Well…I just found that my pins were somehow set to “invisible”. This seems strange because I think I have used the symbol before. But anyway that was easy to fix…fingers crossed hoping that the below is resolved.
Also I get "This file was created by an older version of KiCad. It will be converted to the new format when saved. " But it was created with 5.99 from January.Bobs_Power_Switching_ICs.kicad_sym (31.6 KB)
I have attached the project folder. EDIT: I have also now uploaded my symbol library folder.
I take this to mean that the new file formats are not backwards compatible to older 5.99 builds… I am not sure that it matters to me, but if there is such backwards incompatibility, does it apply to pcb only or schematic also?
Thanks, paulvdh. With fingers crossed, I will say that for my purposes, forward compatibility ought to be adequate. Sometimes we need to let bygones be bygones. I did like the particular build that I was using.
