things :) ).

That is my position on this issue. Now I'm waiting for Yours, and other key librarians: Carl, Ricardo, Michał (Sorry if I skipped someone).

I'd go for deleting them as well.

The pins names issues will be fixed when https://github.com/KiCad/kicad-library/pull/223 pull request will be merged. The question about remove generic symbols still remains...

odurc commented 9 years ago

I can take advantage and remove this symbols too. They are: 7805, 78L05, 7805MS, 7905, 79L05. Any other else?

Removing them I'll have to convert some LM7*\ alias to real symbols.

@Calu85 Hi can you please consider closing this issue if its not relevant any more?

Calu85 commented 7 years ago

OK. I hadn't noticed it was still opened.

gechxx commented 7 years ago

Hi so what the resolution.Im still getting stuck on check not accepting the 7805

poeschlr commented 7 years ago

You might want to give more details here. I have no clue what you are talking about.

jkriege2 commented 7 years ago

Please also note that regul.lib received a complete workover (see https://github.com/KiCad/kicad-library/pull/948) Maybe that fixes your problems (i.e. update your libs and try to exchange your symbols for new ones ...)

Best, JAN
