This has been buggin me for a while. When making a custom part in eagle how do you make 2 or more pins with the same name? IE I have a part with 5 GND pins. Instead of doing GND1 GND2 etc. I would like to just name them all GND.
From the Eagle 5.2 help file:
Pins with the same Name
If it is required to define several pins in a component with the same name, the following procedure can be used:
For example, suppose that three pins are required for GND. The pins are allocated the names GND@1, GND@2 and GND@3 during the symbol definition. Then only the characters before the “@” sign appear in the schematic.
It is not possible to add or delete pins in symbols which are already used by a device because this would change the pin/pad allocation defined with the CONNECT command.
Thankyou much! The help dosent seem to work in vista :-/
Oh! im using eagle 4.16r2 :-/
no wonder it wasn’t working.
The 4.16r2 help file says the same thing from what I can see, are you saying the help file doesn’t work, or the pin naming doesn’t work?
you cant open the help in vista, but thats expected.
Ive tried using @ and $ but the pin names still show up as VCC$1, VCC$2… etc. or VCC@1, VCC@2. So the pin naming doesn’t seem to work as described.
Does it work in other predefined library parts? Perhaps you can open/edit one of the working parts in another library to verify how to do it…
ok! i did just that and it seems that you use the @ but the catch is you must leave one of the pins with the base name with no extension. IE. GND, GND@1, GND@2, etc. Seems to work fine! thanks!
That may have been changed in later versions of Eagle. I’m using 5.2 right now and I can name pins GND@1, GND@2, etc. without having a pin named GND and it works fine.
You can do that in 4.16r2 as well. I use GND@1, GND@2… etc without any pin named just GND and it works fine.
