Part Editor confusion

I am trying to create an INA125 DIP 8pic IC. For the life of me I cannot figure out how to rename to IC in the part editor. After I have made my label changes in the Metadata and under ‘File’ I have ‘Saved as new part’. In my Parts bin I can see my newly created part which is labeled correctly. When I then import my new IC from ‘My parts’ bin the IC is still labeled ‘IC’, not my number. How do I relabel my newly created IC???

When you first create the part, in inspector (lower right window) setting Chip label from IC to your part number will do the trick. In parts editor the Properties field Chip label (the first one) is the same. Change IC in there to the part number you want and it will propagate in to the svgs and thus your part.

Thanks for the help Vanepp. I’m still not able to change my IC label, here is what I have going on. I think I have followed your instructions but please have a look at my screen grabs. I know i’m overlooking something very simple but…


I’ve just noticed that in “Breadboard View” that my IC is labeled correctly. Really confused…

Yes, breadboard view is overwritten by whatever is in part label. The same should be true of schematic I think. If you export your part to an fpfz by right clicking on it in the mine parts bin and clicking export part and post the fpfz file I’ll have a look at it and see whats wrong (at least probably :slight_smile: ).

OK thanks. Im not in front of my computer right now but Ill post when I can.

I have another question not related to this topic. I will start another thread so if your board please have a look.

I’m often frustrated but rarely bored :slight_smile: Also the though struck that schematic may be using the part number property in parts editor rather than the label property. If there isn’t a part number property just add one by typing

part number in the “a label” field and your part number in the data field. At worst you have to modify the schematic svg file with Inkscape or the like.

After much delay I’m back with the file you offered to look at. Thanks.

OK, I’m unclear that this is correct, because google says an INA125 is a 16 pin instrumentation op amp not a mircrocontroller, but here is a part with the part numbers corrected. I unzipped the fzpz with 7zip (the instructions for doing that are in my parts creation howto in beginners), then used Inkscape to edit the breadboard svg to actually add the INA125 label (it was being defaulted from Fritzing rather than being in the svg) and moved it so it was better centered in the IC. Then I used Inkscape on the schematic svg and modified label in there to INA125 as well and saved them both. I copied breadboard svg in to icon.svg (so the new label will be on the icon as well) and then edited the icon and breadboard svgs to remove the px that Inkscape helpfully adds (which breaks Fritzing) and rezipped the part. If you are actually trying to make the op amp rather than a micro controller you would be better off to start with a 16 pin generic IC as your base and would need to use Inkscape or another svg editor to create the schematic (if you want more than a box with the pin names at least as the schematic). It looks like the parts editor doesn’t in fact propagate the labels to the svgs which I thought it did (but I rarely use parts editor other than to create the description anyway). .

Well just crap. I’m really sorry to put you through all of that but I’m using a INA126. An 8 pin amp. I am using an Arduino and a load cell in project and the 126 is my amp for the load cell. Thanks so much for helping me on this and fixing my part in Inkscape. It’s frustrating being a newbie sometimes.

I installed Inkscape into my computer and started to mess around with it but didn’t accomplish anything constructive so far. Just a matter of reading some tutorials though.

Not a problem, I’ve been in parts creation hell for months :slight_smile: and am just paying forward all the help I’ve gotten. Even better than the generic IC would be to start with one of the op amp ICs which have the schematic for the op amp already done for you then you just need to either edit the pins around rather than try and draw the entire schematic from scratch.

I was one digit off. ‘I always mess up some mundane detail’. Classic Office Space movie quote.

I agree that is a better idea using an existing amp.

Thanks again for all you help and work.

No problem, feel free to ask for help going forward, parts creation is poorly documented and complex but there is a fair amount of experience around.
