Title: Power Ports
Post by: slowaudio on April 16, 2014, 02:16:23 am
So, how exactly do you make custom power ports? The few examples I've seen are a little vague. I've loaded some of the stock ones and there appears to be some fiddling with the designation to make it work, but I can't find any documentation about it.

Your question i so vague, we have no clue what you are talking about.
Can you provide a better description, or come context, or some examples?

Sorry, it was a little late...

I want to make custom power ports. The default power library doesn't have a +15V and -15V rail, so I want to make those power ports respectively. I've made custom parts before in KiCAD but have never made a custom power port and I'm looking to make some.

When you create a new part, there is an option to create a power part. Do you just create one pin and that pin is net connected to all other pins of that type? When I load a default power port the reference field is #PWR and the value is +3.3V (for example). So if I create power port part with 1 pin (electrical type: power input), and then give the part reference field "#PWR" and whatever value I decide, will all those power ports be connected then?

Never thought about it, I just re purpose the ones that are included for my own use hah. Sometimes confusing remembering the names. Probably a bad idea if you like the magic smoke staying inside your parts. Hmm.
