For small quantities, microchip's MP-LAB ICD (for around US$100) makes
programming 16f877's a snap. I use it all the time without any problems.

Subject: [PIC]: Cant program a 16f628 or a 16f877 w/ YAP-II. Buy
Warp-13?


Basically I haven't been able to program anything buy a 16f84 with the
YAP-II programmer.  I love the 'f84 and all, but I need other features.

I have tried several times to program a 16f628 and the chip gets hot, and
doesn't program.  I have spent some time investigating, and I don't know
what the heck is going on.

I also bought a few 16f877 parts, but can't get them to work either. (they
don't get hot, though)

Of course, I think I am hooking them up correctly, as far as I can tell
from the programming spec datasheet.

Anyway, I'm at my wits end here.  Myke Predko (designer of YAP-II) has
been nice enough to buy some 16f628 parts to try to figure it out, but
with no luck yet.

So, I saw this Warp-13 programmer on eBay, and it supposedly programs the
16f877.  I'm wondering if anyone has had any luck with this programmer.


Any input is welcome.  I'm about to go crazy.

-Steve
