'picstart+, Mplab selective address programming?'

OK, Now that I've typed an incomprehensible subject line, let me try to
explain what I'm looking for:

Using CCS compiler with MPLAB and PICSTART+, I cannot see any way to select
the address range that gets programmed in a 16F877. For short programs, this
ends up wasting alot of time programming empty locations.

Is there a configuration file, or some magic incantation I'm missing? Any
suggestions?

I'm getting interested in the rom zapper discussion, but I haven't looked at
how it would integrate with CCS. I did something similar a while back on and
AMD 29200, rather than uploading hex files, I sent compiled binaries via
Xmodem protocol. Worked like a charm, and saved countless hours of development
time.

However, I'd like to shorten the programming time on the picstart, as
described above, if for no other reason than "It ought to work right."

Thanks,

Phillip

I'm working from memory, so the details may be wrong.

Start MPLAB as usual, enable the PicStart+.  Select the target
device.  Then go back to the heading labeled 'PicStart+' and select the
option marked 'Program/Verify'.

A window opens where you can set the start and end address to be
programmed, as well as the configuration fuses.

Hope this helps.

Hi Phillip

You can select a range using the "picstart plus" pull down menu and selecting
the program/verify option. This brings up a dialog box that allows you to
specify a start and end address. Clumsy but it is an option.

I do know what you mean about long program times with the 16F877, MPLAB
and the picstart plus.

When I get a chance I will finally release the NewGen driver and the
optional picstart plus firmware patch and the engage toolbar.

Here is a little blurb from my help file.
http://www.new-elect.com/engage\hlp_wx13xmplab_launcher.htm

NewGen provides much faster programming for flash parts especially when used
with the NEWFOUND ELECTRONICS slightly patched version of the PICSTART PLUS
firmware. With the NewGen, New PICSTART PLUS firmware you can program 2k
worth of PIC code into a 16F876 or 877 in 26 seconds. To do the same with
MPLAB and the PICSTART PLUS it will take approximately 2 min and 5 seconds.

There is also an inbuilt multimode bootloader originally for firmware updates
that perhaps I can open up for general use.

While I have all this pretty well perfected I haven't been satisfied with
how I can distribute it in a way that is fair to all. (This is also the
WARP-13 driver and it cannot be effectively commercial software to those who
buy a WARP-13 and free to those who don't. )

Haven't sorted this one out yet.

Thanks to Dwayne and Jim. I'm running much faster now. Does anyone know how to
get MPLAB to remember the address range settings, or am I getting greedy now?

Two versions, free to upgrade. Its a very proven marketing method. It will
get you in the door where you would normally be ignored and then, assuming
your produce works well, when people want the extra abilities of your
programmer, they will buy from you.
