re-program stamp on the fly
Archiver
Posts: 46,084
Hypothetical situation. SUPPOSE I had a memory source like a compact
flash card or even traditional RAM loaded with STAMP programs...AND I
had a Stamp running a program...(has anyone successfully done
this)...using a master controller (possibly another stamp) halt the
first Stamp, download a new program and re-start the first stamp? I
know this is theoretically possible, but as far as I know, the stamp
can only be loaded from a PC. (Please don't tell me I have to have a
laptop dedicated to this system.... That WOULD be easiest, but I'm
looking for a small solution.)
(I sit around and think of these things... I need to get a life, in
fact... nine of them...)
Thanks

up and free... <sigh>) I believe that's as close as I'm going to get.
Realisticly, $119 is not an unreasonible price. Only problem would be
the lag time of selecting which program to download. I suspect it
could take at least 30 seconds to download 8 2K programs to the stamp.
I want this for a robotics system so time is critical. ...hmmm
depending on the final software, it may make sence instead to use a
back up stamp and pass control over to avoid the lag time... or even
have an "active" stamp and a "backup" stamp to program and switch into
active service as needed. (ok this just got real complicated fast.)
Thanks Russell, You're a great resource!

Well how about more EEPROM if you know in advance what
is required? STAMP program memory capacity is fixed
but that leaves two choices:
1. have spare programs in I2C eeprom and download them
to core EEPROM pages on demand and then RUN page to
start them - keeping PAGE 0 as a 'menu'. Here the
EEPROM would be filled by a 'loader' residing in PAGE
0 - you could tokenise on PC into say PAGE 1, then
use the loader to take it off chip until required.
Repeat until full...
2. modify your stamp to disable on board EEPROM and
bring another into play via their chip enable lines.
This would be a lot easier with OEM stamp as then the
EEPROM is in plain DIP package. I'd see this being
done with a bit of external hardware (maybe a STAMP1
but could also be implemented with a few bit counter
chain and a pulse generator 555 or 74123?) that
recognised a reload request, held reset down, altered
EEPROM CS lines and then raised reset, thereby
starting program in the 'other' EEPROM. These coudl be
programmed in normal way by manually overriding the
select process and loading each EEPROM in turn.

Hey that second idea is absolutely inspired! Piece of cake! I'm
an old "chip select hacker" from WAY back! ( I attempted to mate
memory to an old Timex 1000...I don't want to talk about it). I must
admit, I have never seen an OEM board before so I didn't know you
could get at the EEPROM.
The first idea... I'm still scratching my head on that one. You're
talking about a place I've never been. I'm not real good when people
use multi syllable words. Do you know anyplace I can find an example
of that?
Thanks for your help!

The Stache module is available for Parallax for $99. It takes the
same length of time to program a Stamp when using the Stache as it
does when using a PC with the STAMPW.EXE program or object loader.
That is about as fast as it gets. With the Stache, though, you don't
have to carry around a PC or boot it up. Usually you would not have
to update all 8 banks.
You might be interested to know that one Stamp can program another:
http://www.emesystems.com/BS2clone.htm
With the new stamps, the '2p and '2pe, it is possible to load in a
program using the STORE and WRITE commands, but that is slower that
the real programming algorithm used by the IDE or the Stache, because
the eeprom locations are written one by one instead of page by page.
The idea of switching between different eeproms on an OEM Stamp
should work, but I've never seen published instructions for a hack
like that.

from this setup. If you're only going to used 2 or 3, I'd
use seperate stamps and just use a master to switch the
appropriate stamp into the circuit.

re-program a basic stamp on the fly.
I've entered a autonomous robotics contest to take place in Belgium
in April of '04. I wanted to include my daugther's high school and so
I've chosen to go STAMP as much as possible to make it simple enough
for the students to understand and learn (and to keep me from falling
completely on my face...). I've had some experience with STAMPS having
been involved in the F.I.R.S.T. Robotics competition for several years
before moving to London. I've also linked STAMPS in a master slave
configuration so I'm confident in being able to make them talk
together with minimal effort.
There are three "sections" to the competition that the robot will
have to negotiate and my main concern is the amout of code it will
take to do all three. I was concerned that I may have to abandon the
STAMP as the major controller because the amount of coding may exceed
the programming space an individual STAMP so I wanted to explore the
possibility of reprogramming the master stamp or as an alternative,
passing control to a CO-master stamp... or even a second CO-master stamp.
Anyway, that's it in a nutshell and I THINK I've gotten the
information I need to press forward with a good degree of confidence.
Anyway, now you know the reason for the weird question.
Best Wishes
Steve CAT
Unless you're looking for simultaneous co-processing, this sounds
like a natural application for a BS2SX/p/pe. In essence, these
models have seven additional, firmware-selectable EEPROM banks, much
like what you're contemplating.

Steve
