added Texas_S-PVQFN-N16_EP2.1x2.1mm footprint

[nivekg]

Hey Guys,

I finally created the Texas_S-PVQFN-N16_EP2.1x2.1mm and Texas_S-PVQFN-N16_EP2.1x2.1mm_ThermalVias footprints for the INA3221 symbol (KiCad/kicad-symbols#1343). Not sure if it conforms to the rules, I kept getting python errors when running check_kicad_mod.py

Thanks for creating a pull request to contribute to the KiCad libraries! To speed up integration of your PR, please check the following items:

• Provide a URL to a datasheet for the footprint(s) you are contributing
• An example screenshot image is very helpful
• If there are matching symbol or 3D model pull requests, provide link(s) as appropriate
• Check the output of the Travis automated check scripts - fix any errors as required
• Give a reason behind any intentional library convention rule violation.

We have recently discovered that the most unique identifier of the footprint is the trhee letter code. The footprint should be named Texas_RGV.

Thanks

[nivekg]

Cool, will do. Just to understand this, the files should be renamed to Texas_RGV.kicad_mod and Texas_RGV_ThermalVias.kicad_mod

[antoniovazquezblanco]

Exctly! Thanks!

[nivekg]

Done : )

footprints for standardized packages like these really should be generated via the script found here: https://github.com/pointhi/kicad-footprint-generator/tree/master/scripts/Packages/Package_NoLead__DFN_QFN_LGA_SON

Edit: oh and the footprint name must still contain the pin count. So i suggest to include the full name given to it by TI not just the 3 letters.

[nivekg]

Oops, I forgot to say the footprint was generated with that script. I'll change the name back.

[evanshultz]

The footprint does need the three-letter (or sometimes less) designation in it. So Texas_RGV_S-PVQFN-N16_EP2.1x2.1mm may be best. I believe that's what we settled on for other footprints.

[evanshultz]

And the Python errors are sadly normal. The footprint is built well but the check script isn't smart enough for the way the footprints are built by the script.

[poeschlr]

please link to the script pull request as the review will happen on it.

Hey Guys,

I renamed the footprint to Texas_RGV_S-PVQFN-N16_EP2.1x2.1mm footprint and made a PR for the footprint generator which is pointhi/kicad-footprint-generator#382

Comments left in script PR.

[evanshultz]

Please generate a new footprint to take into account the script changes. Thank you.

[nivekg]

added the updated footprint

[evanshultz]

Great. Thank you!
