Where are parts stored locally on Mac?

Hello,

I’m sketching out a simple project that I’ve already assembled so I have it documented. Arduino Nano, NEMA 17 stepper, A4988, and 1.44 SPI TFT screen.

Now I’m trying to add a 1.44 SPI TFT screen to my parts library. I found 2 examples - however, both are incorrect for my pin configuration. Here is the version of the screen I have: https://www.instructables.com/Using-TFT-144-With-Arduino-Nano/

After I loaded the 2 examples I found, realizing they’re not a match, I later tried to delete them. But–after struggling to no end traversing the curve of making a new part (or modifying one of the existing ones), I decided to go back to square one, and work with what’s there.

But alas! It’s not there - AND I cannot re-import it (It does nothing).

I only have the 2 extra parts on there, so I don’t mind losing them, but how do i reset the library on Mac?

(and where do I ask my next question: what is the best way to widen the PCB to make room, then add silkscreen labels to 8 of the pins and delete 3 of them on this: 1.44in SPI TFT Color DIsplay 128x128 created OR any idea where to get an fzpz of the actual screen as in the link above?)

Thanks!

I’m not entirely clear on what you are asking here, but assuming you want to delete all your custom parts these directions will do that:

There are two user directories (with your parts and the parts database) which don’t get touched during an install (to not affect your sketches during upgrades). On Windows they are in

c:\users\username\AppData\Fritzing\roaming\Fritzing (which is a hidden directory so you need to enable hidden directories in explorer) and

c:\Users\username\My Documents\Fritzing (where username is your windows id)

If you don’t have any parts or sketches you want to keep you can just delete those two directories and Fritzing will recreate them, or you can move them aside by renaming them if you want to keep something in them.

linux

~/Documents/Fritzing/parts
~/.config/Fritzing

Mac

/Users/username/Documents/Fritzing/parts
~/.config/Fritzing

I think you are saying that you attempted to delete the parts but failed and now can’t reload them. I assume that when you say you can’t reload them you mean that you get an error message of the form

capture

which indicates that the part is still present in Fritzing. You should be able to find it by doing this:

You should then be able to delete the part and then exit Fritzing (which is required to actually remove the part!)

At the first prompt answer yes to modify the parts bin. Then answer discard (because you don’t want to save the .fzz file)

then answer save to the next prompt (I suspect you answered discard either here or at the first prompt and then the opposite here)

this then deletes the part and will let you reload it. If you answer save to the first prompt but discard here it will save the part but delete it from the mine parts bin which I think is likely what happened. Now I will have a look at the display you want and see what I can do.

edit:

There is a part which should do what you want available here:

Amazing!

I was able to trash the directories and reload the parts. The app would not load the parts again after i tried deleting, and re-importing did nothing. This fixed it. thank you!

And WOW - that’s the part I spent most of today looking for and trying to make/modify. I can’t thank you enough. How did you find that? Did you make it for the previous thread? Nothing I searched for returned that link.

Thank you!

There isn’t any reference in that thread to tft displays Ithe OP was using an antenna as the display) so google doesn’t appear to pick it up. I had to find it in my parts archive (because I remembered making it) then search the forum for the .fzpz file to find the original post. Hopefully google will now find it if we search for 1.44in tft display.

Thank you for taking the time to help. I’ve completed 90% of my sketch already. Some days are just like that–happy to have made the progress.
