Hi Michael,
What I meant was to use the I/R beams (4) as you described, but to
simply connect their outputs in parallel with each other, each through a
diode, so that if any of them were to register a dog "hit", that beam sensor
would pull down your signal line through its diode, to stop your counter.
The diodes would provide some isolation between the I/R sensors, since
we don't know the sensor's output configuration, and to simply connect all
four of them together might cause problems, the diodes are a way to do
it more safely.

| Hi Michael,

| | Hi List:
| |
| | This is my first posting to the list. I am an occasional electronics
| | hobbyist (and Ham - AA4YH) from Cary, North Carolina. I bought a BS-1 a
| few
| | years ago and fooled around with it, making some LEDs blink, etc.
| |
| | I now have a real project that I'm trying to design. The target
| | microcontroller is still undetermined, but I'm leaning toward the OOPIC
| (I'm
| | a computer scientist by profession, and like the programming paradigm of
| the
| | OOPIC).
| |
| | Here's what I'd like the advice of the list on: I am designing a race
| timer
| | for timing flyball races. Flyball is a relay race for dogs - they have
to
| | jump four hurdles, and press the pedal of a spring-loaded box, which
| | releases a tennis ball, then return with the tennis ball, across the
four
| | hurdles; repeat with next dog.
| |
| | I want to time the start/stop with a beam break detector. Since the
dogs
| | that run these races can be any size, my plan is to use a total of four
| | beam-break detectors in the same vertical plane at four or six inch
| vertical
| | spacing. I'm thinking infrared LEDs and phototransistors. What I'd
ideally
| | like to do is to use only one I/O line to detect whether any of the four
| | beams have been broken. I don't need to know which one was broken, only
| that
| | one of them was broken.
| |
| | I suppose I could build something like a four-input OR circuit, but I'm
| | wondering if there isn't some way to create a serial chain of these
| | detectors, and just detect a high-to-low (or low-to-high) transition if
| any
| | beam is broken.
| |
| | Does this make sense? Any thoughts? Any thoughts on my choice of
| | microcontroller or LED/phototransistor combination?
| |
| | Thanks folks. This is a great list!

As many of you said, my diodes do have part numbers on them, and I did save
the
tag in the bottom of my parts bin. They are indeed the 1N914's.
Thanks to everyone for their inputs and teaching. Your responses have
provided me with numerous little learning tasks to cement these studies.
I also searched on the optoisolators and started learning about them. Of
course I immediately have questions. Hoping that I haven't already worn out
my
welcome, I will ask it.
Does the optoisolator have an internal LED and Phototransisoter inside the
chip?
The switching is done with only light? Since no electricity is passed
between
the circuits, they are isolated? If so, very cool.
Thanks again.

Yup. There is no electrical connection between the input and output on the
opto-isolator. These are typically used to isolate a low-voltage circuit
from a high-voltage circuit. We used them to drive 110 VAC relays with
logic-level signals.
You'll still probably have to use a transistor to drive the relay -- most
opto-isolators are very low current.

The switching is done only with light. Inside the optoisolator
(photocoupler) is a LED and either a photodiode or phototransistor.
Opto's come in a ton of flavors...
Some are used as triac drivers. What this means is that your stamp
could switch an AC load (like your coffee maker or lights) with just
a small handful of parts, and without using a relay. Sometimes the
relay is a good choice, but is is a mechanical device, it is slow,
noisy, and being a mechanical device has a much shorter life than a
solid state switch (like a triac)
Opto's do many, many other things.
if these things interest you I would recommend you get a trial copy
of Nuts and Volts magazine (www.nutsvolts.com) and consider
subscribing.
I am a new "stamper", I got my BS2 three weeks ago. I have found NV
to be very stamp-friendly. A good source for electronics info, and
for stamp hints. I am 44 years old and my electronics education
stopped about 20 years ago, until three weeks ago, when I got my BS2.

I recently purchased a BSI for a project I'm working on. I plugged
it into my comp and powered it up to pin 1 with a 9v battery. Every
time I tried to connect I got an error hardware not found error. I
called parallax and it seemd my comp/parallel port were messed up. I
made sure everything was right and it still didn't work. After
calling them again they told me to check the voltage on the pins.
Pins 2-5 show about 9v. The service guy told me the regulator was
broken or something like that and that I had caused the dmage. Since
the specs say pin 1 can handle 4.5-12v I don't think I did anything.
Has anyone heard about BSIs that have arived DOA(dead on arrival)?
Does anyone know how I can fix this problem(other than buying a new
chip)? Thanks for any help.

Have you considered triacs? I ended up using something like a solid state
relay in an 8-pin dip package. I would look at the voltage you want to
switch and look for a triac or other device which will do it.
FYI, I ended up using digikey's PVT422ND dual relay package to use a stamp
to switch a 320V Peak-Peak AC signal at about 6khz, which I used for an
electroluminescent wire prjoect.

Sorry for the off-list topic, I hope someone here might be able to help.
I am doing a comparison of the 3 Chip Plus and the Basic Stamp kit as two
systems used to teach control techniques at schools. I was looking for some
information on what the 3 Chips are, and what they do. I know there is the
6502 processor and the 6522 (?) VIA interface chip (not sure exactly what
this does), but do not know what the third chip is. If anyone can help,
could you please contact me off-list. My e-mail is timproject82@h...
Personally I like optos, I've used them alot in robot applications.
They really do protect a lot of sensitive electronics from high current
lines going to a motor. They also cut out any knid of noise that
motors will generate. Plus optical anything gives it a very high tech
ambience.

I'm hearing alot about opto-isolators. Can anyone recommend a few part
numbers that work well with stamps? I'm looking for smaller footprint
types, I've seen them in an 6 or 8 pin dip before. I'd be interested in
ones that could do 12vdc at around 1A, and ones that do 120vac at 1A.
Also simplicity of design is good too. If I don't need a farm of external
components, I'd love to start using them. Just never had any good leads on
ones that would match up well with stamps.

I work for a large ISP in my area, these "anti-spam" organizations are more
of an inconvenience to ISP's like us then to spammers. They just move on to
other ISPs. In the mean time, our paying customers have to deal with MONTHS
of rejected and returned E-mails. We do everything in our power to keep
people from abusing our services, boo hoo if they get a few pieces of spam
through, we'll catch it and SELF-ENFORCE. Sorry, but we were burned by the
"internet blackhole list" about a year ago, when we failed one of their
little "tests" that their server runs (no actual spam ever went through our
system, I've got all the logs to prove it).
Thank god for firewalls, every IP address in the class B that we trace back
to an anti-spam organization gets banned from SMTP and POP3 ports. Freaking
BS that we should have to go to these lengths just to provide un-interupted
service to our paying customers. Sorry for the very off topic post, but I
just get angry when hard working sysadmins lose money over what amounts to a
single click fix (delete). I doubt you get that upset when a piece of junk
snail mail comes into your box.. Do you call the post office and complain?
What do you do... throw it away....

Who the heck are these "Innovative Internation Institure" guys?!! I've

Microsoft, EPRI, The Big 3, etc. From my past experience I've seen many
people get tangled into stuff like these deals. I'd like to restate (as
somebody already had in this conversation thread), signing the contract
by itself is a tricky thing and over on top of that, these people are
asking for money.

One thing you seem to miss in your Post Office analogy is that the sender

Subject: Re: Might not be around too often anymore
I want to expand this subject area more. First, the BASIC Stamp carries a
heavy load out there in the world and it has to be reliable when it does a
pbasic command. Interrupts must be done under a control condition. To do an
interrupt in the middle of a command can in some cases mean trouble. You
could lock up your control sytem causing an operation not desired. Second,
the polling interrupts on the BS2p only become active after the pbasic
command has been completed. This way you, the programmer, know that the
command was completed when an interrupt occurs and the next command
resulting
from the interrupt was defined clearly in the program software. Third, the
pbasic commands allows the polling interrupts to be locked, if desired, and
the interrupt I/O pin causing the interrupt is stored in stamp memory for
programming input use. All pins can be interrupt I/Os which more than
available on a PC.
The BASIC Stamp is a simple reliable device and will always work well if its
design and firmware logic remains simple. I think time will prove this out.

Chuck

'Been distracted by a number of other things lately, so I went into lurk
mode and digest. Lurk mode off for a few minutes.
During the new century preparations, I was thinking about using a Stamp
to control speed of the generator. The thinking is that the Stamp would
monitor frequency and then adjust the speed to match the load through a
servo. While it's at such a casual job, it can also monitor oil pressure
and fuel level, sounding alarms as necessary, and maybe even firing the set
up when necessary, providing all the necessary controls for starting.
Everything else is easy to figure out, giving it brain time only, but
how to measure 60Hz close enough to keep it within one or two cycles normal
operation is the tough part. I may miss this reply, but I thought I'd throw
that out for grinding around in your brain. I figure one can add a few
bucks to a cheap generator and get one as good as far more expensive ones,
plus a few bells and whistles.
Actually the wall wart I had hooked up to the generator was to
a cheapo black and white 5" TV/FM radio combo, the kind that
run on 9 'C' batteries or a wall wart.
The TV reception was fine, didn't notice any degradation at
all and the TV was about 2' from the running generator, couldn't
hear anything though.
Like Carl mentioned there oughta be all kinds of neat possibilities
with a cheapo generator and a Basic Stamp.
This generator cuts in and out pretty much, it really seems like it
over corrects and then overshoots as you watch the cooling blower
driven govener pull on the throttle. Seems like a frequency counter
hooked up to a linear stepper might be a pretty neat solution.
Just wish I had the time.
Thanks,
Mark

Greetings All,
I was wondering if anyone had any ideas (links, code, etc...) for
running a BS2 as a _slave_ on the I2C bus? I've seen plenty of
examples for master applications, but none for slave. I've searched
this message board, no help - I've searched the internet, no help.
(Interesting side note, the word "slave" in your search terms turns
up more fetish sites than you can shake a stick at.)
Thanks in advance,
Thomas
According to the Basic STAMP manual (page 137, the page for the
command I2CIN) the BS2 cannot operate as a slave. The I2C definition
of a master is the device which generates the clock, and initiates
data transfer. The definition of a slave is the device which is
addressed by the master. The BS2 does not have a device type or a
unique address for the I2C bus, and thus cannot operate as a slave. I
have a small I2C tutorial at: http://www.high-techgarage.com/tutorial/i2c.php which goes over some
of the basics of I2C protocol. There is also a link on that page to a
copy of the I2C bus specification ver 2.1 which goes into lengthy
detail about device types and protocols.

It was a bad suggestion. A corrupt stack is going to be a sad face
anyway, so there is no point in clamping the overrun/underrun.
Right, it is up to the user to keep track of the stack nesting.
Great! It does take a lot of overhead in time and code, but it is
very systematic. What recursive function are you planning?
The code for the multi-byte push/pop could be shortened by use of a
FOR-NEXT loop:
PushLocal:
for X=0 to 9
put stackpointer-X,B16(X) ' implied array
next
stackPointer=StackPointer-10
return
PopLocal:
for X=1 to 10
get stackpointer+X,B16(10-X) ' implied array
next
stackPointer=stackPointer+10
return
>Variable definition have to be very precise (use predefined names like W0
>to declare variables at a known location).
That is another subject! I prefer _not_ to use the fixed names
(w0,..,w13; b0,..b25, nothing for nibs nor bits). Instead, I name
global _word_ variables in every bank. Being words, the compiler
puts them first in the memory map. I then name my global bytes, nibs
and bits as chunks within those words. For example,
sxword var word
sxgo var sxword.byte0
sxaux var sxword.byte1.nib0
sxflag0 var sxword.byte1.nib1.bit0
There is (hopefully) some main RAM left over in the memory map after
the global variables. I use that for local variables, named with
meaningful names as usual, and the compiler will position them
automatically above my global variables no worries. I just think it
comes out more readable and maintainable that way.
The stack mechanism would in any case provide a good way to store up
all of those global variables if the entire RAM was needed for some
completely different purpose. For example, I had one application
reading out the packets of data from an Oregon Scientific weather
station, and the only way to capture all of the data was to free up
the entire ram. So I had to "stack" my main variables in scratchpad
while the BS2sx program jumped to another bank to capture the packets
of data. I didn't use a real stack for that, just an ad-hoc buffer.
(Now, the BS2p offers the SERSTR modifier that allows data like that
to be captured directly to the scratchpad RAM).

You could READ the individual bytes from 0 to 2047 and calculated a
checksum or CRC. Since you mention program slots, maybe you also
want to do that on a BS2sx, BS2e or BS2p. It is easy to extend the
checksum to all banks on the BS2p, because you can access the entire
eeprom memory through use of the STORE command. On the BS2sx or
BS2e, you will have to load a small program into each bank to check
the eeprom memory for that bank.

Subject: Re: beam break detector
Hi Michael,
What I meant was to use the I/R beams (4) as you described, but to
simply connect their outputs in parallel with each other, each through a
diode, so that if any of them were to register a dog "hit", that beam sensor
would pull down your signal line through its diode, to stop your counter.
The diodes would provide some isolation between the I/R sensors, since
we don't know the sensor's output configuration, and to simply connect all
four of them together might cause problems, the diodes are a way to do
it more safely.

|
| | Hi List:
| |
| | This is my first posting to the list. I am an occasional electronics
| | hobbyist (and Ham - AA4YH) from Cary, North Carolina. I bought a BS-1 a
| few
| | years ago and fooled around with it, making some LEDs blink, etc.
| |
| | I now have a real project that I'm trying to design. The target
| | microcontroller is still undetermined, but I'm leaning toward the OOPIC
| (I'm
| | a computer scientist by profession, and like the programming paradigm of
| the
| | OOPIC).
| |
| | Here's what I'd like the advice of the list on: I am designing a race
| timer
| | for timing flyball races. Flyball is a relay race for dogs - they have
to
| | jump four hurdles, and press the pedal of a spring-loaded box, which
| | releases a tennis ball, then return with the tennis ball, across the
four
| | hurdles; repeat with next dog.
| |
| | I want to time the start/stop with a beam break detector. Since the
dogs
| | that run these races can be any size, my plan is to use a total of four
| | beam-break detectors in the same vertical plane at four or six inch
| vertical
| | spacing. I'm thinking infrared LEDs and phototransistors. What I'd
ideally
| | like to do is to use only one I/O line to detect whether any of the four
| | beams have been broken. I don't need to know which one was broken, only
| that
| | one of them was broken.
| |
| | I suppose I could build something like a four-input OR circuit, but I'm
| | wondering if there isn't some way to create a serial chain of these
| | detectors, and just detect a high-to-low (or low-to-high) transition if
| any
| | beam is broken.
| |
| | Does this make sense? Any thoughts? Any thoughts on my choice of
| | microcontroller or LED/phototransistor combination?
| |
| | Thanks folks. This is a great list!

course I immediately have questions. Hoping that I haven't already worn out
my
welcome, I will ask it.
Does the optoisolator have an internal LED and Phototransisoter inside the
chip?
The switching is done with only light? Since no electricity is passed
between
the circuits, they are isolated? If so, very cool.
Thanks again.

Yup. There is no electrical connection between the input and output on the
opto-isolator. These are typically used to isolate a low-voltage circuit
from a high-voltage circuit. We used them to drive 110 VAC relays with
logic-level signals.
You'll still probably have to use a transistor to drive the relay -- most
opto-isolators are very low current.

Subject: Re: 5VDC Reed Relay
Yep
The switching is done only with light. Inside the optoisolator
(photocoupler) is a LED and either a photodiode or phototransistor.
Opto's come in a ton of flavors...
Some are used as triac drivers. What this means is that your stamp
could switch an AC load (like your coffee maker or lights) with just
a small handful of parts, and without using a relay. Sometimes the
relay is a good choice, but is is a mechanical device, it is slow,
noisy, and being a mechanical device has a much shorter life than a
solid state switch (like a triac)
Opto's do many, many other things.
if these things interest you I would recommend you get a trial copy
of Nuts and Volts magazine (www.nutsvolts.com) and consider
subscribing.
I am a new "stamper", I got my BS2 three weeks ago. I have found NV
to be very stamp-friendly. A good source for electronics info, and
for stamp hints. I am 44 years old and my electronics education
stopped about 20 years ago, until three weeks ago, when I got my BS2.
It is never to late to learn. Good Luck

Subject: BSI Problems
I recently purchased a BSI for a project I'm working on. I plugged
it into my comp and powered it up to pin 1 with a 9v battery. Every
time I tried to connect I got an error hardware not found error. I
called parallax and it seemd my comp/parallel port were messed up. I
made sure everything was right and it still didn't work. After
calling them again they told me to check the voltage on the pins.
Pins 2-5 show about 9v. The service guy told me the regulator was
broken or something like that and that I had caused the dmage. Since
the specs say pin 1 can handle 4.5-12v I don't think I did anything.
Has anyone heard about BSIs that have arived DOA(dead on arrival)?
Does anyone know how I can fix this problem(other than buying a new
chip)? Thanks for any help.

Have you considered triacs? I ended up using something like a solid state
relay in an 8-pin dip package. I would look at the voltage you want to
switch and look for a triac or other device which will do it.
FYI, I ended up using digikey's PVT422ND dual relay package to use a stamp
to switch a 320V Peak-Peak AC signal at about 6khz, which I used for an
electroluminescent wire prjoect.

ones that could do 12vdc at around 1A, and ones that do 120vac at 1A.
Also simplicity of design is good too. If I don't need a farm of external

I work for a large ISP in my area, these "anti-spam" organizations are more
of an inconvenience to ISP's like us then to spammers. They just move on to
other ISPs. In the mean time, our paying customers have to deal with MONTHS
of rejected and returned E-mails. We do everything in our power to keep
people from abusing our services, boo hoo if they get a few pieces of spam
through, we'll catch it and SELF-ENFORCE. Sorry, but we were burned by the
"internet blackhole list" about a year ago, when we failed one of their
little "tests" that their server runs (no actual spam ever went through our
system, I've got all the logs to prove it).
Thank god for firewalls, every IP address in the class B that we trace back
to an anti-spam organization gets banned from SMTP and POP3 ports. Freaking
BS that we should have to go to these lengths just to provide un-interupted
service to our paying customers. Sorry for the very off topic post, but I
just get angry when hard working sysadmins lose money over what amounts to a
single click fix (delete). I doubt you get that upset when a piece of junk

Who the heck are these "Innovative Internation Institure" guys?!! I've
been in the software consulting for over 14 yrs. I used to consult for
Microsoft, EPRI, The Big 3, etc. From my past experience I've seen many
people get tangled into stuff like these deals. I'd like to restate (as
somebody already had in this conversation thread), signing the contract
by itself is a tricky thing and over on top of that, these people are
asking for money.
Second of all, if this deal is so lucrative, why can't you guys look in
the head-hunters? Not in e-grps or newsgrps - it by itself sounds very
un-professional.
A big No-No!!!

So explain this:
To use MSN Messenger Service to chat with a co-worker, I had to sign up for
a Hotmail account. This email address is not shown in my MSN Messenger
profile and I have never given out this email address or sent any email
from it. I get 2-3 pieces of Smile mail a month, not even addressed to me.
Sounds like the provider isn't doing a very good job. I complain, and
receive no answer. Never had a problem with any small providers -- only big
ones. Now you know why the anti-spam groups exist.
One thing you seem to miss in your Post Office analogy is that the sender
pays the postage. With email, the receiver is paying the postage in the form
of a monthly fee and possibly per-minute connection fees.

Subject: Re: Might not be around too often anymore
I want to expand this subject area more. First, the BASIC Stamp carries a
heavy load out there in the world and it has to be reliable when it does a
pbasic command. Interrupts must be done under a control condition. To do an
interrupt in the middle of a command can in some cases mean trouble. You
could lock up your control sytem causing an operation not desired. Second,
the polling interrupts on the BS2p only become active after the pbasic
command has been completed. This way you, the programmer, know that the
command was completed when an interrupt occurs and the next command
resulting
from the interrupt was defined clearly in the program software. Third, the
pbasic commands allows the polling interrupts to be locked, if desired, and
the interrupt I/O pin causing the interrupt is stored in stamp memory for
programming input use. All pins can be interrupt I/Os which more than
available on a PC.
The BASIC Stamp is a simple reliable device and will always work well if its
design and firmware logic remains simple. I think time will prove this out.
Regards,
Chuck

'Been distracted by a number of other things lately, so I went into lurk
mode and digest. Lurk mode off for a few minutes.
During the new century preparations, I was thinking about using a Stamp
to control speed of the generator. The thinking is that the Stamp would
monitor frequency and then adjust the speed to match the load through a
servo. While it's at such a casual job, it can also monitor oil pressure
and fuel level, sounding alarms as necessary, and maybe even firing the set
up when necessary, providing all the necessary controls for starting.
Everything else is easy to figure out, giving it brain time only, but
how to measure 60Hz close enough to keep it within one or two cycles normal
operation is the tough part. I may miss this reply, but I thought I'd throw
that out for grinding around in your brain. I figure one can add a few
bucks to a cheap generator and get one as good as far more expensive ones,
plus a few bells and whistles.

Subject: Re: Cheapo generators & Basic Stamps
Thanks Rodent, Scott, Jay, Ray, Mike, Ice!
Actually the wall wart I had hooked up to the generator was to
a cheapo black and white 5" TV/FM radio combo, the kind that
run on 9 'C' batteries or a wall wart.
The TV reception was fine, didn't notice any degradation at
all and the TV was about 2' from the running generator, couldn't
hear anything though.
Like Carl mentioned there oughta be all kinds of neat possibilities
with a cheapo generator and a Basic Stamp.
This generator cuts in and out pretty much, it really seems like it
over corrects and then overshoots as you watch the cooling blower
driven govener pull on the throttle. Seems like a frequency counter
hooked up to a linear stepper might be a pretty neat solution.
Just wish I had the time.
Thanks,
Mark

Greetings All,
I was wondering if anyone had any ideas (links, code, etc...) for
running a BS2 as a _slave_ on the I2C bus? I've seen plenty of
examples for master applications, but none for slave. I've searched
this message board, no help - I've searched the internet, no help.
(Interesting side note, the word "slave" in your search terms turns
up more fetish sites than you can shake a stick at.)
Thanks in advance,

Subject: Re: I2C slave Stamp
Thomas,
According to the Basic STAMP manual (page 137, the page for the
command I2CIN) the BS2 cannot operate as a slave. The I2C definition
of a master is the device which generates the clock, and initiates
data transfer. The definition of a slave is the device which is
addressed by the master. The BS2 does not have a device type or a
unique address for the I2C bus, and thus cannot operate as a slave. I
have a small I2C tutorial at:
http://www.high-techgarage.com/tutorial/i2c.php which goes over some
of the basics of I2C protocol. There is also a link on that page to a
copy of the I2C bus specification ver 2.1 which goes into lengthy
detail about device types and protocols.
Good luck with your I2C project!

It was a bad suggestion. A corrupt stack is going to be a sad face
anyway, so there is no point in clamping the overrun/underrun.
Right, it is up to the user to keep track of the stack nesting.

Great! It does take a lot of overhead in time and code, but it is
very systematic. What recursive function are you planning?
The code for the multi-byte push/pop could be shortened by use of a
FOR-NEXT loop:
PushLocal:
for X=0 to 9
put stackpointer-X,B16(X) ' implied array
next
stackPointer=StackPointer-10
return
PopLocal:
for X=1 to 10
get stackpointer+X,B16(10-X) ' implied array
next
stackPointer=stackPointer+10
return

That is another subject! I prefer _not_ to use the fixed names
(w0,..,w13; b0,..b25, nothing for nibs nor bits). Instead, I name
global _word_ variables in every bank. Being words, the compiler
puts them first in the memory map. I then name my global bytes, nibs
and bits as chunks within those words. For example,
sxword var word
sxgo var sxword.byte0
sxaux var sxword.byte1.nib0
sxflag0 var sxword.byte1.nib1.bit0
The names are aliases. The global words and chunks thereof appear in
every bank.

There is (hopefully) some main RAM left over in the memory map after
the global variables. I use that for local variables, named with
meaningful names as usual, and the compiler will position them
automatically above my global variables no worries. I just think it
comes out more readable and maintainable that way.
The stack mechanism would in any case provide a good way to store up
all of those global variables if the entire RAM was needed for some
completely different purpose. For example, I had one application
reading out the packets of data from an Oregon Scientific weather
station, and the only way to capture all of the data was to free up
the entire ram. So I had to "stack" my main variables in scratchpad
while the BS2sx program jumped to another bank to capture the packets
of data. I didn't use a real stack for that, just an ad-hoc buffer.
(Now, the BS2p offers the SERSTR modifier that allows data like that
to be captured directly to the scratchpad RAM).

You could READ the individual bytes from 0 to 2047 and calculated a
checksum or CRC. Since you mention program slots, maybe you also
want to do that on a BS2sx, BS2e or BS2p. It is easy to extend the
checksum to all banks on the BS2p, because you can access the entire
eeprom memory through use of the STORE command. On the BS2sx or
BS2e, you will have to load a small program into each bank to check
the eeprom memory for that bank.
