'[PIC]: Why isn't Picstart supported?'

Hi,

I got an older Picstart plus a couple months ago. When I first connected it
to MPLAB it warned me that new firmware was available, but I chose to ignore
that until I had experimented a bit. Everything was working fine. Managed to
program a chip or two. Its been about a month since I touched that computer
and now when I went back the programmer is no longer "supported"...what
gives? Might I have inadvertently changed some setting. The help files all
seem to indicate that this message means the programmer is out of date. But
if that's the case then why did it work in the first place?
Help is appreciated.
Nick

I think you either upgraded MPLAB or are now building for a chip that
requires the new firmware.  Either way you should really upgrade the
firmware.  If I remember right, the Picstart+ uses a 17C44 (you better
check).  I bought two of the JW versions of this part a long time ago and
swap them whenever I need to upgrade the firmware.  This has happened 2 or
three times now.

You might be able to get away with one, but I worry that the original
firmware might be completely unsupported some day.

Yes it is a 17C44.

That someday is now. The firmware for a PICStart+ purchased 5 years ago
is not compatible with the latest MPLAB. Fortunately for me, I had an
installation of MPLAB that was several years old and was able to upgrade
my PICStart+ firmware.

Ok, so I had switched the chip in the 'edit project' box to from a 16f84 to
a 16f877a. The latter is not supported by the firmware version I have. Once
it was reset the programmer works again, but I do have to upgrade so I can
use the range of chips. At least now I can upgrade at home since the 17c44
is supported.
Thanks for the help,
nick
