Re: GSOC 2022 | LTSpice schematic importer for KiCad

 

Hi Roberto,

Sure, will understand through the link how can I contribute effectively.

I have gone through the bugs page I guess this should be good to start with
https://gitlab.com/kicad/code/kicad/-/issues/11391

my Cmake generation is done, currently building the code. Once that is
done. will do what Thomas has suggested. This will help me to understand
the code as well.

Thanks
Chetan
