Hey Michael,

Forgive me if I'm stating the obvious here...

I'm assuming the "node not found" error comes up during the PCB update
process.  I believe the "node" is referring to the layout footprint pad 28.
Basically, protel is trying to add pad 28 to the net RH, but the pad cannot
be found. The solution is to make sure that the footprint for U222 in fact
has a pad 28.

Subject: [PEDA] Node not found


I've finished the schematic, built up footprints, and previewed the circuit
board update and cleaned up several simple errors, such as missing foot-
prints or misspelled ones.

But now it's stuck on a node not found error and I can't seem to get it
fixed.  The error message says it's attempting to add node U222-28 to net 
RH, and the error is node not found.  I've played with it quite a bit.  At
first I was getting many of the pins as nodes not found.  I fooled with
reconnecting the pins, refreshing the view, saving everything in save all,
and even closing Protel and reopening it.  I finally deleted the offending
chip and placed another one.  Now there's still one pin that it refuses to
acknowledge.

I also played with swapping nets hooked up to the pin to see if the problem
followed the net.  It doesn't.  It stays right with the -28 pin.  I've
also tried deleting that pin in the schematic library and then adding it
again.

Any ideas would be appreciated.

Thank you, Michael
