Create PIC18F4550 package

#1 · September 8, 2026, 8:58 pm

I'm trying to create the footprint for the PIC18F4550, but as you can see in the photo, there's a "line" above the first pin that I haven't been able to remove. I'm attaching some files and a screenshot.

Hi.

PIC18F is not supported in SimulIDE, your component will not work.

The problem in package could be RA6 missing in package file, instead it has:

<pin type="nc"  xpos="-8"   ypos="112"  angle="180" length="8"  id="OSC2"  label="Osc2" />

Probably this should work:

<pin type=""    xpos="-8"   ypos="112"  angle="180" length="8"  id="PA6"  label="A6/Osc2" />

Thanks for your attention. I’ve created the PIC18F core and added the PIC18F4550, and I’m currently running tests. I’m not sure if you saw the .png file, but it’s already running in the recompiled program; I just added EEPROM and comparator support. If everything goes well with other projects, I plan to add other PIC18F models I have sitting in stock.

Ok, nice.

Confirmed: problem with extra pin is solved changing OSC2 Pin to:

<pin type=""    xpos="-8"   ypos="112"  angle="180" length="8"  id="PA6"  label="A6/Osc2" />
