'[PIC]: In Circuit Programming with a 16f630'
2005\06\23@153605 by Joseph Pantoga

I have been running into problems when trying to program a PIC16f630
via an ICD2 and the Universal Programming Module.  I believe I have
the jumper settings correct (VDD-pin1 Gnd-pin14, and Vpp-pin4.  I am
using USB to program with the ICD2.  I know that the 16f630 is
different in the fact that it has 14 pins instead of the usually
18,28,40 configuration, but does this pose a problem when programming
with the ICD2, is there a different configuration I have to use?  Help
please!

I don't know anything about this "universal programming module", but I can
tell you that the 16F630 has the programming pins on different lines than
the "standard" locations for 18 pins parts like the 16F628.  The socket will
have to be wired differently than for 18 pin chips regardless of the
programmer in use.

I was looking at the 16f630 datasheet, but are there PGD and PGC pins
for the programming module to hook up to?

Yes.  All serially programmable PICs, which is all recent PICs, use the same
electrical interface comprised of GND, Vpp, Vdd, PGC, and PGD.  Individual
bits are transferred the same way, but unfortunately everything above that
varies a great deal accross all the PICs.

The Universal Programming Module is basically a 40-pin ZIF socket on a small board with an RJ11 socket (? ICD2
connector) and a patch-setup so that the pins of the ICD2 socket can be connected to any of the 40 ZIF
positions, as needed.  So the user "wires" the socket as needed for any particular chip - hence the
"Universal" description :-)  I note the OP didn't mention connecting PGD and PGC, so this may be his problem!

yes, I figured it out, not only was I not connecting PGD and PGC, but
I was not providing enough voltage, as you need to have the ICD2
connected to both the computer and the wall.  Thanks Olin for giving
me assistance.
