Hi all,

I posted gifs of the Pocket programmer schematic and PCB overlay if
anyones interested. The source will be out soon.

Hi, yep we're interested! :o)
Did you menton if the pocket programmer does individual
serial numbering yet? This would make it perfect for us,
at the moment we have to edit asm source in mplab,
recompile, and program each chip with PicStart plus.
This is a hassle when doing big quantities.

Roman,

I'm not sure if you're using Linux or not, but if you were you could use Andrew
Pine's Linux PicStart Plus driver and write a script to help automate batch
programming. If you didn't feel like editing the hex file with a script, then it
would be trivial to place the serial number into an include file, include it in
the source and then re-assemble it with gpasm. The serial number can
automagically be incremented by the script.

Hi Scott. Thanks for the help. We don't use Linux,
but that was a clever idea using batch files and
gpasm. Does gpasm drive the PicStart plus direct or
would I still have to use MPLAB??

Tony's pocket programmer appeals to me as it could
be used in the workshop as part of the assembly
process, at the moment the programming is done in
the office on the PC, then back to workshop, it is
a hassle.

Having a cheap, simple standalone programmer that
could be used in the workshop by less skilled staff
as part of the total assembly process would be ideal.
:o)

The software I have for my programmer (EPIC+ from MELabs) will do serial
numbering on its own...

It's a parallel port PC programmer.  I think the programmer is pretty much
a run of the mill Tait style, it's the software that does the serial
numbering -- your choice of program memory location, EEPROM or ID bytes.
Not standalone, though.

Hi Roman,

That's the idea of providing the project as open source. Just add more
functionality yourself.

I was just thinking on how to implement this feature. I have not needed
serial numbers yet, so I assume they are stored in the ID registers.

The Pocket's FAT system has a 32 byte header space for each HEX file
stored in EEPROM. I can implement a 16 bit word in this info so that it
is incremented by 1 everytime that particular file is used for
programming. This value will be placed into the ID regs when programmed.

The Pocket can have an extra menu function added to enable/disable the
ID override and a way of editing this value. The serial number will be
reset to 0000h when uploading a file from the PC to the Pocket memory.

Is this what you had in mind?

Here is a gif of the Pocket's PC interface. There is nothing much there
except a way of editing the data file for the PIC chips. The Pocket
actually tells the PC to bring up file load dialogs and such from it's
own menus.

I got most of the 18Cxxx routines working last night, but a new 18Cxxx
that I bought seems to be a dud. My other programmer won't even read
from it. Hopefully the local distributor will change it today.

Hi Tony, generally the special ID locations cannot be
read by the PIC itself. I prefer to put the ID in
the ROM as part of a general data table showing DOM,
batch number, firmware version etc. This can then
be read by the PIC itself and displayed when operating.

The ideal way to store the number in ROM is as one
or more RETLW bytes, for obviosu reasons. :o)

Having it open source is a good idea! I could modify
the souce and do it that way, just thought that you
may have other customers that want to number their
products.:o)

Hi all,

I uploaded another pocket version.

It fixed a bug that was reported and it now has a Windows programmer
interface and a PocketPro.exe file to control it.

That makes it a bench top programmer as well.

Excellent, I can't wait for the PCB's to become available.  I know this was
never intended to be a universal programmer, but just a suggestion for
future "feature creep", how about the ability to program serial eeproms such
as 24C16 etc? Unfortunately the pinout dosen't match that of any PIC I know,
but there are lots of unused pins at the bottom of the ZIF socket, so maybe
they could be used?  Perhaps an analogue switch to route the SCL/SDA lines
from the onboard EEPROM to the ZIF?

Cheers

Mike

I have some PCB's available now, but I want to wait until I get the last
of the parts and build a kit from scratch to make sure everything is as
it should be.

Why not use the ISCP adaptor and use RB6 and RB7 for the SCL and SDA
lines.

These pins are also available as an IDC header on the PCB.

I will modify the PCB and make them available from the main socket.

Hi all,

The Pocket Programmer kit is now available.

It contains the PCB all normal and surface mount parts, preprogrammed
16F876-20P, 96K EEPROM, LCD, 40 pin universal ZIF socket and a
pre-crimped ICSP cable and plug.

I built one last night which took about 2 hours and it went first go.
After 5 minutes to calibrate the variable VccP and upload the chip data
file, it was ready for use.

I tried to get the order page updated, but there seems to be a server
problem and I cannot get through on FTP, so I will try again tonight.

Since the pocket programmer is an open source, no hidden "gotchas" design
that Tony is making available for all of us at
www.bubblesoftonline.com/pocket/pocket.html
I feel comfortable being involved in both spreading the word, providing
information and making the kit easy to get for people who don't want to
track down all the individual parts and make the PCB themselves.

To help with shipping speed and cost for interested list members, I will be
stocking the kits in the US for Tony. Advanced orders (at reduced prices)
are being taken on the piclist.com web site at:
www.piclist.com/techref/microchip/devprogs.htm
Also, the bidding is still open (till the end of the month) on the assembled
and tested prototype unit that Tony donated to the piclist.com server fund.
http://www.piclist.com/techref/auction.asp?a=itm&i=26

I'm waiting to see who will be the first to "tweak" the source and add some
additional capabilities. In fact, a banner on all the site pages for a
month, a write up, links and "attaboy" (or "attagirl") to the first
contributor of any extension or bug fix to the open source and...

...$100 plus all of the above on the
http://www.sxlist.com
site to the first person who adds the ability to program any Ubicom SX
controllers.

Would any rAVRs care to match that for the AVR or other processors or
devices?

I have just finished building this excellent programmer and am impressed
with the flexibility it offers. Well done Tony for all the hard work.

My post is hopefully to stop me reinventing the wheel. Has anyone added new
PIC devices to the Chip Information File. I will start to look into adding
to the list but don't want to duplicate work already done.

Companies selling programmers have every reason to be worried of this
product. With the support of us out here we can expand the range of this
programmer
